2.0 Introduction

2.1 The purpose of this Manual is to provide Offshore Crane Operators and

associated personnel with fundamental safe working procedures applicable to

offshore crane operations.

2.2 These procedures can be applied in respect of crane operations, regardless

of type, classification or location offshore.

2.3 They should be used in conjunction with and complement, relevant sections

of the individual installation’s own Safe Operating Procedures, with any applicable

Standing Instructions or Orders allied to crane operations and with BS 7121-Safe

Use of Cranes. Where applicable, relevant sections of the UKOOA “Guidelines for

the Safe Packing and Handling of Cargo to and From Offshore Locations” shall

be complied with.

2.4 S.I.2307 - The Lifting Operations and Lifting Equipment Regulations 1998,

(LOLER) which covers all aspects of lifting operations shall be applied.

Additionally appropriate reference should be made to other statutory instruments upon which LOLER builds. They

are:-

(i) S.I.2306 - The Provision and Use of Work Equipment Regulations 1998 (PUWER)

(ii) S.I.2051 - The Management of Health and Safety at Work Regulations 1999 (MHSWR).

It is essential that reference be made to these regulations when planning any lifting operations or procuring lifting

equipment (Ref. 5.1 to 5.13).

2.5 Where applicable the requirements of the Control of Substances Hazardous to Health Regulations 1999 and

The Manual Handling Operations Regulations 1992 shall be implemented at the worksite in the form of suitable and

sufficient assessments. Generic or “model” assessments are acceptable where similar activities are being

undertaken in similar places of work. However, these shall be reviewed if there is:-

(a) reason to believe that the content of the Assessment is no longer valid

(b) a significant change in the work activity or conditions.

2.6 Other Documents such as Client and Company Safety Management System Manuals, Interface Documents and

Standing Instructions relating to crane operations encompassed within the Company HSEQ Management System

should also be considered.

3.0 Arrival Offshore

3.1 On arrival on the Offshore Installation for the first time it is necessary for the Crane Operator to attend an

Installation Safety Induction briefing.

3.2 Thereafter at the commencement of his first work shift the individual designated by the Offshore Installation

Manager as the ‘Person Responsible for Lifting Operations’ must ensure that the Crane Operator is fully conversant

2


3

with the controls and characteristics of the crane(s) he is assigned to operate. The Crane Operator must also be

apprised of all other procedures and instructions which are relevant to the safe accomplishment of his duties. These

should include the Crane Manufacturer’s Operating/Maintenance Manuals, relevant sections of the Installation’s Safe

Operating Procedures Manual and all Standing Instructions or Orders relevant to crane operations.

3.3 The responsibilities noted above will generally be discharged through Line Supervision or, in the case of crane

familiarisation, a competent person (e.g. Crane Operator or Crane Mechanic/ Operator).

4.0 Competent Person - Crane Operations

4.1 In appointing an individual to the position of Crane Operator on an Offshore Installation/Rig, the Employer, and

where applicable the Owner, or his representative, will have satisfied themselves that the incumbent has been

adequately trained and is competent to fulfil all the duties relevant to the role and consistent with the Job Description

and Job Accountabilities.

4.2 As a ‘Competent Person’ - Crane Operations, the incumbent will be expected and should be able to, undertake

all required crane operations in a safe and controlled manner.

Note:- These conditions/expectations do not apply to personnel who are engaged on a crane operator training

programme - their crane operational activity will be strictly aligned to their levels of formal training and experience

4.3 When a situation arises, or a condition exists, where in the incumbent’s qualified opinion, the safety of personnel,

plant or equipment may be jeopardised, he/she will be expected/required to suspend lifting operations until such time

as control measures have been introduced to minimise or eliminate the potential risks.

4.4 When lifting operations have been temporarily suspended due to inclement weather or in the case of supply

vessel backloading/ discharging the prevailing sea-state, they should not re-commence until the crane operator is

satisfied that conditions have improved to within the safe operating parameters recommended by the Crane

Manufacturer or imposed by the Owner or Employer.

5.0 Lifting Operations and Lifting Equipment Regulations1998

5.1 Introduction

On the 5th of December 1998 Statutory Instrument 1998/2307 became law. SI 1998/2307 is the Lifting Operations

and Lifting Equipment Regulations (LOLER).

The regulations were made under the Health and Safety at Work Act 1974 (HSW Act) as a means of implementing

the lifting provisions of the Amending Directive to the Use of Work Equipment Directive (AUWED, 95/63/EC).

Unlike previous legislation used to control the operation and use of lifting equipment LOLER is industry wide,

covering all workplaces subject to the HSW Act.

Although LOLER covers all aspects of lifting operations and equipment reference is made to two other Statutory

Instruments, upon which LOLER builds. They are SI 1998/2306 Provision and Use of Work Equipment 1998

(PUWER 98) and SI 1999/2051 Management of Health and Safety at Work Regulations 1999 (MHSWR). It is

essential that reference be made to these regulations when planning any lifting operations.

This section provides a brief overview of the regulations.

5.2 Regulation 1 - Citation and Commencement

Synopsis

Lays out the overall scope and timing of the regulations at its highest level.

Key Points

• Came into effect for all lifting equipment on 5th December 1998.

5.3 Regulation 2 - Interpretation

Synopsis

A series of definitions used throughout the regulations with the ACoP giving guidance on the equipment and

operations which are covered by LOLER, although it is stressed that the list is not exclusive and all work equipment

associated with lifting or lowering of a load is covered by the regulations.

Key Points

Definitions of particular note are:

• “lifting equipment” - work equipment for lifting or lowering loads and includes its attachments for anchoring,

fixing or supporting it.

• “accessory for lifting” - work equipment for attaching loads to machinery for lifting (pendant, sling, shackle, etc.)

• “load” - includes material or people lifted by the lifting equipment

• “examination scheme”- suitable scheme drawn up by a competent person for such thorough examination of

lifting equipment at such intervals as may be appropriate for the purpose described in regulation 9

• “thorough examination” - means a thorough examination by a competent person including such testing as is

appropriate for the purpose

Examples

As the range of LOLER is all encompassing the following list of equipment covered by the regulations is by no means

exhaustive:

• Pedestal cranes

• Mobile cranes

• Overhead gantry cranes

• Loose lifting gear - chain hoists, lever hoists, slings, shackles, pendants etc.

• Lifts for persons or goods

• Abseiling equipment


4


5

• Sling-sets attached to containers or pieces of equipment

• Runway beams and padeyes to which lifting equipment is anchored or fixed

5.4 Regulation 3 - Application

Synopsis

Details the where and who to which the regulations apply.The where is anywhere that the HSWA applies and the

who is an employer whose personnel use lifting equipment.

Key Points

• Applies to all work locations covered by the Health and Safety at Work Act, which includes offshore installations

within UK territorial waters and the UKCS.

Roles and Responsibilities

Although LOLER uses the term employer rather than duty-holder any duties specifically assigned to the employer

can be assumed to apply to the duty holder, if they have any control over lifting operations.

Where a company provides personnel to undertake work which will involve the use of lifting equipment then that

company is regarded as an employer and has a duty under LOLER to provide persons competent to undertake the

work. A duty also rests with the controller of the work to ensure that the competency of the persons provided can be

assured.

5.5 Regulation 4 - Strength and Stability

Synopsis

Calls upon the employer to ensure that the lifting equipment and its load is of adequate strength and stability for the

anticipated use.

Key Points

To ensure adequate strength and stability you must:

• Take account of the combination of forces which the equipment may be subjected to

• Assess the implication of the weight of any accessories

• Ensure that the equipment is not susceptible to in-service failure modes (fracture, wear or fatigue)

• Have an appropriate factor of safety against foreseeable failure modes

• Take account of any combination of destabilising forces

• Provide resistance to overturning

• Where there is a significant risk of overload, for example offloading a supply vessel onto a platform, then the

lifting equipment should be fitted with equipment, which provides an audible, and/or visual warning before an

overload situation is reached.

Although the load does not fall within LOLER it is incumbent upon the employer (person in control of the lifting

operations) to ensure that any lifting points on the load are of adequate strength.

Examples

Points provided on a load to assist with lifting are regarded as part of the load and do not fall under LOLER; for

example padeyes built into a container. However, screw-in eyebolts would be regarded as lifting accessories and

would be covered by LOLER.

Equipment typically used for warning of overload is a Rated Capacity Indicator (previously called Safe Load

Indicators, SLI’s).

5.6 Regulation 5 - Lifting Equipment for Lifting Persons

Synopsis

This regulation takes precedence over all other LOLER regulations when the lifting of persons is to be carried out.

Lifting of persons in equipment which is not specifically designed for that purpose should only be carried out under

exceptional circumstances following a risk assessment and appointment of suitable supervision, not as a matter of

routine.

In essence lifting equipment for lifting persons must be designed so that persons cannot be harmed while travelling

or working from the carrier, fall from the carrier and escape in an emergency. In addition there should be devices in

place to prevent the carrier falling.

Key Points

The lifting equipment should be such as to prevent the passenger from being crushed, trapped, struck or falling from

the carrier, normally by fully enclosing the carrier.

While carrying out activities from the carrier to prevent the passenger from being crushed, trapped, struck or falling

from the carrier. In particular the risk assessment should identify:

• Any external equipment or structures which the person in the carrier may strike

• The need for non-slip flooring

• Devices required to prevent any doors inadvertently opening

• The need for safety harnesses and lanyards

• Devices should be in place to prevent the carrier falling on failure of the primary means of support such as

multiple ropes with independent anchorage, multiple cylinders and check valves for hydraulically powered

systems

• If a person becomes trapped in a carrier they should not be exposed to any danger and can be freed. The

passenger should be able to summon assistance and be competent to use emergency lowering or self-rescue

equipment provided.

• Where practicable access should always be gained by less hazardous means, particularly for regular or routine

operations.


6


7

If a crane is to be used for lifting persons then the following must be in place:

• Free-fall capability lock-out

• Hoisting and lowering limiters

• Rated capacity indicator and limiter

• Schedule of daily inspections of the crane and carrier by a competent person

• Adequate instruction for all persons involved - passenger, operator, supervisor, etc.


As a controller of lifting equipment or operations you have a duty to ensure that equipment which is not designated

for lifting persons is not used in this manner.

Examples

Common examples of equipment NOT designed for lifting persons but which are used are cranes (pedestal and

mobile), forklift trucks and telescopic handlers.

It is worth emphasising that lifting equipment (pedestal cranes in particular) are not primarily designed for lifting

persons and should only be used in exceptional circumstances.

5.7 Regulation 6 - Positioning and Installation

Synopsis

A very straightforward regulation whereby equipment must be positioned and installed so as to minimise the risk of

the equipment or its load striking a person or of control over the load being lost.

Key Points

In particular lifting equipment should be installed in such a way that:

• The need to lift loads over people is minimised

• Crushing is prevented at extreme operating positions

• Loads moving along a fixed path are suitably protected to minimise the risk of the load or equipment striking a

person

• Trapping points are prevented or access limited on travelling or slewing equipment

The employer must also minimise the risk of a load:

• Drifting - runway beams should be level and tag lines used to control the movement of long or awkwardly

shaped loads

• Falling freely - through the fitting of suitable devices such as multiple ropes, safety gear or check valves

• Being unintentionally released during a loss of power to the lifting equipment or through the collision of

equipment or their loads. The use of hooks with safety catches, motion limiting devices and safe systems of

work are possible means of minimising these risks.

5.8 Regulation 7 - Marking of Lifting Equipment

Synopsis

A basic requirement to mark the Safe Working Load of the lifting equipment on the equipment, or to make readily

available to the operator such information

Key Points

• Safe Working Load (SWL) - the maximum load that the equipment may safely lift.

• If it is not possible to mark the equipment with the SWL then a coding system or labels may be used.

• If the SWL is dependent upon the configuration of the equipment then the SWL for each configuration should

either be marked on the equipment or the information kept with the equipment where it is readily available to

the operator, for example load-radius charts.

• Where the SWL changes with the operating radius of the equipment then a load-limiting device may need to be

fitted to inhibit the equipment and provide visual and/or audible warnings.

• Lifting equipment designed for lifting persons should be marked as such and the carrier should display the SWL

and maximum number of persons, which may be carried.

5.9 Regulation 8 - Organisation of Lifting Operations

Synopsis

The basis upon which all other regulations in LOLER are formed this regulation calls for all lifting operations to be

carried out in a safe manner, under adequate supervision and following a plan.

Key Points

• The competent person planning the operation should have adequate practical and theoretical knowledge and

experience of planning lifting operations.

• The plan will need to address the risks identified during a risk assessment and should identify all resources,

procedures and responsibilities necessary for safe operation.

• The degree of planning will vary considerably depending on the type of lifting equipment and complexity of the

lifting operation and degree of risk involved.

• There are two elements to the plan: the suitability of the lifting equipment as per Regulation 4 of PUWER and

the individual lifting operation to be performed.


Under Regulation 8 the employer or controller of lifting operations has a primary responsibility to ensure that suitable

persons are appointed for planning and supervising of such operations.

For any lifting operation it is necessary to:

(a) Carry out a risk assessment under the MHSWR


8


9

(b) Select suitable equipment for the range of tasks

(c) Plan the individual lifting operation

Examples

The term “Competent Person” is not prescriptively described in LOLER and is used to identify a number of different

roles under the regulations. In practical terms the competency of a person may be confirmed by formal, vocational

qualification or through first hand knowledge of planning or supervising the lifting operations.

Reference should be made to the following publications for more explicit guidance on the safe use of particular items

of lifting equipment:

• British Standard BS 7121 - Code of Practice for Safe Use of Cranes

• North Sea Lifting - The International Rigging and Lifting Handbook

5.10 Regulation 9 - Thorough Examination

Synopsis

Throughout the life of any piece of lifting equipment it must be accompanied by a valid certificate to show that it has

been manufactured properly and subsequently received thorough examinations to ensure continued integrity and

fitness for safe use.

This regulation presents the owner and user of lifting equipment with a number of options, some prescriptive, for

establishing examination schemes.

The term “inspection” has a special meaning under LOLER and in general “thorough examination” should always be

used.

Key Points

• Employer must identify all equipment, which requires thorough examination.

• The employer shall ensure that lifting equipment transferred in or out of his undertaking has a valid thorough

examination record.

In-Service

• All lifting equipment deteriorates in use and therefore a thorough examination must be carried out.

• A choice exists, either to have the lifting equipment thoroughly examined at intervals no longer than those

specified in the regulation or in accordance with intervals specified in an examination scheme

• Thorough examination intervals under the fixed scheme:

• every 6 months if the equipment is used for lifting persons

• every 6 months for lifting accessories (slings, shackles etc)

• every 12 months for all other lifting equipment (chain hoists, lever hoists etc)

• A thorough examination must be carried out following exceptional circumstances which may have jeopardised

the safety of the equipment; for example, following an overload or changeout of a major load path item

• In addition to thorough examinations, where user risks have been identified inspections should be carried out.

The inspection should include visual checks and function tests and be carried out by persons competent to do

so.

LIFTING OPERATION PLANPAGE 1 of


14

6.0 Daily Inspection

6.1 Crane Access Ladders, Walkways and Hatches

6.1.1 Each time that they access the crane and prior to commencement of lifting operations, the Crane Operator

must ensure that all access ladders, walkways, gates and hatches are:-

1) free from obstruction

2) cleaned of any residual oils and greases and that:-

3) all deck plates are secured and access hatches closed

4) Service hoses, e.g., diesel, air, and water are neatly stowed

5) Warning signs and barriers are posted accordingly.

6.2 Pre-start Checks

6.2.1 Carry out a visual check of the crane to determine its serviceability. This

should include the boom, hook blocks, sheaves, wire ropes and pendants

(including spooling on drums, rope terminations and any anchorage points), cab

and machinery house cladding.

6.2.2 Ensure that the pre-start check list supplied by the Manufacturer or Owner

is completed. These should include a physical check of all oil levels, coolant level

and fuel level.

6.2.3 Check that all guards over and around moving machinery are in place and

secure.

6.2.4 Check that cladding and panelwork in crane operations cab and Machinery House is watertight in order to

prevent water ingress which may affect the operational integrity of the crane.

6.3 Housekeeping

6.3.1 Check machinery house is in a clean and tidy condition. Clean up any oil spillages and remove any loose

materials, e.g. tools, rags.

6.3.2 Ensure that all personal belongings or clothing are stored in such a manner that they do not interfere with the

proper control of the crane during operations.

6.3.3 Check that the operator’s cabin windows are clean, windscreen wipers are in good condition and that the

screen wash system operates.

6.3.4 Ensure that crane structures, walkways etc, are free from all loose material, tools etc, which may have the

potential to result in falling objects. It is imperative that a high standard of housekeeping is maintained at all times.


15

6.4 Start-up (Prime Mover)

6.4.1 Prior to start-up, ensure that all controls are in neutral position and that the

main clutch (where fitted) is disengaged.

6.4.2 On start-up of prime mover, ensure that all air and oil pressure gauges are

within safe operating range before carrying out function check of the crane

controls.

6.4.3 Carry out function check of all crane controls at the commencement of each

shift. On friction clutch and brake type cranes it is imperative that the co-efficiency

of these components are ensured as there is potential for ingress of foreign

material which could cause slippage, e.g. water, grease etc.

6.5 Overhoist Limits/Cut-outs

6.5.1 At the commencement of each shift, carry out a function check of the boom

minimum radius cut-out and the hook block (main/auxiliary) overhoist cut-outs. These

checks should be extended to include maximum radius and maximum pay-out limits,

when they are fitted.

6.5.2 Always approach limits with caution. During normal operation reliance must

not be placed on limit switches or cut-out devices to stop crane motions, crane

operators must always be aware of the proximity of equipment to limiting cut-out

devices.

6.5.3 Limit switches should not normally be overridden. However, on certain 1st generation crane types such as

NCK EIGER and Linkbelt where it is normally permissible to carry out lifting operations within the 1st stage electrical

(Mipeg) and 2nd stage mechanical limiting devices, extreme caution must be exercised by the crane operator.

The relevant sections of the crane manufacturers operations manual, client and company Standing Instruction and

procedures must be referenced and complied with.

If there is any doubt that the operation cannot be carried out safely the incumbent must suspend operations until

such time as control measures have been introduced, and all necessary precautions have been taken to eliminate

potential risks.

On completion of the manoeuvre, the crane operator shall ensure that the switch is returned to its normal position

and that the device is again fully operational.

6.6 Rated Capacity Indicators

6.6.1 Prior to the commencement of lifting operations, ensure that the rated

capacity indicator is serviceable. Check that the appropriate platform or sea-state

condition is selected and that the correct number of wire rope reeving is displayed.

6.6.2 Where a mechanically operated rated capacity indicator is in use, ensure

that the correct platform/sea-state cam is fitted.

6.6.3 Activate the test function to ensure that all visual and audible alarms operate correctly.

MIPEG1000


16

6.6.4 Ensure that appropriate load/radius chart is in good condition and posted at a strategic point within the

operator’s cabin.

6.7 Emergency Load Release and Gross Overload Protection System

6.7.1 Always ensure that the manually applied Emergency Load Release is secure and cannot be inadvertently

activated during normal operations. This type of system, where fitted, must be function checked in controlled

circumstances, generally with an unladen hook and only by a competent person who is authorised to perform the

activity. Procedures issued for this purpose must be strictly adhered to.

6.7.2 Where the integrity of the crane is protected by an automatic Gross Overload Protection system the Crane

Operator must ensure, prior to the commencement of operations each shift, that system pressures are within the

appropriate operating range.

6.7.3 Function testing of any such system must only be undertaken by authorised, competent persons, adhering to

procedures issued by the Crane Manufacturer, Owner or Employer.

6.8 Emergency Engine Stops

6.8.1 Never use an emergency stop to shut down an engine during normal operations. These systems should only

be used during a periodic function check or, if the normal stop system fails to operate, in the event of a dangerous

engine condition or component failure occurring.

6.9 Safety Equipment

6.9.1 The Crane Operator must carry out a regular visual e.g. (daily) check to ensure that all available safety

equipment such as life jacket, breathing apparatus and emergency escape equipment is secure and in good

condition.

6.9.2 The Crane Operator will ensure that the fire extinguishes provided are of the correct type and size as specified

by the Owner and that they are familiar with application and use of the units provided.

6.10 Refuelling the Crane

6.10.1 While refuelling of the crane is taking place, Crane Operators must observe the following minimum safety

requirements:-

6.10.2 Refuelling must not take place whilst the engine is running.

6.10.3 Refuelling operations are only to be carried out under the supervision of the Crane

Operator or Maintainer who must remain at the station during the refuelling operation. The

appropriate COSHH / Risk / Environmental Assessments must be taken into account prior to

commencement of the refuelling operation.

6.10.4 Extreme care must be taken to prevent overflow or spillage of fuel onto the engine,

exhaust or electrical equipment.

6.10.5 Ensure that all isolation valves are closed on completion of the refuelling operation.


17

6.11 Checks to be Carried Out During Operation of the Crane

6.11.1 Periodically check all gauges to ensure that all pressures and temperatures remain within the safe operating

range.

6.11.2 Listen for unusual engine and/or machinery noises.

6.11.3 Be aware of slight ‘shocks’ which could indicate bad spooling of hoist ropes or imminent

equipment/machinery failure.

6.11.4 If anything out of the ordinary occurs – Stop! Check! Report defects or malfunctions to the Line Supervisor,

Crane Mechanic or Owner’s Representative.

7.0 General Crane Operations

7.1 Signals

7.1.1 Lack of effective communication is one of the main contributors to safety problems arising from routine and

non-routine activities within industry.

It is therefore imperative that Crane Operators and Banksmen are familiar with the system of signaling used on board

the Installation. Banksman signals to British Standard BS7121 normally apply (see section 10.0).

7.1.2 The Crane Operator must ensure that the banksman signalling system is clearly displayed at a strategic point

within the crane operating cabin.

7.1.3 The Crane Operator is to make himself aware of all those personnel designated as Authorised Banksmen.

7.1.4 Only respond to hand or radio signals when they are given by an Authorised Banksman. The Crane Operator

should only respond to signals from other persons in an emergency situation, i.e. when the ‘stop’ signal is given,

either visually or orally.

7.1.5 When hand signals are being used, maintain visual contact with the Banksman. Lifting operations must cease

if visual contact is lost. These operations can only recommence when a clear line of vision is re-established.

7.1.6 When radio communication signalling is being used, the Crane Operator is to reach a clear understanding with

the Banksman before lifting operations begin. If there is any interruption to the communication (e.g. third party

transmission) the Crane Operator must stop the lifting operation immediately, until communication with the

Banksman is re-established.

7.1.7 When the Crane Operator’s ability to see hand signals from the Banksman is impaired by inclement weather

conditions or darkness, etc., crane operations are to cease if the Crane Operator feels that the operation cannot be

executed safely.

7.2 Load Handling/Movement on the Installation

7.2.1 Prior to commencing lifting operations, the Crane Operator is to take stock of the prevailing weather conditions,

e.g. wind speed/direction and visibility. Lifting operations shall not commence if the weather or environmental

conditions are liable to jeopardise the safety of the activity.


18

7.2.2 While there is a shared responsibility for the safety of each lifting operation (e.g. crane operator, banksman

and slinger) the banksman remains the person in charge of the lifting activity.

7.2.3 Before a load is attached, the Crane Operator must be aware of the weight of the load to be lifted and will

satisfy himself that the lifting gear being used is certified (eg colour coded), of sufficient capacity and is correctly

attached and positioned, so as to prevent uneven lifting or slippage of the load. (Responsibility for slinging rests with

the riggers or deck crew).

7.2.4 Prior to hoisting, ensure that the Banksman has correctly positioned the hook over the centre of the lifting

point, so as to alleviate any ‘drift’ in the load as it is lifted clear of the deck.

7.2.5 When lifting from baskets or containers the lift shall not commence until personnel are clear of the immediate

area of the lift, i.e. out of the basket or container.

7.2.6 As the load is lifted off the deck, monitor the Rated Capacity Indicator for a possible overload situation

developing.

7.2.7 At the commencement of the first lift, the Crane Operator must check the operation of the hoist brake.

7.2.8 Ensure that tag lines or handling lines are attached to long or awkward lifts, e.g. casing/drill pipe bundles,

completion baskets, etc. to facilitate safe handling of the load, except when backloading to supply vessels.

7.2.9 When moving loads across the deck of the installation, the Crane Operator should be aware of any other

activities/ obstructions within the crane radius arc and shall, whenever possible, avoid the movement of loads over

the heads of other personnel. Sound the crane horn as a warning to personnel.

7.2.10 When carrying out ‘blind lifts’, monitor the Rated Capacity Indicator for any loss or increase in the weight of

the load. This could indicate that the load has snagged on the superstructure or the adjacent equipment. Cease the

lifting operation and advise the Banksman.

7.2.11 Always keep loads within the specified radius of the crane. Do not permit Load Handlers to push or pull loads,

either manually or mechanically, inside or outside the working parameters of the crane. The crane hoist rope must

always be retained in a vertical state.

7.2.12 When the load remains static for any reason, the Crane Operator must not leave his position at the controls.

Where the load is to remain static for prolonged periods, engage the hoist drum brake and the boom drum pawl

(where these devices are not automatically applied) which shall prevent the lowering of the suspended load.

7.2.13 During crane operations, carry out all movements in a controlled manner. Smooth operation of the crane

reduces the possibility of the inherent risks involved with undue shock loading or stress to the structure and/or

machinery.

7.2.14 If weather conditions are/become adverse, resist pressure to carry out lifts which you consider dangerous.

Consult with your Line Supervisor and Responsible Person for Lifting Operations. The operation should be

suspended until conditions improve and you are satisfied that the lifting operation can be carried out without

compromising safety in any way.

7.2.15 Where lifting activities necessitate the Crane boom to operate in close proximity to conflicting structures such

as drilling derricks, telecom towers, accommodation structures etc, a toolbox talk and lifting plan should be carried

out between all concerned parties, outlining all associated risks and subsequent control measures to be taken.


19

7.2.16 Where a Crane boom is operating in close proximity to conflicting structures the Crane Operator shall ensure

that a Banksman is positioned at a point where he has a clear overview of the load, Crane boom and potential

contact points.

7.2.17 If at any point the Crane Operator becomes concerned that the boom is too close to a conflicting structure,

or that he has been instructed by the Banksman to undertake a manoeuvre which may result in a collision, he must

cease operations immediately and advise the Banksman of his concerns. Crane operations must not re-commence

until such time that appropriate control measures have been put in place and all necessary precautions have been

taken.

7.3 Cargo Handling - Supply Vessels

7.3.1 Establish radio communication with the Captain of the supply vessel or where

applicable the vessel’s deck crew.

7.3.2 Prior to the commence-ment of discharging and backloading of cargo from/to

supply vessels, confirm the prevailing wind and sea-state conditions.

7.3.3 Ensure that the Rated Capacity Indicator is adjusted to register the appropriate sea-state condition. Any

alteration in sea-state during cargo handling operations should be taken into account and the Rated Capacity

Indicator altered accordingly.

7.3.4 Be aware of the weights of the cargo to be discharged/back loaded from the supply vessel. Obtain a copy of

the cargo manifest, prior to commencement of the operation.

7.3.5 Prior to hoisting loads off a supply vessel deck, ensure that the ship’s crew have reached a position of safety

well clear of the cargo handling area and have given the appropriate signal or instruction to hoist.

7.3.6 Prior to backloading cargo to a supply vessel deck, ensure that the ship’s deck crew are in a position of safety,

well clear of the intended cargo stowage area.

7.3.7 When hoisting loads off a moving supply vessel deck packed with cargo, the Crane Operator should be alert

for snag-ups or loads which are still lashed to the deck or for wrongly manifested cargo weights.

7.3.8 During lifting operations, particularly whilst engaged in supply vessel activities, the Crane Operator shall take

all necessary actions to avoid excessive impact and avert shock loading being transmitted to the crane. The Crane

Operator should wait for the correct moment to make the lift, and should not be rushed by frantic arm waving from

the vessel deck crew personnel.

7.3.9 Where practicable the Crane Operator should not use maximum boom radius during supply vessel

discharging and backloading operations. The Crane Operator shall assess each individual situation taking into

account the supply vessel “drift” movement and prevailing environmental conditions. Some boom radius should be

retained in reserve, to compensate for the “drift” movement in the event that it is necessary to abort the operation in

instances when the supply vessel is unable to hold station alongside the installation.

7.3.10 If a load is immersed in the sea for any reason, be aware of the possible increase in weight from water

absorption. Report the incident to the individual designated by the Offshore Installation Manager as the Responsible

Person for Lifting Operations so that he can check the load and/or contents for any damage sustained following its

retrieval.


20

7.3.11 Whenever possible, hoist/lower loads over open water and not over the supply vessel deck.

7.3.12 When discharging long tubulars, baskets or other awkward loads, ensure that hand lines are attached to

assist with the control and handling of the load on the installation deck.

7.4 Crane Operation - FPSO’s / DSV’s

7.4.1 The Crane Operator shall exercise extreme caution during Crane Operations on FPSO’s / DSV’s. Primary

considerations should include:-

• Vessel stability (pitch, roll, and heave)

• Proximity to “live” process plant or other equipment

• Establishment of realistic operational limitations

• All individuals involved in the lifting operation shall be familiar with the crane operational characteristics and

parameters. They should also be familiar with the working environment and the combined behavioural pattern

of the vessel and crane(s)

• Potential dangers while carrying out lifts outwith the Crane Operator’s line of vision i.e., “blind lifts”

• That handlines of appropriate length and strength should be attached to guide and steady loads.

• That a crane lift should not commence until such time as the intended landing area has been checked to ensure

that there is adequate room to receive the load. The Crane Operator, in conjunction with the person in charge

of the lifting activity shall also ensure that a Banksman and Load Handler(s) are in position to receive the load

prior to its initial movement. The only exception to this is when the Banksman and Load Handler(s) have

sufficient time during the transfer of the load to take up position on the intended landing area.

7.4.2 In addition to the primary considerations the Crane Operator should be aware of the following potential

problems inherent to lifting activities on FPSO’s / DSV’s:-

• Snagging or collision potential during operations close to conflicting structures/plant.

• Difficulty in controlling lateral movement of the load while carrying out lifting operations adjacent to process

plant or down hatches due to the various forces being applied to FPSO’s / DSV’s

• Loss of control being exacerbated as boom radius is increased

• Forces being applied to the Crane structure as a result of swinging loads.

7.4.3 Problems inherent to lifting activities during Supply Vesseldischarging/backloading operations

• Danger to Supply Vessel crew from “swinging loads” or hook(s) fitted to cargo handling pendant(s)

• Snagging potential ever present when discharging cargo

• Combined dynamic forces applied to crane are increased during Supply Vessel operations giving greater

potential for incident

• Excessive movement at stern of vessel where FPSO / DSV cargo is normally stowed relative to short crane

boom.


21

7.5 Bulk Hose Handling

7.5.1 The Crane Operator must exercise extreme caution when transferring bulk/liquid hoses between the

Installation and supply vessel. Follow the Banksman's signal and monitor the Rated Capacity Indicator for any

sudden increase in weight which may indicate that the hose has snagged on a protrusion on the Installation or supply

vessel.

7.5.2 In instances where a dry bulk hose has to be cleaned out by releasing a charge of high pressure air through

the system, the Crane Operator must establish radio contact with the bulk handler prior to commencement of the

operation.

7.5.3 The open end of the hose must be lowered to a position near sea level and at an angle from the Installation

whereby dry bulk dust will be carried down wind, thus preventing ingress to plant or accommodation air intakes.

Shipping in the vicinity should be warned.

7.5.4 Only when the Crane Operator gives the signal that the bulk hose is suitably positioned can the bulk handler,

release air through the system.

7.5.5 The Crane Operator must not take action to re-stow or transfer the hose to a supply vessel until he receives

direct confirmation from the bulk handler that the line has been depressurised.

7.6 Personnel Carrier Transfers

7.6.1 Personnel carrier transfers to or from Offshore Installations are considered a high risk operation and should

only be used in exceptional circumstances, ie emergency situation or when transfer is essential, and it is not

practicable to gain access by less hazardous means (see LOLER Regulation 5 and HSE Safety Notice 10/80)

Normally the Offshore Installation Manager is the only person to permit the use of Personnel transfer carriers.

The “Billy Pugh” type of personnel basket does not comply with Regulation No 5 of LOLER and should only be used

in exceptional circumstances.

The Duty holders policy on the use of Personnel transfer carriers, which should include authority and clearly define

the circumstances for use must be complied with.

7.6.2 Where it is necessary to transfer personnel to or from a vessel, the Crane Operator must always have a clear

view of the embarkation areas, load path and landing areas.

7.6.3 Check the prevailing weather conditions, e.g. wind speed and sea-state to ensure that they fall within the

criteria listed in the Installation’s own Safety Operating Procedures.

7.6.4 Where applicable, ensure that a secondary safety sling is attached between the carrier and the crane hook

block, and that a hand line of sufficient length is attached to assist with controlling the carrier while it is being lowered

to the supply vessel deck.

7.6.5 Establish radio communication with the Captain of the supply vessel prior to commencement of the transfer

operation.

7.6.6 Check that all other criteria required for the operation are met, e.g. stand-by vessel has been alerted,

passengers are wearing the appropriate immersion suits and life jackets and that they have been briefed on all facets

of the transfer. Particular reference should be made to embarkation and disembarkation methods.


22

7.6.7 Ensure that the personnel carrier is not swung over the side of the installation or the supply vessel until it has

been hoisted to a height where both the basket and the attached hand line are clear of all obstructions and potential

snagging points.

7.6.8 Ensure that the Banksman is on hand to take control of signalling in the event that visual contact with the

carrier or landing area is lost.

7.7 Helicopter Operations

7.7.1 All crane operations must stop during helicopter landings, unless

dispensation has been given to carry out special tasks.

7.7.2 If it is not a requirement to place the crane boom on the boom rest during

helicopter operations, liaise with the Helicopter Landing Officer to ensure that

the boom is positioned to prevent interference with the flying programme.

7.7.3 The Crane Operator must ensure that, before leaving the crane unattended, the crane boom is placed in the

boom rest and/or the slew brake applied. The crane must never be left parked with the boom in the proximity of the

helicopter landing deck.

7.7.4 Always ensure that aviation warning lights remain switched on when the boom is in the air and when 'A'

Frames or Masts extend to 15m or more above the heli-landing deck.

7.7.5 Where Installation instructions are available detailing the steps to be taken during helicopter operations, then

such instructions are to be implemented. The Crane Operator will ensure that he is familiar with the contents of the

Installation’s standing orders on this subject.

8.0General Instructions

8.1 Do Not’s

8.1.1 Do not operate the crane until you are certain that personnel descending from the

crane or its structure are well clear/outwith the swing path of the crane superstructure and

have signalled the all-clear to you.

8.1.2 Do not authorise access to the crane or its superstructure until the crane has been

brought to a complete halt. Ensure that personnel accessing the crane advise of their

intentions when on board. Signs which state that “Authorised Personnel Only Beyond This Point” shall be posted at a

strategic point, e.g., at the entrance of the Crane access point.

8.1.3 Do not lift loads outside or inside the working radius of the crane.

8.1.4 Do not depend on limits or cut-outs to stop the boom or load line motions.

8.1.5 Do not engage slew parking brake or lock until the crane superstructure has come to a halt.

8.1.6 Do not use slewing motion to drag loads over the decks.This imposes severe side stresses on the crane boom.

8.1.7 Do not carry out single point lifts with one handling pennant hooked into the other. This presents snagging

potential.


23

8.1.8 Do not, on cranes equipped with more than one hook block, operate the crane with a handling pennant or

other ancillary equipment attached to the stowed hook block.

8.1.9 Do not lift long or awkward loads without hand lines attached. (Except when backloading to supply vessels).

8.1.10 Do not lift personnel through the use of a Banksman – always insist on being able to see for yourself.

8.1.11 Do not continue with a lifting operation if you lose sight or radio contact with your designated Banksman.

8.1.12 Do not lift loads from baskets or containers until all personnel have come out of the unit concerned.

8.1.13 Do not interfere with Rated Capacity Indicators or other safety equipment attached to the crane. This is

illegal.

8.1.14 Do not allow personnel to ride on crane hook blocks or on loads.

8.1.15 Do not slew the crane outboard with a load on the hook when divers are working in the vicinity.

8.1.16 Do not leave the crane control cabin when there is a load suspended on the hook.

8.1.17 Do not use the crane if a fault or defect is liable to compromise the safety of personnel or lead to the possible

damage of equipment.

8.1.18 Do not tamper with or adjust any equipment on the crane unless you have the technical qualification, are

competent and/or are authorised to do so.

8.1.19 Do not operate the crane unless the Gross Overload Protection system pressures are in safe operating

range. (Where system fitted).

8.1.20 Do not over grease crane components. This could lead to brake and clutch slippages during lifting

operations.

8.1.21 Do not operate the crane in weather conditions outside the parameters laid down in the Installation’s Safe

Operating Procedures or Standing Orders Manual.

8.1.22 Do not lift loads of large surface areas, e.g. steel plates, in high wind conditions. Always assess the effect

the weather conditions could have on the behaviour of the load.

8.1.23 Do not carry out supply vessel discharging or backloading operations with the Rated Capacity Indicator

adjusted to platform duties. The appropriate sea-state duties must be selected and/or cam fitted.

8.1.24 Do not carry out cargo transfer to/from diving vessels or attendant semi-submersible unless the appropriate

sea-state duty has been selected.

8.1.25 Do not lift wire ropes, cables, or other material/equipment of a similar nature which are not already spooled

on drums provided for that purpose. An appropriate Risk Assessment must be conducted and one of the following

methods adopted:-

• The material has been coiled and then slung securely using an approved slinging arrangement method

involving at least a double wrap and bite


24

• The material can be lifted in a single strand provided the lifting arrangement is

(a) Secured approximately 1⁄4 to1⁄3 from one end by use of a clamp or other device to prevent the lifting strop

slipping.

(b) A certified lifting device specifically designed for the purpose is used.

8.2 Do’s

8.2.1 Do ensure that you are fully conversant with the relevant Installation Safe Operating

Procedures and Standing Instructions.

8.2.2 Do ensure that you are fully conversant with the controls and characteristics of the

crane you are about to operate.

8.2.3 Do carry out a visual check of the crane to determine serviceability.

8.2.4 Do complete the Manufacturer’s or Owner’s pre-start and operational check list prior to commencing crane

operations.

8.2.5 Do report any defects to your Line Supervisor or to the individual designated by the Offshore Installation

Manager as the Responsible Person.

8.2.6 Do post “Do Not Operate” signs in a prominent position in the operator’s cabin if the crane is out of use for

maintenance, etc.

8.2.7 Do ensure that the crane engine (or alternative power pack) is isolated and that systems have been

depressurised while maintenance is being carried out.

8.2.8 Do ensure that the Rated Capacity Indicator is fully operational and that the appropriate adjustments have

been made to suit prevailing conditions, e.g. platform/sea-state duties, number of reeving falls on hook block.

8.2.9 Do confirm the security of the manually activated Emergency Load Release controller to ensure that it cannot

be inadvertently activated.

8.2.10 Do be aware of the wind speed and direction and, where applicable, sea-state.

8.2.11 Do keep within the crane’s operating radius at all times during lifting operations.

8.2.12 Do make use of the crane’s boom safety pawl (if fitted) when lifting loads at long radii, heavy loads, when

raising boom from its rest, from across the deck, or when the crane is parked or under maintenance.

8.2.13 Do ensure that a cargo handling pendant, or sufficient length/capacity and sheathed in hi-visibility cover, is

used when discharging and/or backloading supply vessels.

8.2.14 Do ensure that only the required number of handling pennants for carrying out the lift are attached to the

crane hook, i.e. single point lift – single pennant (this particularly applies when engaged in supply vessel operation).

8.2.15 Do ensure that you are aware of any obstruction and/or activities that are ongoing within the operating radius

of the crane.


25

8.2.16 Do ensure that the Banksman has taken up position to determine the crane boom proximity to potential

collision points when carrying out lifts from areas such as the Drill Floor, Flare Tower Base, Radio Mast etc.

8.2.17 Do talk to the Banksman to ensure that you are aware of all aspects/requirements of the lifting operation to

be undertaken and of the signalling method to be used.

8.2.18 Do ensure that a Banksman is present when stowing the boom in its cradle.

8.2.19 Do function check all hoist and lower control systems prior to commencement of lifting operations. Particular

care must be taken when operating friction clutch and brake type cranes. Ensure the co-efficiency of these

components as it is crucial that they are maintained in a clean and dry condition.

8.2.20 Do operate the crane controls as smoothly as conditions allow and try to avoid ‘snatch’ as shock loading

imposes undue strain on the crane, its equipment and support structure.

8.2.21 Do exercise extreme caution when using friction clutch and brake type cranes to lower heavy loads. At all

times ensure that the load's speed of descent is retained under control and within the capabilities of the crane's load

lowering, transmission and braking system.

8.2.22 Do exercise caution when lowering the crane hook block such that the rope “payout rate” is not exceeded,

thus preventing possible damage to the rope.

8.2.23 Do everything possible to operate and maintain the crane in a manner which ensures the complete safety

of the crane, the Installation and all personnel in the vicinity.

8.2.24 Do talk to the Crane Operator from the previous shift before he leaves the crane to determine if the crane

has any defects which require immediate rectification or if there is any other important information which should be

known. Similarly, at the end of each tour of duty, ensure that “safety critical” information is relayed to relief personnel

on the proforma provided for the purpose.

8.2.25 Do ensure that loads are landed safely and the crane is secured if an Installation emergency occurs.

8.2.26 Do ensure that you are familiar with the operation of emergency load release and load lowering equipment

(if fitted).

8.2.27 Do ensure that during activities outwith the crane cab, your portable radio is secured to your person in a

protective pouch/holster by means of a waist belt or shoulder lanyard.

8.2.28 Do ensure that during crane maintenance activities that tools, equipment and lubricants are retained in a

secure manner. This is particularly important when working at heights. Where hand tools are being used in these

circumstances the use of a “tool saver” device is mandatory.

8.2.29 During winter weather conditions a build up of snow and ice on the crane boom is possible. When these

conditions prevail, crane operational personnel shall inspect the crane boom, and take necessary actions to ensure

the Hazard Potential is alleviated.


26

9.0 Banksmen / Slingers Procedures

Cranes can be dangerous machines in the wrong hands and, as such, require skilled persons to operate and

maintain them.

As well as the actual Crane Operator, at least two more important and essential members are required to make up

the team.

They are the BANKSMAN and the SLINGER. Accordingly the minimum number of personnel involved in each lifting

team shall be three. They are:-

i) the Crane Operator

ii) the Banksman

iii) the Slinger

While there is a shared responsibility for safety and efficiency attached to each lifting operation, the Banksman

remains the person in charge of the lifting activity.

These procedures should be implemented in conjunction with the crane operating procedures listed in sections 1-6

to form integrated Crane Operator and Banksman/Slinger procedures.

9.1.1 Risk assessments relative to Crane Operations are contained within the Sparrows assessment manual held

on each Installation where they have resident personnel assigned. These should be considered prior to

commencement of crane operations. Where appropriate, when an additional risk assessment is necessary, this

should be undertaken, documented and retained on record.

9.1.2 When the Slinger/Banksman and other crew members are involved in crane maintenance duties, such as rope

changes, the applicable Risk Assessments and COSHH Assessments shall be utilised for the activity. During such

activities either the Crane Maintainer, Crane Maintainer/Operator or Crane Operator will normally be designated as

the Task Supervisor.

9.1.3 The procedures contained within this manual should be used in conjunction with and complement relevant

sections of the individual installation’s own Procedures and Standing Instructions or Orders allied to load handling.

Other documents such as Client and Company Safety Management System and Quality Assurance System manuals

and Clients/Company Interface documents should also be given appropriate consideration.

9.1.4 It is anticipated that at the commencement of each shift all personnel involved in crane operations shall be

involved in a Toolbox Talk, and apprised of the lifting requirements and priorities for user departments. The allocation

of duties to achieve an efficient and safe operation shall normally be made by the Deck Foreman or deck crew team

leader.

9.2 The Banksman / Slinger

9.2.1 The Banksman controls the initial lifting of the load and its final positioning on the landing area or site. He

shall be assisted in each lift by the Slinger who also acts as the load handler.

9.2.2 Additional personnel shall be deployed as necessary as load handlers to ensure the safety of the lifting

operation.


27

9.2.3 The Banksman shall not get involved in the actual handling of the load. He/she must retain an overview of the

lifting operation at all times.

9.2.4 The Banksman and Slinger shall discuss each lifting programme with the Crane Operator to ensure that each

understands the sequence relative to the priority of lifts, any problems that are known or may occur, and the

methodology to achieve a safe and efficient lifting operation.

9.2.5 Prior to discharging or backloading of supply vessels the Banksman shall ensure that both he and the Crane

Operator are in possession of a copy of the cargo manifest and that a discussion has taken place with the Deck

Foreman with regard to the planning of the impending activity and the priority of lifting.

9.3 Safe Working Procedures

The Banksman must:-

9.3.1 Ensure that he is easily identifiable from other personnel by wearing a hi-vis jacket or waistcoat which is clearly

marked to indicate that he is an authorised crane Banksman.

9.3.2 Ensure that both he and the Crane Operator are aware of all aspects of the lifting operation to be undertaken.

9.3.3 Ensure that both he and the Crane Operator have agreed and are familiar with the method of signalling to be

used. All signalling must be conducted in a clear and concise manner (see Recommended Crane Signals - Section

10).

9.3.4 Be aware of the wind speed and direction.

9.3.5 Know the weight of the load.

9.3.6 Be familiar with the capacities and parameters of the crane in use.

9.3.7 Check that the lifting gear being used is in good condition, certified for use, correctly colour coded and of

sufficient capacity to carry out the lift.

9.3.8 Ensure that a cargo handling pennant of appropriate length and capacity is attached to the crane hook and

is suitable for the particular lift to be carried out. In the case of supply vessel operations the pennant deployed shall

under normal circumstances be no less than 10m and shall be sheathed with a hi-visibility cover.

9.3.9 Ensure that taglines/handlines are attached to any long or awkward loads to facilitate easier handling e.g.

casing, drill pipe, completion baskets, except when backloading to supply vessels.

9.3.10 Be aware of any obstructions within the crane’s radius and working area.

9.3.11 Check that the area around the load to be lifted is clear and that the load is not attached to the deck,

transportation cradle, or adjacent equipment. Ensure that taglines/handlines in use are not secured or tied off to

adjacent equipment or structures.

9.3.12 Be aware of potential snagging points in the vicinity of the load whilst hoisting/lowering in restricted areas.

Always check above to ensure that the crane’s hoist rope, hook block assembly and attachments have a clear

passage.

9.3.13 Ensure that he identifies escape routes for all parties involved with each lifting operation, should a problem

develop whilst, either lifting the load clear of the deck or setting it down in its final position.


28

9.3.14 If using hand signals, the Banksman shall stand in a position where the Crane Operator can clearly see him

and he can maintain visual contact with the load, load handler(s), and potential crane boom collision points such as

drilling derrick, flare tower, turbine exhausts etc.

9.3.15 When using radio communications to instruct the Crane Operator, the Banksman shall stand in a position

where he can maintain visual contact with the load, Load Handler(s) and potential crane boom collision points such

as the drilling derrick, flare tower, turbine exhausts etc.

9.3.16 Always use clear and distinct signals (either by hand or by radio) to control lifting operations. In poor light

conditions, exaggerate all hand signals.

9.3.17 When lifting, stop the load just clear of the deck to check balance and security of load. This will also give the

Crane Operator the opportunity to check the function of his hoist brake.

9.3.18 Make it clear to the Crane Operator where the load has to be moved to and placed. Ensure the receiving

landing area has sufficient room to take the load. If possible, precede each load to its destination. Alternatively,

ensure that another team are in position to receive the load.

9.3.19 Warn other personnel in the area of the movement of the load. Avoid moving the load over the heads of other

personnel.

9.3.20 Keep a check on other activities within the crane’s operating area to avoid the development of unforeseen

hazards.

9.3.21 When carrying out lifts, under radio communication, which are out of the line of vision of the Crane Operator,

normally deemed “blind” lifts, ensure that the Crane Operator receives a full briefing of the intended lifting

operation(s). Paint a verbal picture of the manoeuvres/load movement that are about to be carried out and do not

proceed until he/she gives an acknowledgement of understanding.

9.3.22 During “blind” lifts the criticality of the lifting operation may be such that there is a requirement for the Crane

Operator to acknowledge and repeat the instruction he has received over the radio. Ensure that no part of the lifting

operation proceeds unless a precise acknowledgement has been received from the Crane Operator.

9.3.23 During “blind” lifts which are being conducted by a hand signalling method and more than one Banksman is

being used to relay instructions to the Crane Operator, each Banksman should stand in a position where he/she can

be clearly seen by the next person in the chain. All signals should be clear and precise. The Banksman at the load

should have a complete overview of the activity.

9.3.24 When lifting operations are being conducted through hatches to lower decks, always barrier off the hatch

area and erect signs with a contact number. The barriers must not be removed until the hatch has been replaced and

is secure.

9.3.25 During overhead lifting operations e.g. on the drill derrick or flare tower assemblies, the area at deck level

shall be barriered off to ensure that personnel not involved in the operation do not encroach and expose themselves

to the danger of potential falling objects. Appropriate signs with contact numbers should be posted.

9.3.26 If the crane stops, be aware it may well be that the Crane Operator has lost sight of the Banksman’s signals,

or, if radio communication is being used, a third party has transmitted on the working channel. Re-establish visual or

oral contact.


29

9.3.27 While the crane is engaged in cargo handling operations with a supply vessel, the Banksman shall be

available to assume control of the operation if requested to do so by the Crane Operator in the event that he loses

sight of the supply vessel deck or an emergency situation arises.

9.3.28 When engaged in deployment or restowage of bulk hoses, the Banksman and Handlers must never stand

in a position where there is potential for entanglement in a hose or being struck by a falling hose. Other personnel

must be kept well clear of the area.The Banksman should stand in a position where a clear view of the hose handling

operation can be attained. (It is strongly advised that safety cages or framework are erected over hose handling

stations to protect personnel involved in such operations in the event that a hose becomes detached from the crane

or lifting arrangement).

9.3.29 Do not land loads on areas which are designated as “No Load” areas.

9.3.30 Do not direct the crane in a load path over “live” plant.

9.3.31 Do not use unorthodox slinging methods or uncertified lifting equipment.

9.3.32 Do not use the crane to drag slings or other lifting equipment from below loads.

9.3.33 Do not stack cargo carrying units, tanks or equipment, unless they are specifically designed for that purpose

and it is permitted by the Installation.

9.3.34 Do not allow the carrying of personnel in baskets or other equipment unless it is specifically designed and

certified for that purpose (Ref. LOLER Reg. 5).

9.3.35 The removal of barrels, drums etc. from transit carriers or containers shall be carried out using lifting

equipment specifically designed for that purpose. Always ensure the integrity of the barrel rim. This equipment shall

not be used when lifting barrels or drums across platform areas. Secure methods of slinging shall be used for this

task.

9.3.36 Prior to either transfer on the installation or to a supply vessel the security of cargo inside CCU’s or baskets

etc. shall be ensured. Additionally the doors of containers shall be secured by application of a ty-wrap or similar

method.

9.3.37 Prior to movement on the installation or to a supply vessel, all units or equipment shall be checked to ensure:

(i) the security of panels.

(ii) the security of hatches.

(iii) that no loose equipment, tools or debris are lying on roof, framework etc.

(iv) that all valves are closed to prevent spillage.

(v) that there are no protrusions liable to cause snagging.

9.3.38 Do not use plate clamps for the purpose of transferring steel plate around the Installation. The use of this

type of lifting appliance is restricted to situations where plate is being removed from a racking system or is being

moved short distances where the lift can be retained just above deck level. A safer more secure method of lifting this

type of material e.g. by applying shackles, or by adopting an appropriate slinging arrangement, should always be the

first priority.


30

9.3.39 Bundles of tubulars such as drill pipe, casing and scaffold tubes shall always be slung using the “double

wrap” slinging method. Appropriate rope grips/clamps and tie-wraps shall also be applied to ensure the security of

the slinging arrangement, which shall be applied 25% in from either end of the tubulars.

9.3.40 When guiding equipment into or out of baskets or containers always keep hands clear of the load to ensure

entrapment is avoided. Apply handlines for this purpose. Personnel shall not enter baskets or containers during these

operations.

9.3.41 Do not lift wire ropes, cables, or other material/equipment of a similar nature which are not already spooled

on drums provided for that purpose. An appropriate Risk Assessment must be conducted and one of the following

methods adopted:-

• The material has been coiled and then slung securely using an approved slinging arrangement method

involving at least a double wrap and bite

• The material can be lifted in a single strand provided the lifting arrangement is

(a) Secured approximately 1⁄4 to1⁄3 from one end by use of a clamp or other device to prevent the lifting strop

slipping.

(b) A certified lifting device specifically designed for the purpose is used.

9.3.42 On occasions when it is necessary to double stack equipment, ensure that the integrity of lifting tackle and

bridles is not jeopardised. Cargo or equipment stowed on top of containers etc. must be secured against movement

by wind or collision with other equipment. There may be a policy on the installation which does not allow double

stacking of equipment. If this is the case please adhere to it.

9.3.43 If anything out of the ordinary occurs, STOP the lifting operation and CHECK that it is safe to continue.

11.0 Controlling Crane Operations by Two Way RadioCommunication

11.1 Protocol for the Use of Two Way Radio Communication

11.1.1 Call signs should be set up and adhered to eg Alpha Deck, West Crane, etc.

11.1.2 Call signs must be used at all times in order to establish the authenticity of commands or directions.

11.1.3 At the end of an instruction or enquiry the transmitting operator should indicate the end of the message by

the command “over”.

11.1.4 The receiving operator should indicate understanding of the dialogue by the response “roger”.

11.1.5 Under no circumstances should the transmitting operator assume understanding without acknowledgement

ie “roger” from the receiving operator.

11.1.6 If any dubiety exists regarding a message the receiving operator must not acknowledge but should repeat

the message as he understands it and ask for confirmation or simply request the transmitting operator to repeat.

11.1.7 At the close of communications the transmitting operator should indicate the end of the transmission by the

command “over and out”.

11.1.8 Bearing in mind the broadcasting legislation, under no circumstances should profane language be used while

transmitting.

11.1.9 As these radios are transmitting at a high output, should the antenna ever become damaged exposing the

central core, the antenna must be immediately replaced in order to maintain not only optimum performance but to

ensure user safety.

11.2.1 The Crane Operator and Banksman should establish a clear understanding and line of communication prior

to the commencement of any lifting operation. Radio messages should reflect work requirements only. General

conversation should not be carried out over the air waves.

11.2.2 Always ensure that you fully depress the transmission button before speaking into the microphone. Speak

clearly at all times. Do not release the button until a few seconds after completing your message.

11.2.3 When banking the crane ensure that any accompanying colleagues’ radios are switched off. If more than one

radio is switched on in close proximity, it is inevitable that interference and/or distortion of the signal will take place

when an instruction is transmitted.

11.2.4 When a clear line of communication has been established with the Crane Operator ensure that if you move

position you re-establish that he is still receiving your message clearly.

11.2.5 During ‘blind’ lifts where the load is being hoisted or lowered for a long time (eg shaft/leg work) do not maintain

the transmission button in the depressed position for the duration of the lift. Likewise do not give an instruction at the

commencement of the lift and then cease communication until the lift has almost reached its destination. Give the

initial instruction and then talk to the Crane Operator every 10 - 15 ft to reassure him that the line of communication

is still active and that you are maintaining control of the lift.


32

11.2.6 During high winds ensure that the area of the microphone you speak into is not exposed to direct contact

with the wind. Otherwise the background noise created may distort the transmission.

11.2.7 Ensure the radio microphone is not exposed to rain. If a plastic carrying case offering full protection of the

radio is not available, a simple precautionary measure such as a small plastic bag or a piece of cling film around the

microphone will ensure it is maintained in a dry condition.

11.2.8 Do not carry radios in pockets. Always ensure they are carried in protective holsters attached to the body by

either shoulder lanyard or waist belt, quite apart from maintaining the integrity of the radio this measure will also

ensure that you are not exposing other personnel to danger should the radio be dislodged from your pocket or

dropped from the hand when working at height or climbing ladders.

12.0 Adverse Weather GuidelinesAdverse weather will increase the risks presented to personnel and assets as a result of lifting operations. To minimise the potential risk associated with liftingoperations the matrix below provides an example of operational limits for deck operations and factors that should be considered by those involved.

12.1 Electrical Storms

During electrical storms, lightning can have an adverse effect on the crane’s structure and to personnel involved in

crane maintenance activities and general crane hoisting and lifting operations.

Past experiences suggest that where the threat of lightning exists, crane maintenance activities and crane operations

must be suspended until such time as the risk of lightning affecting operations has abated.

13.0 Wire Ropes - Care and Inspection

13.1 Introduction

Wire ropes are used throughout industry on hoists, rope-operated plant and on all types of crane work.

Wire rope manufacturers have developed many types of wire rope construction. Each feature of construction has

some special advantage for a particular application. A wire rope of the wrong type will not give satisfactory service.

Always replace a worn out rope with the type recommended.

13.2 Factor of Safety

A safety factor is put on all ropes used in industry.

A sample piece of rope is tested to destruction and the breaking strain is then divided by the safety factor to give the

safe working load of that rope.

A test certificate is raised for each drum of rope at the manufacturers and a test certificate is issued with each length

from a drum, stating the safe working load of the rope.

13.3 Construction

Generally speaking, all ropes nowadays are preformed in manufacture and there are a great many different rope

constructions, each one having its own particular use.

There are three main things to observe when examining the construction:

(a) number of wires in each strand

(b) number of strands in the rope

(c) direction in which wires and strands lay (spiral) in the rope

Flattened strand. In extreme cases of abrasion, flattened strand may be used and this construction offers the

maximum wearing surface due to the strands being either triangular or oval, resulting in a wire rope with its

circumference forming an almost continuous circle. Flattened strand is supplied only in Lang’s lay.

Ropes are normally made in right-hand lay, but they can be supplied in left-hand if specially ordered.

There are three types of rope in common use:

Ordinary lay; Lang’s lay; Non-rotating


34

13.5 Ordinary Lay

In this construction, the wires and strands spiral in opposite directions:

in RIGHT-HAND ordinary lay, the wires spiral to the left and the strands to the right;

in LEFT-HAND ordinary lay, the wires spiral to the right and the strands to the left;

These ropes are easily handled, and can be used with one end left free to rotate, but they wear quickly because only

a few crown wires are in contact with the bearing surfaces at any one time.

13.6 6 and 8 Stranded Lang’s Lay

In this construction, wires and strands spiral in the same direction. Right-hand lay is usual, but it can be supplied in

left-hand lay:

6 and 8 Stranded lang’s lay rope has better wearing properties than ordinary lay, but it is harder to handle. Both ends

must be secured to prevent twisting.

13.7 Non-rotating

Both multi-stranded lang’s lay and ordinary lay are used, with a double-layer construction. If the inner rope is left-

handed lang’s lay, then the outer covering will be right-handed ordinary lay, or vice versa.

Non-rotating ropes resist twisting, and are ideal for long, unguided lifting purposes, particularly for crane hoist ropes.

Where high lifts are involved, a hoist rope having minimum rotational properties is required to eliminate “cabling”, and

here “Dyform” multi-strand non-rotating ropes are recommended.

13.8 Dyform Strand

Dyform strand - a product developed by British ropes - involves the spinning of conventional tensile wires into a

strand, which is subsequently drawn through a die. A high steel content in the strand results in much higher strength

than from a comparable size of conventional strand.

Breaking Load - Size Relationship

Dyform multi-strand wire ropes achieve minimum breaking loads approximately 23% above conventional multi-strand

construction in the same initial tensile.

Dyform multi-strand wire ropes have higher strength than the same size of standard size strand with a steel core.

These features eliminate the normal breaking load disadvantage associated with multi-strand ropes.

Right-hand Ordinary Lay(regular lay)

Left-hand Ordinary Lay(regular lay)

Right-hand Lang’s Lay


35

Crush Resistance

The high steel content available in Dyform multi-strand provides maximum resistance to crushing on multi-layer

drums. At the same time, the design gives excellent flexibility so that coiling on drums and pulleys having drum/rope

diameter ratios down to 14:1 creates no problems. The smooth periphery eliminates interference between adjacent

laps of rope on the drum.

13.9 Non-rotating Properties

The turn/load and torque/load graphs comparing Dyform multi-strand with conventional multi-strand construction

shows the very satisfactory characteristics obtained from the new product.

13.10Wirer Ropes - Care and Inspection (Summary)

Strength and Flexibility

• Strength depends on rope size, rope construction, wire tensile.

• The standard tensile for general engineering wire rope is 180 KG/mm2 (1770 N/mm2).

• Fibre Core may give impression of flexibility but can be a problem in difficult service conditions.

• I.W.R.C. support the load bearing outer strands of the rope.

• The greater number of wires in the outer strands, the greater the flexibility.

• The fewer numbers of wires in the strand, the better resistance to abrasion.

• LANGS lay in six and eight strand constructions, can only be used if both ends of the rope are fixed, or the load

is guided (i.e. not free to rotate).

• Corrosion will effect small wires more quickly than larger wires.

• Multi-strand ropes are prone to internal deterioration, are poor in bending fatigue but may be essential for some

applications where limited rotation is needed.

• Ropes are supplied preformed unless otherwise specified. In a preformed rope, the strands and wires have

been given the helix they take up in the completed rope. In a non-preformed rope the wires and strands are

held forcibly in position, and immediately fly apart when the rope is cut.

• Preforming balances the load on individual strands and equalises load distribution, the rope having less

tendency to form “high” strands even under the severest conditions.

13.11Rope Removal Criteria

• Consider which Regulations apply to your work and apply the relevant criteria where applicable.

• Recognise the Removal Criteria - 9 points. Consider the environment.

BRITISH STANDARDS – WIRE ROPE DISCARD CRITERIA

• Number, nature, type and position of visible broken wires in 10 x diameter maximum 5% of total number of wires

in the rope.

• Local Groups of Visible Broken Wires - A maximum of 3 in one or adjacent strand.

• Deterioration in the vicinity of the termination or terminal damage - no broken wires within 6mm of the

termination.

• Core deterioration - abrupt loss in diameter.

• Wear - Maximum reduction in diameter - 10% from nominal (6 & 8 Strand) 3% from nominal (multi-strand).

• Internal corrosion - Reject ropes if internal corrosion is confirmed.

• External corrosion - Corrosion causes very high losses in rope breaking load. Reject ropes of corrosion causes

wire slackness.

• Deformations

• Thermal damage.

13.12Factors Causing Rope Deterioration

• Deterioration may result from normal usage, from mis-use or as a result of abnormal incidents.

• NORMAL WEAR OCCURRING ON STRAND CROWNS The appliance (rope tension, number of sheaves,

condition of drum and sheaves, rate of acceleration/deceleration, inertia or momentum of sheave, fleet

angle).

The environmental conditions (abrasive dust, lack of or inability to adequately lubricate rope in service).

Degree of wear can normally be seen without difficulty

- measurement of rope diameter.

- assessment of the wear on individual visible wires.

Plastic flow on the wire surface.

37

• INTERNAL DETERIORATION

as interstrand, interwire, and strand/core interfaces. Notches/indents caused by pressure/friction - such

increase as rope tensions increase, sheave rope diameter ratio reduces, at high levels of bending cycles and

if there is a lack of adequate lubrication.

• CORROSION

Can be a major cause of rope deterioration.

Hostile environment - steam water, corrosive fumes, etc.

Contamination of lubricant - foreign matter, products of fretting.

Hot/cold environments - adequate dressing cannot be maintained.

External corrosion can normally be seen and assessed.

Internal corrosion more difficult.

• ABRASION

Usually at strand crowns and additional to normal wear.

Seized, misaligned sheaves.

Abrasion against structure, spillage, etc.

(the top of a trench as with an excavator drag rope)

• MECHANICAL DAMAGE

Incorrect reeving, displacement of rope from sheaves, poor coiling on drum (cross laps, sunken laps), incorrect

fleet angle, run over by tractors, struck by objects, incorrectly profiled sheaves and drum grooves, kinking and

bends caused during installation.

• OVERHEATING

Conduction, radiation, direct flame, electrical arcing. Can cause serious reduction in rope strength.

• MALFORMATIONS

Resulting from poor installation procedures.

Shock loading.

The introduction of turn (+ve/-ve) into the rope by operation of the appliance.

• ROTATION

Wrong rope for the duty.

Long lengths of rope with inappropriate handling technique.

• FATIGUE

Individual wires in ropes usually fail due to either being bent, tensioned or torsioned through large number of

cycles, or a combination of the three. Concentration of this condition - short rope movement.

• TERMINATION FAILURES

Incorrect fitting, corrosion fatigue, misalignment.

14.0 Use of Lifting Accessories

14.1 Introduction

The way lifting gear is used, and the conditions under which it is used, can often indicate special areas of attention

for the examiner.

This is especially true for gear used offshore, and in particular, for that used in the transfer of loads between ship

and rig/platform.

Anyone using lifting gear, must understand the effects of angles in lifting suspended loads. The principles of

TENSION are very important.

Simply, it can be said that: if a suspended load is hanging vertically, with no other movement, then the tension in the

supporting gear is equal to the weight of the load.

If the angle of the suspension is not 0 (or vertical), then the tension in the suspension must increase.

There are now two forces acting on the load. One vertical (gravity) and one horizontal.

Of course, when more than one sling is used on load, there is usually an angle between the legs, and this means

that the TENSION in each sling is MORE than the weight of its proportion of the load. (This would be half, for an

equally slung uniform load).

14.2 Principles of Tension

The tension in equally loaded slings is easily demonstrated using the following formula:

W x L= TENSION (in each sling)

No x H

W = Weight of load

L = Length of slings

No = Number of slings

H = Height (Vertical distance between attachment points)

It can be seen that tension will increase as the angle between the sling legs increases. (Fig. 1 & 2)

14.5 Sling Angles

When lifting with multi-leg slings, they are rated at a certain tonnage from 0o to 90o and this SWL should Not be

exceeded even if the angle is less than 90o. When using single slings in pairs however, you must always be aware

of the increased loadings in the slings when lifting at an angle.

For the above reason, the SWL of a pair of single slings decreases as the angle between them increases.

eg At 0˚ - SWL = SWL of one sling x 2

30˚ - SWL = SWL of one sling x 2 x 0.966




OR

At 0˚ - SWL = SWL of one sling x 2

14.6 Mode Factor (M)

Always consider the variation in sling capacity when slinging in various configurations.

Multiply the SWL of one leg by the mode factor - M to obtain the SWL of the configuration. (The last four

modes/ratings do not apply to “round” slings - Refer to table 3 at back of handbook).

If slings are used with a “choke” or “reeving” hitch, then there is another angle to consider, the angle at the “bight”.

14.7 Corrosion

Corrosion is a problem with lifting gear in general, and with offshore equipment in particular.

Exposure to sea water is an obvious reason, but there are also chemicals used during drilling, and production

operations, which can seriously affect the materials used in lifting gear manufacture.

15.0 Effects of Dynamic Loading

15.1 Introduction

It is a fact that a large proportion of lifting gear used offshore, is subjected to shock loading.

The effect of shock loading is to increase the weight of the load on the crane and therefore, on any lifting gear used.

The load is said to be increased “dynamically”.


Straight pullM = 1.0

Choke hitchM = 0.8

Basket hitchMax 90°M = 1.4

Basket hitchparallelM = 2.0

Two-legged slingMax 90°M = 1.4

Basket hitchParallelM = 4.0

Basket hitchMax 90°M = 2.8

Choke hitchM = 1.6

Straight pullM = 2.0

90°Max

42


Simply, if a load is lifted very slowly, gradually accelerated, then slowed down and stopped, it will remain “static”.

In other words, the effect of load on the equipment used for lifting, does not become more than the weight of the

load.

However, if load comes onto the equipment suddenly, or if a load being lowered is stopped suddenly, then the effect

of the load on the equipment will be to INCREASE the weight of the load.

It’s easy to see how this can happen when a crane is used to load or unload vessels at sea.

The movement of the vessel, and the hoist motion of the crane, can combine to produce severe shock loads which

can effectively, dynamically increase the load by as much as three times.

15.2 Dynamic Loading Graph

Everything between the load and the rig, or platform, is subjected to the “shock” and this includes the lifting gear.

Shock loading may well produce loads which exceed the proof load of the lifting gear, and in the case of chains,

shackles etc., this may result “permanent set”.

In the case of wire rope slings, twist will be induced into the sling.

Container slings are usually made up in assemblies, with relatively short sling lengths. As the twist in the slings is

“trapped” between the lower ring and the shackles the whole assembly becomes tangled and often the shackles

become “jammed” in their attachment points.

When this happens, the shackles will not pull into line with the sling and become loaded in the wrong direction. Also,

the length of the slings can become uneven, causing unequal load distribution.

16.0 Eyebolts

16.1 Introduction

Types of Eyebolts

Eyebolts are used for lifting loads which may be heavy and concentrated and are used for general lifting and for

permanent attachment to loads that need to be moved occasionally.

16.2 Safe Use of Eyebolts

The three types of eyebolts in common use are shown in figure 1. The use of the wrong type of eyebolt is not an

uncommon contributory cause of accidents. A typical example of this is where a dynamo eyebolt is used for other

than a vertical lift.

Dynamo eyebolts (a) are large enough to receive a hook of a comparable Safe Working Load (SWL) but should only

be used for a vertical lift because the eye is so large it is likely to bend should an inclined load be placed upon it and

in addition, a load which is only slightly out of the vertical places an undue stress upon the screw-threads of the

eyebolt shank. They should, therefore, be fitted in circumstances where it is possible to achieve vertical lifting at all

times, and, where dynamo eyebolts are fitted in pairs, it is essential that a spreader-bar should form an integral part

of the lifting gear and used to move the load. As was stated, the dynamo eyebolt is designed to receive the hook

direct, but when this is the case the hook should be able to work freely. It is dangerous to use a hook which jams in

an eyebolt because, under load, serious weakening of both eyebolt and hook could occur leading to failure at some

later date because of the incipient damage started at the time of the jam. If the hook available is too large for the

eyebolt concerned, a shackle of adequate size should be fitted to the eyebolt to accommodate the hook.

Where inclined to load conditions are encountered for example, when a multi-legged sling is used, collar eyebolts (b)

or eyebolts with links (c) must be used. The collar eyebolt which used to be referred to as the service eyebolt, has a

squat eye that is too small to accommodate a hook so a shackle is always necessary.

Fig 1

Collar eyebolts are intended for permanent attachment to heavy pieces of equipment and are usually fitted in pairs

for use with shackles and two-legged slings. When two pairs of eyebolts are fitted to a single load then two, two-

legged slings and a spreader-bar should be used in lifting.

The third type of eyebolt, the eyebolt with link, is intended for general lifting. Although its rated load decreases as the

angle of the load to the axis of the screw thread increases, by virtue of its special construction these rated loadings

are greater than those of a collar eyebolt of equivalent vertical S.W.L.

44


The collar, which plays an important part in the strength of the screw shank, should be machined smooth and flat,

and care should be taken to ensure that the mating surface is smooth, flat and at right angles to the axis of the tapped

hole. Figure 2 shows a close up of the collar of an eyebolt tight against the load to which it is attached and also shows

the chamfer on the edge of the tapped hole. The inset enlarges the area at the point where the thread ends and

where the shank joins the collar. The undercut and recess here are necessary to prevent stress build-up and the

dimensions of both are governed by BS 4278 : 1968.

The hole should be of sufficient depth to accept the full length of the eyebolt shank and to allow the eyebolt to be

pulled down tight. Comparison of the two eyebolts in Figure 3 clearly emphasises the importance of this point. The

plane of the eye should be in line with the direction of the pull, but where this is not possible a washer or horse-shoe

shaped shim may be used to alter the position to the required direction and still allow the eyebolt to be fully tightened

against the mating surface. The use of shims or washers should be avoided if possible, but if they are used they

should be of the least possible thickness and no more than one should be used. The thickness should never exceed

half the pitch of the thread on the shank of the eyebolt and the diameter should not exceed that of the collar under

which it is placed. The open part of a horseshoe shim should in all cases point away from the direction of an inclined

pull so that when the pull is taken the collar will always bed against solid metal.

16.3 Procedure for Using Eyebolts

• NEVER use HOME MADE eyebolts.

• Check the thread in a standard tapped hole. Fit is most important.

• Check the safe working load of the eyebolt before use.

• The shoulder or collar of the eyebolt should be flat, free from damage and at right angles to the threaded

portion.

• Examine the eyebolts for cracks, dents and corrosion pits before use.

• Check the eye for wear. If 1/10th or more of the original diameter is worn, replace it.

• Always ensure that eyebolts are screwed down tightly.

• Eyebolts without collars are substantially weaker that those with collars and are unsuitable for inclined loading.

• Remember that inclined loading substantially reduces the eyebolt’s safe working load.

• When using eyebolts, do not thread a sling through the eye of the eyebolt. Use a pair of shackles.

17.0 Estimation of Weight

17.1 Introduction

The most important step a Slinger must take with any lifting operation is first to find out the weight of the load. If this

essential information cannot be obtained, the Slinger must be able to calculate the weight using his own judgement,

and the use of the tables or data contained in this manual.

17.2 Weight Calculation

Then proceed as follows:

1. Calculate the weight of the object taking into account:

(a) The dimension of the object.

(b) The material the object is made of (steel, wood, concrete etc)

(c) Are there any lifting points attached to the object ie LIFTING LUGS, EYEBOLTS or any special sling attachment

points.

(Most lifting points welded to a piece of equipment will be made to accept a shackle. The lifting point will have a

machined hole to accept a shackle pin, with a nominal clearance, the size or S.W.L. marked on the shackle would

be of help to the Slinger).

• To the estimated weight add 25%. This will account for any errors of judgement.

• Now select the lifting gear for the overall estimated weight that is your estimated weight + 25% and sling the

load correctly.

The time taken to calculate the approximate weight of any object is time well spent, and may avoid a serious accident

through failure of lifting gear.

17.3 Weights of Various Materials

METRIC CONVERSION

To convert kilograms to (long) tons - multiply by 0.00098

To convert tons to kilograms - multiply by 1016.05

To convert feet to metres - multiply by 0.3048

To convert kilograms to tons - multiply by 0.001

To convert metres to feet - multiply by 3.281

ESTIMATION OF WEIGHT - ESTIMATE : THEN ADD 25%

2,240 lbs = 1 Ton (Long)

2,000 lbs = 1 Ton (Short)

20 cwts. = 1 Ton (Long)

1,000 kg. = 1 Tonne (Metric)
