Super Arch rubber fenders are manufactured using a twin leg system and can be mounted on a quay wall

horizontally or vertically to provide long lasting and low maintenance protection. The front face has a high

friction to limit vessel movement that is ideal for smaller vessels where friction is not a problem.

Super arch rubber fender has the higher performance than the traditional V & M type rubber fenders. Based on

the same unit weight of rubber, the energy absorption of super arch rubber fenders is 2.3 times higher than D

type rubber fender, 3.5 times higher than the cylindrical rubber fenders.

Super arch rubber fenders also can be bolted with UHMW-PE face pads, combining resilience with low-friction,

non-marking properties, called SA. This design can reduce the torsion the bottom of the fender dramatically,

then prolong the life-span of rubber fender body. The UHMW-PE face pads have various colors, and can be

replaced easily. SA and SAP Arch Rubber Fenders are available in many sizes from 200mm to 1000mm high

and in lengths of 1000mm to 3500mm. There are many types of rubber compounds as standard. Special

requirements also are available.

Features:

Easy to install and maintain

Tough and reliable design

High energy absorption and low reaction force

Wide ranges of sizes and energy capacities

Bolted-on UHMW-PE reduce the friction factor and shear force

Ladder Rubber Fenders are very robust but remain flexible to reduce accidental damage and help protect the

wharf when small craft berth.

Modular ladders are flexible, corrosion resistant and can withstand most accidental impacts from smaller

vessels. The step modules are made from polyurethane and can be linked together, combined with extensions

and a variety of optional handrails to suit many applications.

Berthing Velocity

Berthing velocity is an important parameter in fender system design, which depends upon the sizes of vessel,

loading condition, port structure and the easy or difficulty of the approach etc. Therefore the berthing velocity is

preferred to be obtained from actual measurements or relevant existing statistic information. When the actual

measured speed velocity is not available, the BSI and PIANC etc. standard shall be adopted to determine the

required velocity value from the following chart.

a Easy berthing and sheltered

b Difficult berthing and sheltered

c Easy berthing, exposed

d Good berthing, exposed

e Difficult berthing, exposed

The berthing velocity can be calculated more precisely by using the following formulation while the ship DPT

Cm Added Mass Coefficient (Cm)

When the ships berth at the dock, the body of water carried along with the ship as it moves sideways through

the water. As the ship is stopped by the fender, the momentum of the entrained water continues to push against

the ship and this effectively increase its overall mass. The mass of specified water is called Added Seawater

Mass, the added seawater influence coefficient is called Cm, normally calculated as the following formula

D-Draft

L-Ship length

ρ (ρ=1.025t/m3) Seawater density Cm=1+

Ce Eccentricity Coefficient (Ce)

In most cases there is certain angle (shown in the figure) exist when ships approach to the dock, therefore the

impacting point is not opposite the center of mass of the vessel, the ship will rotate so as to dissipated partial

ship impacting energy .The energy dissipated can be adjusted by Ce at berthing, the calculation formula is

stated below:

Ce= 1+(1/r2)

1

Where，

r = Gyration radius of ship against axial of center of

gravity on horizontal plane.

I = Project of the distance between the center of gravity and

berthing point on dock direction

Mid-ships berthing

Ce = 0.5

Ce = 0.6~0.8

Ce = 1

Abnormal Berthing Energy

Abnormal impacts may occurs for various reasons - engine failure of ship, breakage of mooring or towing lines,

sudden changes in weather or human error, the berthing energy will suddenly increased, it is suggested that

there should be a safety factor FS. then berthing Energy EA in abnormal berthing should be EA=FS.E, Fs2.

After the effective berthing energy of ship is determined according to item 2, the selection of fender system

shall be conducted in accordance with fenders performance (reaction force, energy absorption and deflection

curve) which shall

satisfy the following basic requirements:

a Energy absorption of selected fender system exceed effective impacting energy of ships.

b Reaction force of selected fender system is less than berthing structure allowable reaction force.

c Surface pressure of selected fender system is less than hull allowable surface pressure (to satisfy

requirements by changing the sizes of front panel)

d When the ship berthing in slanting direction, the fenders will bear angular compression which resulted in

decreased energy absorption, therefore the fender performance shall be adjusted in according with the

berthing angles while selecting fender system.

e The selected fender system shall be easy for installation and maintenance.

f The selected fender system shall satisfy the special requirements of adverse environment (such as high

temperature,strong wind and wave etc.) and of abnormal berthing.

g The selected fender system shall be high performance/economic, free of maintenance or low maintenance

ratio, that is the fender system shall be as cheap as possible in the investment, operation and maintenance

procedure.

Fender System Selection

Fender Arrangement

a. Vertical Orientation Arrangement

The fender system arranged in vertical orientation shall satisfy the purpose of all types and sizes of ship

berthing safely in all possible tide vary scope. The contact method of fender and ships are shown in the right

figures.

b. Horizontal Orientation Arrangement

The horizontal orientation spacing of fender depend upon the dock structure, berthing ship types and size and

berthing conditions etc, the most important is to ensure the ship will not contact the structure between two

fenders on normal berthing. The maximum fender spacing shall be calculated by the following formula:

S 2≤22r -( r-n )

Where,

S = Max. fender spacing

r = Bow radius

h = Fender height in rated compression deflection

Depth of Seawater Fender spacing along the dock

r

The bow radius shall be determined by the following formula:

r = 0.5 B 2 + L2 8B

B — Moulded breadth, L — Length overall

[( / ) ( / )]

The equal spacing arrangement is adopted by most of the docks , the fender spacing are shown in

the right table.

Front Panel Design

1.Design requirements

The main function of front panel is to distribute the reaction forces from fender units into the ship's hull, so the

design should be suit each individual berth. The loads and stress loads exert to front panel will depend on many

factors----the type of ship, berthing mode, characteristic of the rubber fender and tidal range etc. The design of

front panel should meet the following requirements:

1.1 Resistance to bending moments and shear forces

1.2 Resistance to impact on part

1.3 There is no deflection on front panel and face pad during the compression

1.4 Suitable corrosion protection for intended environment

2. The type of the structure of front panel

There are two types: open type and closed type. Regarding the open type ,it is consist of steel pad, H steel and

across steel .Closed type are consist of steel pad ,back steel and H steel

3. The determination of the dimension of the structure of the front panel:

The following requirement should be met in the design

P=∑R

A1B1≤ Py

Where

P= Hull Pressure (KN/m2)

P= The sum of maximum reaction force of all fender (KN)

A1= Valid width of front panel (m)

B1= Valid length of front panel (m)

Py= Hull allowable surface pressure (KN/m2)

Therefore if the allowable surface is known, the dimension

of the front panel can be determined.

4. The allowed hull pressure can be obtained from the following table if it's not available in design

Chain Design

1.There are three types of chains

In fender system: tension chain ,weight chain and shear

chain.

1.1 The main function of tension chain: protect the

fender from the damage while under local compression.

1.2 The main function of weight chain is to support

the weight of front panel and face panel.

1.3 The main function of shear chain is to protect

the fender from damage while in shear deflection.

2. The following items should be noted in chain design.

2.1 The chain dimension should be as exact as possible ,not too loose or too tight.

2.2 The chain can not be twisted as this reduces the load capacity.

2.3 Open link is preferred.

2.4 The initial (static) angle of the chain is important. Normally weight chains are set at a static angle

o o of 15-25 to vertical and shear chains are set 20-30 to the horizontal. Any failure will cause the chain

ineffective.

2.5 All the chains must be with safety factors which should be 2-3 times of the work load.

2.6 Shackle Selection

The dimension of the shackle is usually the same as the dimension of the chain. but if the shackle is

required to bear the same load with the chain, then thicker shackle is preferred.

Fender Performance Testing

The fender performance is determined by the absorbed energy and max. reaction force in the procedure

when the fender is compressed to the rated deflection.

In the performance testing procedure, the rubber fender is under direct force vertical to the fender

surface, the compression speed shall be 2-8cm/min repeating three times. Unless otherwise specified, the

deflection and reaction force shall be record to the nearest value to 1mm and 1.0KN (0.1ton)

The unit of energy absorption is KN-m(Ton-m), determined by calculation of reaction force in rated

deflection/deflection curve.

The performance value of fender shall take the mean value of the 2nd and 3rd testing result.

In the testing results, it is preferred that the energy absorption value shall be greater than the required

energy absorption value with 10% deducted, the reaction force value shall be lower than the required

reaction force value with 10% added.

Record the in-house temperature in the testing

BOLLARD

www.lexxonco.com57

Bollard Types and Selection

Double Bitt Bollard

Double Bitt Bollards are useful when high densities of mooring lines are

present. The two column design allows two lines to be secured and

independently released without having to compromise the mooring of an

adjacent vessel. The opposing sloping columns are particularly useful for

securing of spring lines as their greatest strength is parallel to the berth.

Kidney Bollard

Kidney Bollards offer an economical solution for installations where securing

of mooring lines at high angles is not a concern. This style is not

recommended when multiple mooring lines will share one bollard as there

may be a possibility of an unintentional release due to the shallow lip at the

top of the bollard.

T-head and Staghorn Bollard

While customer preference may determine the model supplied by Lexxon,

there are differences amongst models that should be considered when

selecting a bollard. T-head and Staghorn Bollards can handle higher line load

angles than Single Bitt and Kidney shaped bollards. This feature may be of

particular importance where very large changes in water level result in

significant differences in line angles. Large differences in line angles may

also occur at multipurpose berths where widely varying vessel sizes frequent

the same berth.

BOLLARD

58

Installation

Various options exist for the installation of mooring bollards. The most common method is utilizing cast-in-

place embedded anchors. Alternate methods include through bolting with cast in pipe sleeves, or epoxy-in

anchors for retrofitting existing structures. Cast-in anchors or pipe sleeves should be set in place with the aid of

a template or setting frame which will locate the anchors within the proper tolerances. For installations where

the bollard is to be set into a recess cast into the concrete, Lexxon can supply a unique solution whereby the

recess form work and anchor location template can be combined into one tool. Contact Lexxon for more

information or assistance with this technique. Always follow installation procedures supplied by Lexxon when

installing our bollards as each installation may be unique and require special instructions. Particular attention

should be paid to the torque values recommended for each installation.

Coatings

Coatings are an essential part of the system as it prevents excessive corrosion that can weaken a bollard. This

is particularly significant for cast steel bollards, which are less corrosion resistant than ductile iron bollards.

Virtually any coating requested can be applied, but some attention to the abrasion resistance of the coating

should given as the direct contact and movement of the mooring lines will result in accelerated wear of any

coating.Bollards can be supplied fully painted from our factory or with an easily removable rust preventative

primer that allows surface preparation and coating on-site after installation. Traditionally, cleats are supplied

hot dip galvanized, but can also be supplied painted if requested.
