Introduction

Within marine and offshore we offer a wide range of tested

and approved products and constructions specially developed

for marine and offshore. We offer competitive solutions within

e.g. fire, sound and thermal insulation and insulation of tech-

nical installations.

A dedicated team of specialists is daily working to optimize our

range of products and constructions. The development and

sale are taking place in close cooperation with the local Rock-

wool companies and a world wide net of agents and dealers.

One of our main tasks is to assist and guide our customers

with the right information and advice about our products,

constructions and the practical insulation work.

This manual combines all relevant information on marine and

offshore insulation and is designed to keep you updated on our

knowledge within the field.

We hope that you will find the Technical Guidelines useful in

your daily work and inspirational to your future work within

marine and offshore insulation.

In the Technical Guidelines you will find:

General information about standards and test methods

within marine and offshore.

Practical information and advice about insulation and

installation procedures. Detailed information about our range of products and

constructions, construction details for e.g. bulkhead, deck

and junctions.

Overall information about sound insulation and

measurements of our products.

Construction details within thermal and technical

insulation.

Overview of our product range and our certificates.

The recommendations in this manual should be seen as

guidelines only. It is of course important that the insulation

work is done according to the IMO rules and regulations from

national authorities and classification societies.

1 Bridge

At the bridge it is important to secure a

high level of fire protection and sound

insulation. See page 17-44 for A-constructions

See page 69-72 for floating floor

See page 79-83 for sound insulation

2 Corridors

Corridors are part of the emergency

escape routes on a vessel. The numbers

of horizontal fire zones passed by the

corridor determine the fire insulation

class.

See page 17-44 for A-constructions



3 Storage and tank rooms

In the boiler room, storage rooms and

tank rooms it is often important to insu-

late surfaces, boilers and pipes.

See page 65 for penetrations

See page 73-78 for technical insulation

4 Engine room

The engine room contains a lot of fire

risks so fire protection is essential. Theengine room is also source of high and

often disturbing noise. It is often filled

with pipes, tanks, containers and other

equipment where technical insulation

is required. It is important to have the

insulation protected so oil vapour does

not get into the insulation material.




See page 103 for surfaces

5 Control room

In the control room fire is to be held out

as long as possible as this is the last

place where all the technical equipment

can be controlled. The sound level needs

to be low, as engine crew has to spend a

lot of time here. It is moreover important

that no vapour gets to the machines and

computers and that the room has a rea-

sonable sound level.

See page 17-44 for A-constructions See page 79-85 for sound insulation


6 Disco

The discothque, cinema and bar areas

onboard cruise ships are big sources of

noise. It is important to have the rightsound insulation around these areas

towards the neighbouring areas.




7 Cabins

On board a passenger ship it is essential

to have the right insulation between the

cabins. It is crucial to have the needed

fire protection and it is getting more and

more important to have a high level of

sound and thermal insulation.




8 Stairways

The stairways are part of the emergency

escape routes on a vessel. The numbers

of vertical fire zones passed by the stair-

way determine the fire insulation class.


9 Galley

In the galley you always have a risk of

fire, as you have a mixture of heat and

flammable materials. In this case it is

also necessary to be aware of the facings

as you have oil vapour in the air.




10 Public area

The public area is requiring all kinds of

insulation, depending on the situation.


See page 64 for draught stoppers


See page 87-90 for thermal insulation


11 Offshore

On offshore applications you have more

or less the same conditions as on a ship.

Furthermore you have the risk of hydro-

carbon fire and need to protect people

and material from an HC fire.

Insulation in General

Fig. 1. Welding of pins to the plate (bulkhead/deck).

As first step the pins must be welded to the plate and stiffener.

Distance between pins should not exceed 300 mm. For fire rated con-

structions the position of pins must follow the official drawings.

Fig.3A. Using an electrical saw to cut large amounts of Rockwool

SeaRox products.

When cutting large quantities of SeaRox insulation it is recommended

to use an electrical saw. This will ensure a good and angular surface

that is easy to tighten against the next Slabs. 2-5 mm oversize

is recommended. The pieces of insulation should be min.150x150 mm.

Fig. 3C. Using a shear to cut Wired Mats

Wired Mats should be cut with a large shear. 2-5 mm oversize is

recommended. The pieces of insulation should be min. 150x150 mm.

Fig. 2. Painting of the plate.

To avoid corrosion the plate can afterwards be painted with anti

corrosion paint.

Fig. 3B. Using a Rockwool knife to cut Rockwool SeaRox Insulation

Rockwool SeaRox insulation can easily be cut with a Rockwool knife

or a similar sharp knife. When the Slabs are cut in 2-5 mm oversize

(depending on density) the optimal tension and tightness can be

obtained when fitting the wool. The pieces of insulation should be min.

150x150 mm

PREPARATION

CUTTING

The installation of insulation material can be done in different

ways. It is up to the insulation contractor to choose the best

way for each application. For fire rated constructions the

installation has to follow the official drawings according to

the fire test. Drawings can be found on our website,

www.rockwool-rti.com. In the following you will finda general description of the way the insulation work can be

done:

Fig. 6 Fixing the insulation

Fix washers on the pins in order to secure fixing of the insulation.

Alternative 1, fig. 4A. Insulation of stiffeners

Depending on the construction it is recommended to start with the

insulation of the stiffeners. First by filling out the space, behind the

stiffener, with SeaRox insulation. The insulation should fit exactly to

the profile structure. Afterwards insulate around the stiffener with the

required thickness of SeaRox insulation.

Alternative 2, fig. 4A. Insulation between stiffeners

Depending on the construction it can be easier to start with insulation

of the plate. Joints must be tight and no air gaps must be found. In

connection with solutions with more than one layer of insulation, the

joints should be staggered by min. 150 mm to ensure that no joints go

straight through both layers.

Alternative 1, fig. 5A. Insulation between stiffeners.

Insulate the plate between stiffeners with SeaRox insulation. Joints

must be tight and no air gaps must be found. In connection with solu-

tions with more than one layer of insulation, the joints should be stag-

gered by 150 mm to ensure that no joints go straight through

both layers.

Alternative 2, fig. 5A. Insulation of stiffeners

Insulate with SeaRox insulation around the stiffener. Fill out the space

behind the stiffener with SeaRox insulation, the insulation should fit

exactly to the profile structure.

Securing the product

When installing the insulation all pieces must be fit firmly with

minimum one pin approx 10 mm longer than the nominal thick-

ness of the insulation. On A-constructions the material has to be

fastened with spring washers.

Different pins

Steel pins are used for steel decks and bulkheads. The steel pins are

coated with copper for corrosion protection. Stainless steel pins with

aluminium tip are used for aluminium constructions. The pins are

normally 3 mm in diameter and can be aquired in different lengths.

Washers

The spring washers used to slide over the pins for securing the insula-

tion should be 38 mm in diameter and of corrosion protected material.

Securing H-constructions

On H-constructions it is some times required that the pins are approx

40 mm longer than the nominal thickness of the insulation and are

bent in different directions to ensure that the wool is secured.

The additional application of wire mesh is not needed when using new

SeaRox H-constructions because the wire mesh is already part of ourWired Mat. On H-constructions the material has to be fastened with

spring washers.

Covering the steel washers

The washer can be fit with a plastic cap to cover the steel tip and to

create a nice looking surface.

VAPOUR BARRIER

STORAGE AND STACKING

Max height

3 m

R

Using tape to ensure an airtight surface between two batts

All joints must be sealed with a tape width of 75-100 mm to ensure

an air tight surface. Make sure that there is no grease on the surface

before the tape is applied. Pins and washers should be taped.

Stacking of Rockwool SeaRox products

The products must not be stacked in heights of more than three

metres.

Do not sit on the Rockwool SeaRox material

The products must at all times during storage remain untouched

and must not be affected by any kind og treading, sitting or anyother similar kind of exposure.

Storage of Rockwool SeaRox insulation

The products must at all times be stored dry indoor in closed ware-

house facilities.

In rooms where vapour will enter the insulation as a reason of tem-

perature/ pressure differences, a vapour barrier is often a demand.

When water vapour is moving from the hot room towards colder

surfaces, it will often lead to problems with corrosion. If it is oil vapour

this will be collected in the wool and endanger the fire properties ofthe wool.

To close the surface on the Rockwool SeaRox products there are

several options e.g. reinforced alu foil:

All joints must be sealed with a tape width of 75-100 mm to ensure

an air tight surface.

Make sure that there is no grease, oil or dirt on the surface before

the tape is applied. This will cause the tape to come loose.

Make sure all holes in the surface are closed.

The surface must have a low flame spread approval if it is used

for marine applications.

In order to secure the right conditions for storage of Rockwool

marine and offshore products a special set has of conditions been

prepared, e.g. the products:

Must at all times be stored dry indoor in closed warehouse

facilities.

Must not be stacked in more than two layers when delivered

on pallets.

Must only be stored on the flat side when delivered in packages and

must not be stacked in heights of more than three metres.

Must at all times during storage remain untouched and must not be

affected by any kind of treading, sitting or any other similar kind of

exposure.

Must be transported in closed compartments, e.g. trailers, contain-

ers and other cargo holds in order to avoid exposure to weather

elements and/or condensation etc.

Choosing the Right Product

To find the correct product it is necessary to know which ap

plication it has to be used for e.g.:

Fire insulation

Sound insulation

Thermal insulation

Insulation of technical installations

Floating floor insulation

Panels

Insulation of sub-sea pipelines

Combinations e.g. fire and sound insulation

When the application is known, the requirements for product

characteristics need to be evaluated e.g.:

Fire properties

Sound properties

Thickness

Thermal conductivity

Mechanical strength

In some applications the weight could be of importance. In

such cases the lighter products can be chosen, but it is not

always the lightest solution that gives the best result. The light

products do not protect against noise in the same frequency

band as the more heavy products, so here it is necessary to

know what result is requested in the end.

All Rockwool SeaRox products have good fire properties,

but when using the products on ships or offshore rigs it is

necessary to choose the right product fulfilling the needed

fire rating.

Furthermore it can be relevant to evaluate the different so-

lutions with regard to the working and installation method.

Depending on the experience, the labour cost and the prioriti-

sation it might be relevant to include parameters as e.g.:

Easy handling

Less cutting

Fast installation

Labour intensity

0575/year

Rockwool Technical Insulation has a large number of certifica-

tes for the different products and applications from classifica-

tion companies based on fire tests made at IMO approved fire

institutes.

When choosing a product it is necessary to choose a product

that is approved by the classification company that has to ap-

prove the application/newbuilding in the end.

Some customers prefer to work with constructions based on

Slabs, securing easy handling of small size and fixed products,

others prefer to work with constructions based on Wired Mats.

For some customers it is important to have the best and most

safe solutions typically based on a two layer solution where

other customers tend to focus on easy and fast installation.

Finally, it is important to focus on the right documentation

such as:

Type approvals

Type certificates

When using Rockwool SeaRox insulation onboard a vessel

carrying an EEA flag make sure that the product has the MED

approval symbol (wheelmark).

It is important to make sure that the products and construc-

tions have the right approval needed in the specific project,

e.g. construction approval, non-

combustible approval and low flame spread approval.

Remember to check if the certificate is valid at the time where

the insulation plan is approved by the classification societies.

13


14/108

Regulations for Fire InsulationAccording to SOLAS

The requirements for materials and constructions to meet

specified standards of safety are normally prescribed by in-

ternational or national laws related to shipping and offshoreinstallations.

In addition to these regulations classification societies such

as Det Norske Veritas (DNV) and Lloyds Register of Shipping

(LRS) may have additional requirements.

Approvals and Certification

Suppliers of materials and constructions to the

marine and offshore industry must prove that their prod-

ucts, as a minimum, meet the statutory requirements.

The MED directive (EC Council Directive 96/98/EC - Marine

Equipment Directive) has replaced the previous approv-

als from the maritime authorities within EEA countries.

All products supplied to marine carrying EEA flag must be

subject to the MED directive.

MED-certificates are issued by

notified bodies accredited by an

EEA country. Approved products

bear the mark of conformity.

Classification societies issue type approval certificates stat-ing the permission to use specific materials and construc-

tions together with any relative restrictions.

If there are special circumstances or requirements for spe-

cial details, it may be required to obtain statements from

other authorities.

Approval Requirements

To satisfy the national authorities and classification socie-

ties, materials and constructions must be proven to complywith the national and international requirements. Tests

have to be done at internationally recognised test labora-

tories.

The tests have to be performed so that the materials or

products are exposed to a fire generated under controlled

conditions that simulate as closely as possible a worst case

scenario.

Test Requirements

There are several national and international requirements

regarding the use of materials on ships and offshore instal-lations. These classifications are required to prove combus-

tibility characteristics and include ignition properties, heat

release and development of toxic gases and smoke.

To prove that materials meet the required fire technical

classification, tests are carried out at recognised test

institutions according to standardised test methods.

Material Test Methods

Testing of materials fire resistance is done according to the

latest FTP code for non-combustibility and where a facing is

applied for low flame spread.

It is important to note that materials which meet the require-

ments for non-combustibility do not have to be tested for other

fire technical properties.

All Rockwool A- and H-constructions are tested according

to FTP-code. FTP-code is describing also the thickness of

the test specimen. The decision about the thickness of the

structural part is in responsibility of the ship designer and will

finally be approved by the responsible class society.

Construction Test Methods

Testing of a constructions fire resistance (decks, bulkheads,

structural steel, penetrations etc.) is normally carried out in a

standardised test furnace, where the construction specimen

is exposed to a fire according to a standardised time/tempera-

ture curve.

SOLAS, Chapter II-2, Regulation 5.3.1:

Use of non-combustible materials

Insulating materials shall be non-combustible,

except in cargo spaces, mail rooms, baggage

rooms and refrigerated compartments of service

spaces. Vapour barriers and adhesives used in

conjunction with insulation, as well as the

insulation of pipe fittings for cold service

systems, need not be of non-combustible

materials, but they shall be kept to the minimum

quantity practicable and their exposed surfaces

shall have low flame-spread characteristics.

14


15/108

Class B Fire Divisions

Class B fire divisions must be of non-combustible materials

and must prevent the propagation of flames for at least 30

minutes during a standard fire test.

The divisions must be insulated so that the average tem-

perature on the unexposed side of the division does not

exceed 140C above the initial temperature.

Furthermore, the temperature at any single point on the

unexposed side must not exceed 225C above the initial

temperature within the time limits.

Class A Fire Divisions

Class A fire divisions must be of non-combustible materials

and insulation materials must be fire tested at a recognised

institution. They must be sufficiently braced and must pre-

vent the propagation of flames and smoke for a minimum of

one hour during a standard fire test.

The divisions must be insulated so that the average temper-

ature on the unexposed side of the division does not exceed

140C above the initial temperature.

Furthermore, the temperature at any single point on the

unexposed side must not exceed 180C above the initial


Class H Fire Divisions

Class H fire divisions must be of non-combustible materials

and insulation materials must be fire tested at a recognized

institution. They must be sufficiently braced and must pre-

vent the propagation of flames and smoke for a minimum of

two hours during a standard fire test for a hydrocarbon fire.

The divisions must be insulated so that the average tem-

perature on the unexposed side of the division does not

exceed 140C above the initial temperature.

Furthermore, the temperature at any single point on theunexposed side must not exceed 180C above the initial

One layer solution

The construction is based on a solution where the

construction is made with one product in one layer.

This leads to faster installation.

Low construction weight

The construction is based on products with a low

density and/or low thickness which lead to low total

construction weight.

Fast installation

The construction is based on Mats which reduce

the cutting especially around stiffeners, and

consequently faster installation time.

Safe solution

The construction is based on a multiple, typical two

layer solution which results in more safe solutions

especially due to staggered joints.

Optimal sound properties

The construction is based on products with higher

density and/or more thickness which result in better

sound properties.

Easy handling

The construction is based on Slabs, where the small

size and fixed structure of the products give an easy

handling in respect to cutting and installation.

Rockwool Technical Insulation has made symbols for all

fire rated applications explaining the advantages with each

application:

General arrangement prior to testing - blast resistance

- class H

The regulatory requirements for the blast behaviour offire rated bulkheads are not normally well documented.

It is considered a general requirement that all parts of fire

divisions maintain the same fire and explosion resistance

and proof of this must be documented through physical

testing.

All the above tests were carried out without any significant damage to the insulation material.According to the Norwegian Fire Research Laboratory (SINTEF) a fire will not affect the fire integrity or stability of the insulation.

Due to the test methods used, SINTEF has assessed the above results to be conservative.

Rockwool, in association with SINTEF (NBL) in Norway, has performed extensive testing on H-rated Rockwool insulation systems,

using controlled gas explosions. The test results below refer to the same insulation construction with various types of wire mesh.

Stiffeners

Stiffener

Stiffener

Solas requires that the stiffeners must be insulated*. One way

is to insulate without filling the space behind the stiffeners.

In other situations the insulation can follow the shape of the

stiffener or the void behind the stiffener can be filled

out.

If the stiffener is more than 450 mm wide the insulation can

be stopped at 450 mm. The insulation of stiffeners should be

finally approved by local surveyor.

In most bulkhead and deck constructions stiffeners are used to secure the necessary strength in the construction. In order to

prevent heat transmission it is important to secure the right insulation. In general insulation of the stiffeners must follow the

official drawings as carried out in the fire tests.

When two plates are connected in a corner, the heat bridge should always be kept in mind when insulating. The structure

must have insulation so that heat transfer can not occur from one unexposed surface through the structure and onto another

unexposed surface. The heat must always go minimum 450 mm under the insulation before reaching an unexposed surface(acc. to SOLAS MSC/circ. 1120 annex reg. 9.3.4).

Bulkhead and Deck - Construction details

In connection with insulation it is important to pay special attention to the details related to junctions, corners etc. in order to avoid

potential heat bridges. Below you will find examples of construction details:

Connections between

A-60 and A-0 construc-

tions should be insulated

by adding a layer of

A-60 insulation on the

A-0 construction in a

minimum width of 450

mm. This is to minimize

the effect of the heatbridge.

Another alternative to insulate the heat bridge can be done

by installing min. 450 mm* of insulation on the other side

of the construction.

This will reduce thetransferred heat and

thereby minimise the risk

of self ignition inside the

connecting room.

Installation of Surface Steel Plate

A surface protection of sheet metal can be installed in

different ways, depending on the layout of the stiffeners and

the amount of insulation.

It is important to make the fixing in a way that minimises the

heat bridges and structural noise transmitted via the hull.

Corrugated Structural Steel

A-60 Fire Rated Constructions

In some projects the standard IMO structural core is replaced

with a light structural core consisting of a corrugated steelplate.

To ease the insulation Rockwool Technical Insulation has got

an assessment from DBI (Danish Fire Institute) which allows

insulation using our standard fire rated constructions without

filling out the corrugation.

The assessments are valid for A-60 fire rated constructions

as follows:

SeaRox WM 640, 75 mm, 1 layer

SeaRox WM 620, 45 mm, 2 layer

SeaRox SL 640, 30 mm, 2 layer

SeaRox SL 620, 60 mm, 1 layer

The assessment is provided under the following restrictions:

Products as described in test report

Structural core towards the fire

The height of the corrugation may not exceed 100 mm and

the thickness of the corrugated steel plating is not below

1.9 mm.

The joint between the corrugated steel sheets must be fully

welded to insure air tightness.

The corrugated steel structural core should not carry any

vertical load.

Draught Stoppers

Draught stoppers are used above ceilings to avoid the spread

of smoke and flames in case of fire. Normally the classifica-

tion companies request a B-0 fire insulation above the ceiling.This can be made from SeaRox WM 640 or SeaRox SL 620 after

request from the local surveyor or the customer.

Construction

SeaRox WM 640, min. 50 mm, with reinforced aluminium foil

or...

SeaRox SL 620, min. 60 mm, with reinforced aluminium foil.

SeaRox SL 620 must be covered with wire mesh. Insulation

fixed with 3 mm pins and secured with 38 mm washers.

Installation

Step 1: First the pins are welded vertically to the underside of

the deck in alignment with the required position of the

Draught Stopper.

Step 2:The pins are then bent 90 in a staggered pattern as

shown.

Step 3:The Rockwool product and wire mesh are then pushed

over the pins so that they protrude by a minimum of

25 mm. The insulation is secured by spring steel

washers.

Penetrations Penetrations through the Draught Stopper are simply made

by cutting out the shape of the penetrating items in the

Rockwool product, for example, pipes, HVAC ducts and cable

racks.

The cut edge of the Wired Mat must fit tightly to the edge of

the penetrating item and the slit in the insulation must be

stitched/taped back together using steel wire/alu tape.

This solution can be used for any type of penetration includ-

ing multiple penetrations.

Penetrations

Penetrations of fire protection

When pipes, ducts or other go through a bulkhead or deck

it is called a penetration. There are special rules regarding

insulation when the decks or bulkheads with fire class are

penetrated.

The pipe going through a fire classed structure must be

made of steel and must have a length of minimum 900

mm. IMO suggests to use min. 450 mm on each side of the

construction.

The min. 900 mm insulation must have the same insulation

class weight as the structure that is penetrated.

SOLAS, Chapter II-2, Regulation 9, sec 3:

The duct spool must be insulated with A-rated fire

insulation for a distance of either side of the bulkhead

or deck (L1 + L2 = 900 mm)

B-15 Extension

B-15 extension is used as a B-15 wall extension above the

ceiling. The B-15 extension prevents smoke and fire to spread

above the ceiling. The B-15 extension solution has passed aB-15 fire test with SeaRox SL 470, 25 mm which fulfils the IMO

demands.
