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 CorridorsCorridors 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.


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 roomThe engine room contains a lot of fire risks so fire protection is essential. The engine 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 17-44 for A-constructions See page 73-78 for technical insulation See page 79-83 for sound insulation 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 See page 103 for surfaces

6 Disco The discothque, cinema and bar areas onboard cruise ships are big sources of noise. It is important to have the right sound 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 StairwaysThe 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.

See page 17-44 for A-constructions

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 facingsas you have oil vapour in the air.

See page 17-44 for A-constructions See page 73-78 for technical insulation See page 103 for surfaces

10 Public areaThe public area is requiring all kinds of insulation, depending on the situation.

See page 17-44 for A-constructions See page 64 for draught stoppers See page 79-85 for sound insulation See page 87-90 for thermal insulation See page 103 for surfaces

11 OffshoreOn 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.

8Insulation 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 find a general description of the way the insulation work can be done:

9Fig. 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 productWhen 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 pinsSteel 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.

WashersThe 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-constructionsOn 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 our Wired Mat. On H-constructions the material has to be fastened with spring washers.

Covering the steel washersThe washer can be fit with a plastic cap to cover the steel tip and to create a nice looking surface.

Using tape to ensure an airtight surface between two battsAll 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 productsThe products must not be stacked in heights of more than three metres.

Do not sit on the Rockwool SeaRox materialThe products must at all times during storage remain untouched and must not be affected by any kind og treading, sitting or any other similar kind of exposure.

Storage of Rockwool SeaRox insulationThe 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 of the 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.

Calculation of Materials

Below you will find a rough guidance for estimated need of material. Check your drawings for more detailed calculations.

INSULATION

IN GENERAL THE CUSTOMER IS ALWAYS RESPONSIBLE FOR CALCULATIONS

PINS AND WASHERS

TAPE WASTE

Based on a total amount of insulation for plate + stiffeners:

The plate equals 60%. The stiffeners equals 40%

Alternatively the use of pins and washers can be calculated by the total area of plate and stiffener in m2 times min. 18.

Example:A total quantity of 100 m2 plate needs to be in-sulated; also taking the insulation of stiffeners into consideration. Estimated need of pins and washers: 100 m2 x 18 pins/m2 = 1800 pins

As guidance the following amount of waste has to be included:

Insulation area < 100 m2 10% waste

Insulation area > 100 m2 5% waste

Based on a plate of X m2: The amount of Slabs for stiffeners can as guidance be calculated as X times 0.7

Example: of plate needs to be insulated.

Calculation of material for stiffener: 100 m x 0.7 = 70 m2

As guidance the use of pins and washers can be calculated as follows: Plate in m2 times min. 12. Stiffener in m2 times min. 10.

Example: insulation of plate requires x 12 pins/m2 = 1200 pins

100 m insulation of stiffeners requires 100 m2 x 10 pins/m2 = 1000 pins

As guidance the amount of tape for joints can be calculated by the insulated in m2 times 4 stated in running metres

Example:Tape for 100 m2 of insulation; 100 m2 x 4 m/m2 = 400 metres

Choosing the Right Product

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

Regulations for Fire Insulation According 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 offshore installations.

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 comply with 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 MethodsTesting 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 materialsInsulating 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

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.


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.


Notified BodyRockwool Technical Insulation is certified according to the MED directive. As notified body we have chosen Det Norske Veritas which also guaranties our quality by running audits.

One layer solutionThe construction is based on a solution where the construction is made with one product in one layer. This leads to faster installation.

Low construction weightThe construction is based on products with a low density and/or low thickness which lead to low total construction weight.

Fast installationThe construction is based on Mats which reduce the cutting especially around stiffeners, and consequently faster installation time.

Safe solutionThe construction is based on a multiple, typical two layer solution which results in more safe solutions especially due to staggered joints.

Optimal sound propertiesThe construction is based on products with higher density and/or more thickness which result in better sound properties.

Easy handlingThe 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 of fire 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.

General arrangement after testing - recommended design limits

SeaRox SL 660 with heavy duty stainless mesh and bent pins: Peak overpressure: 0.7 bar Duration (positive phase): 35 ms Explosion wind: 300 m/s

Galvanised mesh and bent pins: Peak overpressure: 0.6 bar Duration (positive phase) 35 ms Explosion wind: 300 m/s

Galvanised mesh and standard pins: Peak overpressure: 0.4 bar Duration (positive phase): 50 ms Explosion wind: 300 m/s

Strength of covering steel plate must be calculated by designer

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.

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 detailsIn 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 heat bridge.

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 the transferred 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 ConstructionsIn some projects the standard IMO structural core is replaced with a light structural core consisting of a corrugated steel plate.

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.

InstallationStep 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 protectionWhen 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)

Fire Protection of Sprinkler Pipes

New amendment to SOLAS regulation about protection of sprinkler pipes on passenger vessels Seen in the light of the increasing sizes of passenger ships and growing number of passengers, an amendment to SOLAS regulation Safe return to port is applicable to all passenger ships built on or after 1st July 2010 stating that sprinkler pipes on passenger vessels need to remain operational in case of fire.

The amendment is valid for:

All passenger ships of 120 m or more, or...

Having three or more main vertical zones

Applicable also for ROPAX vessels and large offshore accommodations.

Floating Floor Constructions Class A-60

MED-B-7488 includes two different types of A-60 Deck class Floating Floor constructions.

1) SeaRox SL 480This solution consists of two layers SeaRox SL 480, each of 30 mm thickness, covered by minimum 2 mm steel plate, spot welded at c/c 150 mm.

This construction combines the excellent properties of fire protection, noise reduction, high compression strength and thermal insulation.

The max free area recommended is 8 x 8 m. If larger free areas are to be made, division flat bars should be made. This allows the insulation to stay in position without the need of gluing. It is recommended to make full overlap of the two layers. All joints of the Slabs have to be tight butted joints. Smaller weld marks, dents, etc. of an approx max diameter of 50 mm and 10 mm height will be absorbed.

If the deck is undulating, an approved self levelling compound or floor screed will have to be used as first layer; a fire retard-ant PE compound, cement based filler or similar. If a water based floor screed or levelling compound is used, it must be given sufficient time to cure before the floating construction is installed. It is very important to ensure not to encapsulate water/moisture, as this will enhance corrosion and limit the expected life time of the construction.

Min. 2 mm Steel Top Plate

30 mm

30 mm

SeaRox SL 480, 2 layersSteel Deck Plate

The top layer has to be made of minimum one layer of 2 mm steel plate, according to the fire approvals.

Final floor covering has to be decided based upon require-ments for mechanical strength and floor finish.

As flooring solution, this one is a safe solution, in the sense that a SeaRox SL 480 of 200 kg/m3 is very ridged and strong, and combined with a medium thick steel plate this is normally adequate for all normal accommodation load up to 40 kN/m2.

71

2) SeaRox SL 436This solution consists of one layer of SeaRox SL 436, 60 mm thickness, covered by minimum 1.5 + 3 mm steel plate. The construction gives in addition to the excellent properties of fire protection, noise reduction and thermal insulation, also reduc-tion of structural noise/vibrations in the steel deck.
