Bridge

At the bridge it is important to secure a high level of fi re protection and sound insulation.

See page 15-40 for A-constructions See page 63-66 for ﬂ oating ﬂ oor See page 73-76 for sound insulation

Storage and tank rooms

In the boiler room, storage rooms and tank rooms it is often important to insulate surfaces, boilers and pipes.

See page 61 for penetrations See page 67-72 for technical insulation

Cabins

On board a passenger ship it is essential to have the right insulation between the cabins. It is crucial to have the needed fi re protection and it is getting more and more important to have a high level of sound and thermal insulation. See page 15-40 for A-constructions See page 73-76 for sound insulation See page 77-80 for thermal insulation

Disco

The discothèque, 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. See page 15-40 for A-constructions See page 63-66 ﬂ oating ﬂ oor See page 73-76 for sound insulation

Corridors

Corridors are part of the emergency escape routes on a vessel. The numbers of horizontal fi re zones passed by the corridor determine the fi re insulation class.

(5)

4 55 Marine & Of fshor e Insulation - an overview Engine room

The engine room contains a lot of fi re risks so fi re protection is essential. The engine room is also source of high and often disturbing noise. It is often fi lled 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 15-40 for A-constructions See page 67-72 for technical insulation See page 73-76 for sound insulation See page 93 for surfaces

Offshore

On offshore applications you have more or less the same conditions as on a ship. Furthermore you have the risk of hydrocarbon fi re and need to protect people and material from an HC fi re. See page 41-50 for H-constructions

See page 51-54 for Jet Fire and Blast Resistance

Public area

The public area is requiring all kinds of insulation, depending on the situation. See page 15-40 for A-constructions See page 60 for draught stoppers See page 73-76 for sound insulation See page 77-80 for thermal insulation See page 93 for surfaces

Stairways

The stairways are part of the emergency escape routes on a vessel. The numbers of vertical fi re zones passed by the stair-way determine the fi re insulation class. See page 15-40 for A-constructions

Galley

In the galley you always have a risk of fi re, as you have a mixture of heat and ﬂ am-mable materials. In this case it is also necessary to be aware of the facings as you have oil vapour in the air.

See page 15-40 for A-constructions See page 67-72 for technical insulation See page 93 for surfaces

Control room

In the control room fi re 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 reasonable sound level. See page 15-40 for A-constructions See page 73-76 for sound insulation See page 93 for surfaces

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

As fi rst step the pins must be welded to the plate and stiffener. Distance between pins should not exceed 300 mm. For fi re rated constructions the position of pins must follow the offi cial drawings.

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

When cutting large quantities of Rockwool 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 Batts/Slabs. 2-5 mm oversize is recom-mended. 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 Insulation

Rockwool insulation can easily be cut with a Rockwool knife or a similar sharp knife. When the Batts/Slabs are cut in 2-5 mm oversize (depending on density) the optimal tension and tightness can be obtained when fi tting the wool. The pieces of insulation should be

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 fi re rated constructions the installation has to follow the offi cial drawings according to the fi re test. Drawings can be found on our website, www.rockwool-marine. com. In the following you will fi nd a general descrip-tion of the way the insuladescrip-tion work can be done:

Fig. 6 Fixing the insulation

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

Alternative 1, fi g. 4A. Insulation of stiffeners

Depending on the construction it is recommended to start with the insulation of the stiffeners. First by fi lling out the space, behind the stiffener, with Rockwool insulation. The insulation should fi t exactly to the profi le structure. Afterwards insulate around the stiffener with the required thickness of Rockwool insulation.

Alternative 2, fi g. 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, fi g. 5A. Insulation between stiffeners

Insulate the plate between stiffeners with Rockwool insulation. 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 150 mm to ensure that no joints go straight through both layers.

Alternative 2, fi g. 5A. Insulation of stiffeners

Insulate with Rockwool insulation around the stiffener. Fill out the space behind the stiffener with Rockwool insulation, the insulation should fi t exactly to the profi le structure.

General

Securing the product

When installing the insulation all pieces must be fi t fi rmly with mini-mum one pin approx 10 mm longer than the nominal thickness 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 insulation should be 38 mm in diameter and of corrosion protected material.

Securing H-constructions

On H-constructions it is recommended 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. In case of H-constructions use of wire mesh as a cover is recommended. On H-constructions the material has to be fastened with spring washers.

Covering the steel washers

The washer can be fi t with a plastic cap to cover the steel tip and to create a nice looking surface.

Insulation

in

General

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 products

The products must not be stacked in more than two layers when delivered on pallets. They must only be stored on the ﬂ at side when delivered in packages and must not be stacked in heights of more than three metres. It is recommended that roll products are stacked upright.

Do not sit on the Rockwool material

The 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 insulation

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

STORAGE AND STACKING

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 fi re properties of the wool.

To close the surface on the Rockwool 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 ﬂ ame spread approval if it is used for marine applications.

In order to secure the right conditions for storage of Rockwool Marine & Offshore products a special set of conditions have 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 ﬂ at 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 fi nd a rough guidance for estimated need of material. Check your drawings for more detailed calculations.

INSULATION

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 wash-ers 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 insulated; also taking the insulation of stiffeners into consideration. Estimated need of pins and washers: 100 m2_{x 18 pins/m}2_{= 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}

Calculation

of

Materials

Based on a plate of X m2_{. The amount} of Batts/Slabs for stiffeners can as guidance be calculated as X times 0.7

Example:

100 m2_{of plate needs to be insulated.} Calculation of material for stiffener: 100 m2_{x 0.7 = 70 m}2

1

2

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:

100 m2_{insulation of plate requires} 100 m2_{x 12 pins/m}2_{= 1200 pins} 100 m2_{insulation of stiffeners requires} 100 m2_{x 10 pins/m}2_{= 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/m}2_{= 400 metres}

Choosing the Right Product

To fi nd 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 ﬂ oor insulation

• Panels

• Insulation of sub-sea pipelines

• Combinations e.g. ﬁ re 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 impor-tance. 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 products have good fi re properties, but when using the products on ships or offshore rigs it is necessary to choose the right product fulfi lling the needed fi re rating.

Furthermore it can be relevant to evaluate the differ-ent solutions with regard to the working and instal-lation method. Depending on the experience, the labour cost and the prioritisation it might be relevant to include parameters as e.g.:

• Easy handling • Less cutting • Fast installation • Labour intensity

0575/year

Rockwool Marine & Offshore has a large number of certifi cates for the different products and applica-tions from classifi cation companies based on fi re tests made at IMO approved fi re institutes.

When choosing a product it is necessary to choose a product that is approved by the classifi cation com-pany that has to approve the application/newbuilding in the end.

Some customers prefer to work with constructions based on Batts, securing easy handling of small size and fi xed products, others prefer to work with con-structions based on Wired Mat. 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 certiﬁ cates

When using Rockwool insulation onboard a vessel carrying an EEA fl ag make sure that the product has the MED approval symbol (wheelmark).

It is important to make sure that the products and constructions have the right approval needed in the specifi c project, e.g. construction approval, non-combustible approval and low fl ame spread approval. Remember to check if the certifi cate is valid at the time where the insulation plan is approved by the classifi cation societies.

Requir ements for Fir e Insulation

Regulations for Fire Insulation

According to SOLAS

The requirements for materials and construc-tions to meet specifi ed standards of safety are normally prescribed by international or national laws related to shipping and offshore installa-tions.

In addition to these regulations classifi cation societies such as Det Norske Veritas (DNV) and Lloyds Register of Shipping (LRS) may have ad-ditional requirements.

Approvals and Certifi cation

• Suppliers of materials and constructions to the marine and offshore industry must prove that their products, as a minimum, meet the statutory require-ments.

• The MED directive (EC Council Directive 96/98/ EC - Marine Equipment Directive) has replaced the previous approvals from the maritime authori-ties within EEA countries. All products supplied to marine carrying EEA fl ag must be subject to the MED directive.

• MED-certifi cates are issued by notifi ed bodies accredited by an EEA country. Approved products bear the mark of conformity.

• Classifi cation societies issue type approval certifi -cates stating the permission to use specifi c mate-rials and constructions together with any relative restrictions.

• If there are special circumstances or requirements for special details, it may be required to obtain statements from other authorities.

Approval Requirements

• To satisfy the national authorities and classifi ca-tion societies, materials and construcca-tions must be proven to comply with the national and international requirements. Tests have to been done at interna-tionally recognised test laboratories.

• The tests have to be performed so that the materials or products are exposed to a fi re generated under controlled conditions that simulate as closely as pos-sible a worst case scenario.

Test Requirements

• There are several national and international require-ments regarding the use of materials on ships and offshore installations. These classifi cations are required to prove combustibility characteristics and include ignition properties, heat release and devel-opment of toxic gases and smoke.

• To prove that materials meet the required fi re technical classifi cation, tests are carried out at recognised test institutions according to standard-ised test methods.

Material Test Methods.

Testing of material’s fi re resistance is done according to FTP code for non-combustibility and where a facing is applied for low fl ame spread. The most com-monly accepted test methods are:

• Non-Combustibility: IMO A-799(19) ISO 1182

• Low Flame Spread: IMO A-653(16)

It is important to note that materials which meet the requirements for non-combustibility do not have to be tested for other fi re technical properties.

Construction Test Methods

Testing of a construction’s fi re resistance (decks, bulk-heads, structural steel, penetrations etc.) is normally carried out in a standardised test furnace, where the construction specimen is exposed to a fi re according to a standardised time/temperature curve.

The most common test methods are:

• Recommendation on Fire Test Procedures for “A”, “B” and “F” Class Divisions. IMO A-754 (18)

§

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 fi ttings 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 fl ame-spread characteristics.”

(13)

12 13 Requir ements for Fir e Insulation

Class B Fire Divisions

• Class B ﬁ re divisions must be of non-combustible materials and must prevent the propagation of ﬂ ames for at least 30 minutes during a standard fi re test.

• The divisions must be insulated so that the average temperature on the unexposed side of the division does not exceed 140°C above the initial temperature.

• Furthermore, the temperature at any single point on the unexposed side must not exceed 225°C above the initial temperature within the time limits.

Class A Fire Divisions

• Class A ﬁ re divisions must be of non-combustible materials and insulation materials must be fi re tested at a recognised institution. They must be suffi ciently braced and must prevent the propagation of ﬂ ames and smoke for a minimum of one hour during a standard fi re test.

• The divisions must be insulated so that the average temperature on the unexposed side of the division does not exceed 140°C above the initial temperature.

Class H Fire Divisions

• Class H ﬁ re divisions must be of non-combustible materials and insulation materials must be fi re tested at a recognized institution.

Guide

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 Batts, where the small size and fi xed structure of the products give an easy handling in respect to cutting and installation. SYMBOL GUIDE
