BridgeAt the bridge it is important to secure a high level of fi re protection and sound insulation.See page 15-40 for A-constructionsSee page 63-66 for fl oating fl oorSee page 73-76 for sound insulation

Storage and tank roomsIn the boiler room, storage rooms and tank rooms it is often important to insulate surfaces, boilers and pipes. See page 61 for penetrationsSee page 67-72 for technical insulation

CabinsOn 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-constructionsSee page 73-76 for sound insulationSee page 77-80 for thermal insulation

DiscoThe 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-constructionsSee page 63-66 fl oating fl oorSee page 73-76 for sound insulation

CorridorsCorridors 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. See page 15-40 for A-constructions

Engine roomThe 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-constructionsSee page 67-72 for technical insulationSee page 73-76 for sound insulationSee page 93 for surfaces

OffshoreOn 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-constructionsSee page 51-54 for Jet Fire and Blast Resistance

Public areaThe public area is requiring all kinds of insulation, depending on the situation.See page 15-40 for A-constructionsSee page 60 for draught stoppersSee page 73-76 for sound insulationSee page 77-80 for thermal insulationSee page 93 for surfaces

StairwaysThe 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

GalleyIn 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-constructionsSee page 67-72 for technical insulationSee page 93 for surfaces

Control roomIn 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-constructionsSee page 73-76 for sound insulationSee 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 productsWhen 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 MatsWired 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 plateTo avoid corrosion the plate can afterwards be painted with anti corrosion paint.

Fig. 3B. Using a Rockwool knife to cut Rockwool InsulationRockwool 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 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 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 insulation work can be done:

Alternative 1, fi g. 4A. Insulation of stiffenersDepending 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 stiffenersDepending 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 stiffenersInsulate 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.

Securing the productWhen 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 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 insulation should be 38 mm in diameter and of corrosion protected material.

Securing H-constructionsOn 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 washersThe washer can be fi t 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 productsThe 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 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 insulationThe 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

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 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/m2 = 1800 pins

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

Insulation area < 100 m2 10 % wasteInsulation area > 100 m2 5% waste

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 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: 100 m2 insulation of plate requires 100 m2 x 12 pins/m2 = 1200 pins 100 m2 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 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.

tion 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 constructions 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 MethodsTesting 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 � 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 � ame-spread characteristics.”

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.



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. They must be suffi ciently braced and must prevent the propagation of fl ames and smoke for a minimum of two hours during a standard fi re test for a hydrocarbon fi re.

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

rs Stiffeners

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 theinsulation can be stopped at 450 mm.

ionsBulkhead and Deck Connections

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 constructions should be insulated by adding a layer of A-60 insu-lation 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 mini-mise the risk of self ignition inside the connecting room.

Draught Stoppers

Draught stoppers are used above ceilings to avoid the spread of smoke and fl ames in case of fi re. Normally the classifi cation companies request a B-0 fi re insula-tion above the ceiling. This can be made from Rock-wool Marine Wired Mat or Rockwool Marine Batts after request from the local surveyor or the customer. Construction• Rockwool Marine Wired Mat 105, min. 50 mm,

with reinforced aluminium foil or Rockwool Marine Firebatts 100, min. 60 mm, with reinforced aluminium foil.

• Marine Firebatts 100 must be covered with wire

mesh. Insulation fi xed with ø3 mm pins and secured with ø38 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 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 thepenetrating items in the Rockwool, for example, pipes, HVAC ducts and cable racks.

• The cut edge of the Wired Mat must fi t tightly to the

edge of the penetrating item and the slit in theRockwool must be stitched/taped back together using steel wire/alu tape.

• This solution can be used for any type of

penetration including multiple penetrations.

Floating Floor Constructions Class A-60

MED-B-2302 includes two different types of A-60 Deck class Floating Floor constructions.

1) Rockwool Marine Slab 200This solution consists of two layers Rockwool Marine Slab 200, each of 30 mm thickness, covered by mini-mum 2 mm steel plate, spot welded at c/c 150 mm.

This construction combines the excellent properties of fi re 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 fl at bars should be made. This allows the insulation to stay in posi-tion without the need of gluing. It is recommended to make full overlap of the two layers. All joints of the Marine 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 fl oor screed will have to be used as fi rst layer; a fi re retardant PE compound, cement based fi ller or similar. If a water based fl oor screed or levelling compound is used, it must be given suffi -cient time to cure before the fl oating construction is installed. It is very important to ensure not to encap-sulate water/moisture, as this will enhance corrosion and limit the expected life time of the construction.

64

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

Final fl oor covering has to be decided based upon requirements for mechanical strength and fl oor fi nish.

As fl ooring solution, this one is a “safe” solution, in the sense that a Rockwool Marine Slab 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.

2) Marine Slab 140This solution consists of one layer of Rockwool Marine Slab 140, 60 mm thickness, covered by minimum 1.5 + 3 mm steel plate. The construction gives in addition to the excellent properties of fi re protection, noise reduction and thermal insulation, also reduction of structural noise/vibrations in the steel deck. Rockwool Slab 140 has been designed with focus on the dynamic stiffness, i.e. best possible noise reduc-tion. Please note that the compression strength of this solution is lower than the Marine Slab 200 solution.

The fi rst layer of steel plate must be 1.5 mm thick, installed with 50 mm overlap and secured with pop rivets. The second layer(top layer) must be 3 mm steel plate with butted joints and spot welded at c/c 150 mm. Top covering has to be decided based upon requirements for mechanical strength and fi nish.

65

Rockwool Marine & Offshore is preferred supplier for many marine fl ooring companies. These companies integrate the Rockwool prod-ucts in their more sophisticated solutions.

Sealing of edges to prevent structural noise

Enclosing:For the perimeter of the construction it is recom-mended to fi nish the insulation with a rigid Rockwool product i.e. Rockwool Marine Slab 140 or 200 placed edgeways and sealed with a fl exible sealant.

Many of the fl ooring companies are using Rockwool Marine Slabs in densities of 140 - 200 kg/m3, in com-bination with more complex top layers. The max load for the complete fl ooring construction will depend entirely on the top layer. The load capacity of the spe-cifi c construction is to be calculated and tested by the fl ooring company.

Rockwool Marine & Offshore is preferred supplier for many dedicated marine fl ooring companies. These companies then create more sophisticated solutions for superb noise reduction in both high and low fre-quencies.

Note: Deviations from the certifi ed A-60 fl oating fl oor construction in any form, could require new approval by the Class Society or National Marine Authority.

Principally, a thermal insulation structure for piping consists of an appropriate insulating material, usually covered by sheet metal cladding. This protects the pipe and the insulation from external infl uences such as weather or mechanical loads.

Spacers are also essential with insulation material such as wired mats, which do not offer suffi cient re-sistance to pressure to hold the weight of the cladding and other external loads. These spacers transfer the loads from the cladding directly onto the pipe to be insulated. In case of vertical piping, support struc-tures are fi tted to take on the loads of the insulation and the cladding. In general, support structures and spacers form thermal bridges.

HVAC Insulation - PipesFor the HVAC (Heat Ventilation Air Condition) appli-cations onboard a ship it is most common to use Pipe Sections or Marine Lamella Mats to insulate the pipes. The aim is to prevent heat loss in heating systems and warm water supply. It is necessary to supply heating and warm water also in the last cabin away from the source.

AirductsToday, many requirements are made on air ducts. Most important is that the comfort on board the ves-sels or platform living quarters is considered and that no compromises are made to the demands on fi re safety. In connection with ventilation of cabins and other rooms it must furthermore be ensured that no condensation is formed and that the required tem-perature is maintained all the time. This is obtained by using one of the Rockwool Marine & Offshore prod-ucts in the correct thickness. Thickness calculation program can be found on our webpage.

To guarantee a correct process cycle, the condition of the media within the pipes must remain within the set limita-tions (e.g. temperature, viscosity, pressure, etc.). In addition to the correct isometric construction and fastening of the piping, the piping insulation also has an important function. It must ensure that heat losses are effectively reduced and that the installation continues to operate economically and functionally on a permanent basis. This is the only way to guarantee the maximum effi ciency of the process cycle throughout the design service life without losses as a result of faults.

The benefi ts of correct thermal The benefi ts of correct thermal insulation for piping include:insulation for piping include:

• Reduction of heat losses• Cost savings • Reduction of CO2 emissions emissions• Frost protection • Process control:

Multiple Layers

• Where there is a requirement for more than one layer of Pipe Section, it is recommended that both layers should be banded to ensure a consistently tight fi t of the insulation.

• The outer layer(s) of the section should be applied

with staggered joints, both laterally and longitudi-nally.

Insulation with Pipe Section

• Generally, the best insulation is achieved by using Rockwool Pipe Section. The Pipe Sections can be used up to max. service temperatures of 620°C acc. to EN 14707. Facing max. 80°C. The Pipe Sections are supplied ready split and hinged for quick and easy snap-on assembly and are suitable for thermal and acoustical insulation of pipe work.

• Their excellent fi t and high compression resistance mean that Pipe Sections can be applied in a single layer without any additional spacers. Consequently the number of thermal bridges, which have a nega-tive infl uence on the insulation, is greatly reduced.

Banding • Rockwool recommends that the Pipe Section is se-

cured to the pipe by applying three steel bands per section length, with the end bands approximately 100mm from the lateral joints.

• If wire ties or spiral binding are to be used, they

should only be considered on pipe sections with an outer surface diameter of 200 mm or less.

In those cases, there should be:• At least three wires tie per section.• Spiral binding must be per section

(i.e. tied off at each end of each pipe section).

• Marine Lamella Mat 32 consists of stone wool lamel-las placed edgewise, the majority of the fi bres be-ing perpendicular to the facing. The Marine Lamella Mats can be used up to max. service temperatures of 250°C. Facing max. 80°C.

• Due to the alignment of the Rockwool fi bres in Marine Lamella Mats, they have a high resistance to compression. They are suitable for applications where there is a requirement for:

• Compression resistance

• Possible mechanical impact

• Operational vibration loads

• The surface fi nish on the Marine Lamella Mats,

should be taped at all joints. • The mats are secured with steel banding.

Elbows/Bends

• To form insulated elbows with Pipe Section, the section is cut at angles to form segments.

• The amount of segments depends on the size of the

pipe and the angle of the elbow. • When the pipe section segments are fi t around the

pipe, they are secured with steel banding or wire ties per section.

• Any minor gaps between segments can be fi lled

with pieces of Rockwool insulation.

Insulation with Marine Lamella Mat

70 7171

• Marine Wired Mat is a lightly bonded stone wool mat faced with a galvanised wire mesh. The Wired Mats can be used up to max. service temperatures of 680°C acc. to EN 14706. Facing 80°C.

• Due to their fl exibility and high temperature resist-ance, Marine Wired Mats can easily be cut and fi xed onto the piping.

• Marine Wired Mats have a relatively low resist-ance to pressure and from a practical point of view should only be installed in combination with spac-ers. Due to the thermal bridges of this combina-tion the better insulation performances are often achieved in the lower and middle temperature range with Marine Pipe Sections rather than with Marine Wired Mats.

Fixing

• Any gaps created by the type of support ring installed, must be fi lled with loose Rockwool.

• The Marine Wired Mats are secured to the pipe by

stitching the edges of the wire mesh together with binding wire or by clipping the mesh together with C-Hooks.

• On pipes with a diameter greater than 350 mm,

steel straps or additional pins and spring washers are applied on the underside of the pipe, it may be necessary to prevent sagging.

• On vertical pipes, the wire mesh of each mat must

be tied to the support ring above.

Multiple Layers • Where there is a requirement for more than one

layer of Marine Wired Mat, it is recommended that all layers are stitched or clipped to ensure a consist-ently tight fi t of the insulation.

• The outer layer(s) of mat should be applied with

longitudinally staggered joints and where applicable, with staggered joints laterally.

These wired mats are ideal for application in situations where the use of Pipe Sections is diffi cult or impossible:

• Temperatures above 300°C

• Pipe diameters ≥ ø350 mm

• Piping with a high number of shaped pieces such as elbows or T-joints.

Insulation with Marine Wired Mat

Cladding

Suitable cladding should be applied to protect the insulation from weather infl uences, mechanical loads and (potentially corrosive) pollution. Selecting the ap-propriate cladding depends on various factors, such as working loads, wind loads, ambient temperatures and conditions.

When selecting the appropriate cladding, take the following points into account:

• As a general rule, galvanised steel more than aluminium is used indoors due to its mechanical strength, fi re resistance and low surface tempera-ture (in comparison to an aluminium cladding).

• In corrosive environments like outdoors on deck where salty water leads to corrision, aluminised steel, stainless steel or glass reinforced polyester (e.g. Rocktight) is used as cladding. Stainless steel is recommended for use in environments with a fi re risk.

• The surface temperature of the cladding is infl u-enced by the material type. The following applies as a general rule: the shinier the surface, the higher the surface temperature.

• To exclude the risk of galvanic corrosion, only use combinations of metals that do not tend to corrode due to their electrochemical potentials.

• For acoustic insulation, a noise absorbent mate-rial (Lead layer, polyethyten foil) is installed on the insulation or inside the cladding. To reduce the risk of fi re, limit the surface temperatures of the cladding to the maximum operating temperature of the noise absorbent material.

• Tanks and vessels can be insulated with Rockwool Marine Slabs/Batts min. density 45 kg/m3 if there are no requirements for high operational temperatures. The products can be used up to max. service tem-peratures of 250°C.

• The Marine Slabs/Batts are installed over metal strap ties. These ties are bent over the edge of the outer layer of Marine Slabs/Batts to retain them against the tank wall.

• Where the insulation extends more than 4 m in

height, intermediate support profi les must be installed onto the tank wall. Special “S”-profi les can be used to ensure vertically staggered joints, while supporting the Marine Slabs/Batts above and retain-ing the Marine Slabs/Batts below.

• When more than one layer of Marine Slabs/Batts is

required, all joints must be staggered and tightly butted together to avoid thermal bridges.

• The Marine Slabs/Batts must be covered with a fl at

or profi led external cladding to protect them from the weather and mechanical damage.

Rules and Regulations

In general for commercial vessels the rules concern-ing noise levels onboard are quite simple and few. It is basically a set of dB(A) levels given for a range of different positions onboard. These settings are given in the IMO res. A.468(XII).

Limits for noise levels are specified for various maximum spaces as follows:

Work spaces dB(A)

Machinery spaces (continuously manned) 90

Machinery spaces (not continuously manned) 110

Machinery control rooms 75

Workshops 85

Non-specified work spaces 90

Navigation spaces dB(A)

Navigating bridge and chart rooms 65

Listening posts, including navigating bridge wings and windows 70

Radio rooms (with radio equipment operating but not producing audio signals) 60

Radar rooms 65

Accommodation spaces dB(A)

Cabins and hospitals 60

Mess rooms 65

Recreation rooms 65

Open recreation areas 75

Offices 65

Service spaces dB(A)

Galleys, without food processing equipment operating 75

Service and pantries 75

Normally unoccupied spaces dB(A)

Spaces not specified 90

Sound

When the sound hits a wall, the sound is reflected - some will be absorbed and a small part will be transmitted.

The sound insulating property of the construction, its reduction power called R, is measured in dB and is a measurement of the power of the construction to prevent the passage of the sound.

High R = good sound insulation = good sound reduction.

In porous absorbers like Rockwool materials the sound absorption takes place by the sound energy being converted into frictional heat between the Rockwool fibres. The sound absorption depends on the thickness of the material. The values at the low frequencies are improved with increased thickness. The same tendency can be obtained by moving the absorbers away from the base.

Protection of the absorber by a cover plate does not change the absorption as long as the plate has a suffi-cient number of openings. A perforation of 15% could be sufficient for a 1 mm thick cover plate of steel.Thicker covers require a larger number of small holes.

Overview - absorption measurements

Sound absorption is a material property which describes how well sound waves are absorbed in a material. When a sound wave is absorbed, it simply means that the sound wave is transferred into another kind of energy i.e. heat. On this page you will fi nd the sound absorption coeffi cient, αw for the most com-mon Rockwool Marine & Offshore products.

Sound Absorption

76

Sound reduction is an impression rating the reduction of sound through a wall or a building element from one room to the other. Since the sound reduction may be different at different frequencies, test measure-ments are subjected to a standard procedure which yields a single number that is about equal to the average sound reduction in the middle of the human hearing range. The weighting procedure is standard-ized in ISO 717-1 for the sound reduction of airborne noise.

Rw , R’w: weighted sound reduction index, dB

R’w (dB) is the weighted apparent sound reduction

index in a building, including fl anking sound trans-mission. R

w is the laboratory value for the weighted

sound reduction without fl anking transmission.

Thermal Calculations page 80

78

The requirements of the indoor climate and comfort have become more stringent during the recent years. The insulation constitutes an important factor of this, as it ensures that the correct temperature is obtained.

The most common way of expressing thermal prop-erties is by using the following nomenclature:

• Coeffi cient of the Thermal Transmission (U-value)

• Thermal Resistance (R)

• Thermal Conductivity (λ)

It is important to note that the λ-value for any given material varies with temperature. Specifi cation of the λ-value should therefore be referred to as “mean” temperature and, if possible, to a standardised method for measurement and calcula-tion.

Solutions for Thermal Insulation

1: Thermal insulation can be used alone where there is no other demand for the deck and bulkhead.

2: Thermal insulation can also be used together with fi re insulation or sound insulation.

When the minimum insulation thickness has been found for protecting against sound or fi re, the thermal transmission (U-value) of this material can be calculated from the λ-value. If a higher insulation level is requested the construction can be im-proved by adding an extra layer of a lower density product.

In all cases of insulating towards cold temperatures the wool must always be covered by a vapour tight surface. This surface can be aluminium foil or another kind of vapour barrier. The gaps should be tightly sealed with alu tape.

When adding additional insulation to a fi re construc-tion it should be documented and approved by the local surveyor.

Floor connectionWhen making a surface towards the exterior it is necessary to end the insulation 50 mm above the fl oor. This to make sure that condensate from the bulkhead can be drained away.

In front of the gab, a piece of fl at iron can be fi t to guide the condensate to a drain.

Lambda value/ thermal conductivity () The lambda() value, also referred to as thermal conductivity, is a value indicating how well a mate-rial conducts heat. It indicates the quantity of heat (W), which is conducted through 1 m2 wall, in a thickness of 1 m, when the difference in tempera-ture between the opposite surfaces of this wall equals 1 K (or 1°C). In practice is a numerical value expressed in terms of W/(mK). The lower the value, the better the insulation property of the material.

Examples at 10°CSteel: = 50 W/mKConcrete: = 1.6 W/mKGlass: = 1.1 W/mKWood: = 0.12 W/mKRockwool: = 0.033W/mK

U valueThe transport of thermal energy through a structure is expressed by a coeffi cient, U (Thermal transmit-tance coeffi cient). It represents the fl ow of heat (in W) through 1 m2 of a structure, when the difference between the two surrounding temperatures is 1 K (or 1°C). The thermal transmittance coeffi cient is expressed in W/(m2K). The lower the coeffi cient, the better the structure insulates.

R valueThermal resistance, R, is a measure used in a construction. The R value is the reciprocal value U-value. Increasing the thickness of an insulating layer increases the R value.

Surfaces

Plain Rockwool:This is the basic Rockwool product which is approved and suitable for almost any purpose. The products are based on stone wool which can withstand temperatures above 1,000°C without melting.

Wired Mat with wire mesh:Some of our fi re rated constructions are based on Wired Mat and the wire mesh can form an additional safety to secure the product. Within technical insulation a Wired Mat if often used for high temperatures applications or if you need to bend the insulation around e.g. a pipe.

Wired Mat with reinforced aluminium foil and wire mesh:This surface has the same properties as the Wired Mat but has further more the property of securing a dust free surface.

Reinforced aluminium foil:The reinforced aluminium surface will be the best solution if you need a vapour barrier. The product will secure that no vapour will enter the product and result in corrosion of steel and damaged wool.

Glass cloth:This surface has three major properties: impact resistant, dust free surface and a nicer outlook. This surface will in many cases save the use of an extra metal cladding as the woven cloth is strong enough to resist most impact from the surroundings.

Black glass tissue:The thin black tissue is often used in ventilation shafts or behind a perforated plate as it secures a dust free surface and a nice outlook.

White glass tissue:The thin white surface will secure a dust free surface. The white/transparent look will give a bright surface.

There are many reasons for choosing insulation products with facings. In most cases it is done to obtain a vapour barrier, which prevents formation of condensation on the cold side of a construction. If vapour is the reason for choosing a new surface Rockwool markets different products with reinforced aluminium foil. In other cases it is necessary to have a better look than the pure wool; Rockwool markets different surfaces such as glass tissue and glass cloth. If the need is to secure the product then a surface with wire mesh might be to prefer.

Aquaduct - Thermal Insulation Solutions for Sub-sea Pipelines

Advantages• Resistant to high temperatures• Resilient; good recovery following deformation• Unaffected by welding of fi eld joints• Free from HFCs and other blowing gases• Reliable performance; thermal conductivity cannot

degrade due to loss of entrapped gas• Easy to handle and install• Rockwool Insulation is recyclable and its life cycle

analysis proves that it contributes actively to im-prove the environment.

Due to the fl exibility of the product range of Aquad-uct Solutions we have the capability to offer specifi c solutions to meet specifi c demands, regardless of the complexity of Pipe Bundle confi gurations. These are some examples of the solutions that we have previ-ously offered.

Rockwool insulation products can be tailor made for individual projects and purposes. The most typical products are described below.

Aquaduct CL Aquaduct CL are special patented Rockwool products where the vertical direction of the fi bres provides an excellent compression resistance at low thicknesses (down to 10 mm thickness). The fi bres are bonded to a reinforced aluminium foil outer facing and the product can be supplied with very low tolerances. In most cases Aquaduct CL will be the optimal choice for Pipe in Pipe solutions.

Aquaduct Sections Aquaduct Sections are rigid pre-formed circular units of Rockwool insulation supplied with or without an outer covering. Aquaduct is available in almost any combination of diameter, thickness and length and can be adapted to individual needs and specifi ca-tions. Aquaduct Sections are the optimal choice for bigger sizes of pipe.

Rockwool’s unique product properties are also available for thermal insulation of Sub Sea Pipelines.

Health and Safety - Green Passport

Scientifi c research of man-made mineral fi bres goes back to 1930; to the beginning of the production of these fi bres, which has expanded enormously in a wide range of insulation applications since. The growth in the use of mineral fi bres - also known as Man-Made Vitreous Fibres (MMVFs) - has meant that scientists have needed to describe the effects on public health. Independent institutes worldwide have, consequently, been carrying out extensive animal and epidemiological studies of mineral (glass, rock and slag) wool workers for more than seventy years.

Rockwool Marine & Offshore is part of the Rockwool Group and one of Rockwool’s largest R&D projects ever resulted in the high-alumina low-silica wool generation. This is a quality wool with higher bio-solubility as a result of its chemical composition (see box) and thus a wool with an increased safety margin in comparison with traditional mineral wool. Roxul®1000 fi bers are world wide exonerated from any classifi cation. The product quality of this wool is, of course, consistently high, retaining all technical features.

Green PassportAll Rockwool Marine & Offshore stone wool insulation materials for the marine and offshore market, pro-duced at any of the European Rockwool production plants, will NOT be classifi ed as hazardous materials in relation to the mentioned IMO resolution guideline A.962(23). Therefore Rockwool insulation should not be mentioned in any “Green passport” listings.
