Marine & Offshore Insulation - an overview

Marine & Offshore Insulation - an overview Bridge At the bridge it is important to secure a high level of fire protection and sound insulation. See page 15-40 for A-constructions See page 63-66 for floating floor See page 73-76 for sound 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 floating floor See page 73-76 for sound insulation

Corridors Corridors are part of the emergency escape routes on a vessel. The numbers of horizontal fire zones passed by the corridor determine the fire insulation class. See page 15-40 for A-constructions

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. See page 15-40 for A-constructions See page 73-76 for sound insulation See page 77-80 for thermal 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

Marine & Offshore Insulation - an overview

Offshore On offshore applications you have more or less the same conditions as on a ship. Furthermore you have the risk of hydrocarbon fire and need to protect people and material from an HC fire. 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 fire zones passed by the stairway determine the fire insulation class. See page 15-40 for A-constructions

Galley

Control room Engine room The 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 15-40 for A-constructions See page 67-72 for technical insulation See page 73-76 for sound insulation See page 93 for surfaces

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 reasonable sound level. See page 15-40 for A-constructions See page 73-76 for sound insulation See page 93 for surfaces

In the galley you always have a risk of fire, as you have a mixture of heat and flammable materials. In this case it is also necessary to be aware of the facings as you have oil vapour in the air. See page 15-40 for A-constructions See page 67-72 for technical insulation See page 93 for surfaces

Insulation in General

Insulation in General PREPARATION

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-marine. com. In the following you will find a general description of the way the insulation work can be done:

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 constructions the position of pins must follow the official drawings.

CUTTING

6

Fig. 2. Painting of the plate To avoid corrosion the plate can afterwards be painted with anti corrosion paint.

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

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 fitting the wool. 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.

Insulation in General

INSTALLATION

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 Rockwool insulation. The insulation should fit exactly to the profile structure. Afterwards insulate around the stiffener with the required thickness of Rockwool insulation.

Alternative 1, fig. 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, 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 2, fig. 5A. Insulation of stiffeners Insulate with Rockwool insulation around the stiffener. Fill out the space behind the stiffener with Rockwool insulation, the insulation should fit exactly to the profile structure.

Fig. 6 Fixing the insulation Fix washers on the pins in order to secure fixing of the insulation.

Insulation in General

SECURING THE PRODUCT

Securing the product When installing the insulation all pieces must be fit firmly with minimum 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.

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.

PINS

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

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.

8

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

Insulation in General

VAPOUR BARRIER In rooms where vapour will enter the insulation as a reason of temperature/ 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 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.

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.

STORAGE AND STACKING 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 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, containers and other cargo holds in order to avoid exposure to weather elements and/or condensation etc.

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 flat 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.

Storage of Rockwool insulation The products must at all times be stored dry indoor in closed warehouse facilities.

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.

Calculation of Materials

Calculation of Materials

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

1

2 Based on a plate of X m2. The amount of Batts/Slabs for stiffeners can as guidance be calculated as X times 0.7

Based on a total amount of insulation for plate + stiffeners: The plate equals 60%. The stiffeners equals 40%

Example: 100 m2 of plate needs to be insulated. Calculation of material for stiffener: 100 m2 x 0.7 = 70 m2

PINS AND WASHERS

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/m2 = 1200 pins 100 m2 insulation of stiffeners requires 100 m2 x 10 pins/m2 = 1000 pins

TAPE

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 insulated; also taking the insulation of stiffeners into consideration. Estimated need of pins and washers: 100 m2 x 18 pins/m2 = 1800 pins

WASTE

1

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

As guidance the following amount of waste has to be included: Insulation area < 100 m2 10 % waste Insulation area > 100 m2 5% waste

Example: Tape for 100 m2 of insulation; 100 m2 x 4 m/m2 = 400 metres IN GENERAL THE CUSTOMER IS ALWAYS RESPONSIBLE FOR CALCULATIONS

Choosing the Right Product

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

Rockwool Marine & Offshore has a large number of certificates for the different products and applications from classification companies based on fire tests made at IMO approved fire institutes.

• 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 products have good fire properties, but when using the products on ships or offshore rigs it is necessary to choose the right product fulfi lling the needed fire rating. Furthermore it can be relevant to evaluate the different solutions with regard to the working and installation 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

When choosing a product it is necessary to choose a product that is approved by the classification company 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 fixed products, others prefer to work with constructions 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 certificates When using Rockwool insulation onboard a vessel carrying an EEA flag make sure that the product has the MED approval symbol (wheelmark).

0575/year

It is important to make sure that the products and constructions have the right approval needed in the specific project, e.g. construction approval, noncombustible 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. 11

Requirements for Fire Insulation

Regulations for Fire Insulation According to SOLAS The requirements for materials and constructions to meet specified standards of safety are normally prescribed by international 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 products, as a minimum, meet the statutory requirements. • The MED directive (EC Council Directive 96/98/ EC - Marine Equipment Directive) has replaced the previous approvals 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 stating the permission to use specific materials 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 classification societies, materials and constructions must be proven to comply with the national and international requirements. Tests have to been done at internationally recognised test laboratories.

§ 12

• 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 installations. These classifications are required to prove combustibility 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 material’s fire resistance is done according to FTP code for non-combustibility and where a facing is applied for low flame spread. The most commonly 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 fire technical properties. Construction Test Methods Testing of a construction’s 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/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 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.”

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.

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

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

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

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

Easy handling The construction is based on Batts, where the small size and fixed structure of the products give an easy handling in respect to cutting and installation.

Stiffeners

Stiffeners

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.

450 mm

450 mm

Solas requires that the stiffeners must be insulated*. One way is to insulate without filling the space behind the stiffeners.

Bulkhead and Deck Connections

Bulkhead 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).

A60 Bulkhead or Deck

Connections between A-60 and A-0 constructions 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 A0 bridge. Min. 450

Additional insulation Steel Bulkhead/Deck

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 A0 Min. ignition inside the 450 Steel Bulkhead/Deck connecting room.

* Rockwool recommends 900 mm to secure that the heat always go min. 450 mm under the insulation before reaching an unexposed surface.

Draught Stoppers

Draught Stoppers

Draught stoppers are used above ceilings to avoid the spread of smoke and flames in case of fire. Normally the classification companies request a B-0 fire insulation above the ceiling. This can be made from Rockwool 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 fixed with ø3 mm pins and secured with ø38 mm washers. Installation Step 1: First the pins are welded vertically to the underside of the deck in alignment with the required position of the Draught Stopper. Step 2: The pins are then bent 90° in a staggered pattern as shown. Step 3: The Rockwool 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, 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 Rockwool must be stitched/taped back together using steel wire/alu tape. • This solution can be used for any type of penetration including multiple penetrations.

Penetrations

Penetrations of fire protection When pipes, ducts or other go through a bulkhead or deck it is called a penetration. There are special rules regarding insulation when the decks or bulkheads with fire class are penetrated. The pipe going through a fire classed structure must be made of steel and must have a length of minimum 900 mm. IMO suggests to use min. 450 mm on each side of the construction.

Floating Floor Constructions

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 200 This solution consists of two layers Rockwool Marine Slab 200, 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 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 floor screed will have to be used as first layer; a fire retardant PE compound, cement based fi ller 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.

64

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 requirements for mechanical strength and floor finish. As flooring 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.

Floating Floor Constructions Rockwool Marine & Offshore is preferred supplier for many marine flooring companies. These companies integrate the Rockwool products in their more sophisticated solutions.

Note: Deviations from the certified A-60 floating floor construction in any form, could require new approval by the Class Society or National Marine Authority.

2) Marine Slab 140 This 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 fire 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 reduction. Please note that the compression strength of this solution is lower than the Marine Slab 200 solution. The first 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 finish.

Sealing of edges to prevent structural noise

Enclosing: For the perimeter of the construction it is recommended to finish the insulation with a rigid Rockwool product i.e. Rockwool Marine Slab 140 or 200 placed edgeways and sealed with a flexible sealant. Many of the flooring companies are using Rockwool Marine Slabs in densities of 140 - 200 kg/m3, in combination with more complex top layers. The max load for the complete flooring construction will depend entirely on the top layer. The load capacity of the specific construction is to be calculated and tested by the flooring company. Rockwool Marine & Offshore is preferred supplier for many dedicated marine flooring companies. These companies then create more sophisticated solutions for superb noise reduction in both high and low frequencies. 65

Technical insulation

Technical Insulation Technical Insulation in General To guarantee a correct process cycle, the condition of the media within the pipes must remain within the set limitations (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 efficiency of the process cycle throughout the design service life without losses as a result of faults.

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 influences such as weather or mechanical loads. Spacers are also essential with insulation material such as wired mats, which do not offer sufficient resistance 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 structures are fitted to take on the loads of the insulation and the cladding. In general, support structures and spacers form thermal bridges. HVAC Insulation - Pipes For the HVAC (Heat Ventilation Air Condition) applications 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. 68

The benefits of correct thermal insulation for piping include: • Reduction of heat losses • Cost savings • Reduction of CO2 emissions • Frost protection • Process control: ensuring the stability of the process temperature

• Noise reduction • Condensation prevention • (Personal) Protection against high temperatures Airducts Today, many requirements are made on air ducts. Most important is that the comfort on board the vessels or platform living quarters is considered and that no compromises are made to the demands on fire safety. In connection with ventilation of cabins and other rooms it must furthermore be ensured that no condensation is formed and that the required temperature is maintained all the time. This is obtained by using one of the Rockwool Marine & Offshore products in the correct thickness. Thickness calculation program can be found on our webpage.

Technical insulation

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 fit 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 negative influence on the insulation, is greatly reduced.

Banding • Rockwool recommends that the Pipe Section is secured 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).

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 fit of the insulation. • The outer layer(s) of the section should be applied with staggered joints, both laterally and longitudinally.

69

Technical insulation

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 fit 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 • Marine Lamella Mat 32 consists of stone wool lamellas placed edgewise, the majority of the fibres being 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 fibres 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 finish on the Marine Lamella Mats, should be taped at all joints. • The mats are secured with steel banding.

70

Technical insulation

Insulation with Marine Wired Mat • 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 flexibility and high temperature resistance, Marine Wired Mats can easily be cut and fixed onto the piping.

These wired mats are ideal for application in situations where the use of Pipe Sections is difficult or impossible: • Temperatures above 300°C • Pipe diameters ≥ ø350 mm • Piping with a high number of shaped pieces such as elbows or T-joints.

• Marine Wired Mats have a relatively low resistance to pressure and from a practical point of view should only be installed in combination with spacers. Due to the thermal bridges of this combination 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 consistently tight fit of the insulation. • The outer layer(s) of mat should be applied with longitudinally staggered joints and where applicable, with staggered joints laterally. 71

Technical insulation

Insulation with Marine Slabs/Batts • 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 temperatures 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 retaining 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 flat or profi led external cladding to protect them from the weather and mechanical damage.

Cladding Suitable cladding should be applied to protect the insulation from weather influences, mechanical loads and (potentially corrosive) pollution. Selecting the appropriate 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, fire resistance and low surface temperature (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 fire risk. 72

• The surface temperature of the cladding is influenced 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 material (Lead layer, polyethyten foil) is installed on the insulation or inside the cladding. To reduce the risk of fire, limit the surface temperatures of the cladding to the maximum operating temperature of the noise absorbent material.

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 sufficient 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.

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 find the sound absorption coefficient, αw for the most common Rockwool Marine & Offshore products.

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 measurements 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 standardized 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 flanking sound transmission. Rw is the laboratory value for the weighted sound reduction without flanking transmission.

Thermal Insulation

Thermal Insulation

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 properties is by using the following nomenclature: • Coefficient 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. Specification of the λ-value should therefore be referred to as “mean” temperature and, if possible, to a standardised method for measurement and calculation.

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 fire insulation or sound insulation. When the minimum insulation thickness has been found for protecting against sound or fire, 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 improved by adding an extra layer of a lower density product.

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

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 fire construction it should be documented and approved by the local surveyor. 78

In front of the gab, a piece of flat iron can be fit to guide the condensate to a drain.

All Rockwool Marine & Offshore products fulfil the IMO rules of “noncombustibility” and “low flame spread”. Besides this the products have excellent water repellent properties which are also important as thermal insulation is often placed directly up against the outer construction with changing temperatures.

Thermal Calculations

Thermal Calculations

Lambda value/ thermal conductivity () The lambda() value, also referred to as thermal conductivity, is a value indicating how well a material 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 temperature 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°C Steel:  = 50 W/mK Concrete:  = 1.6 W/mK Glass:  = 1.1 W/mK Wood:  = 0.12 W/mK Rockwool:  = 0.033W/mK

 = W/mK

Most materials will increase in  at rising temperatures.

U value U = W/m2K

U=

 Thickness

The transport of thermal energy through a structure is expressed by a coefficient, U (Thermal transmittance coefficient). It represents the flow 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 coefficient is expressed in W/(m2K). The lower the coefficient, the better the structure insulates.

R value 1 Thickness(m) R = U or R =  ( W/mK)

Examples The steel plate is not taken into consideration due to the low added value. Marine Batts 45, 50 mm (10 = 0.034 W/mK) R = 0.05/0.034 = 1.47[m2K/W] U = 0.68[W/m2K]

80

Thermal 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.

Marine Firebatts 100, 60 mm (10 = 0.035 W/mK) R = 0.06/0.035 = 1.714[m2K/W] U = 0.57[W/m2K] Marine Firebatts 100, 60 mm + Marine Batts 45, 50 mm (10 = 0.035 W/mK 10 = 0.034 W/mK ) R = (0.06/0.035) + (0.05/0.034) = 3.18[m2K/W] U = 0.31[W/m2K]

Marine Batts 45, 100 mm (10 = 0.034 W/mK)

Marine Firebatts 100, 60mm + Marine Batts 45, 100mm (10 = 0.035 W/mK 10 = 0.034 W/mK )

R = 0.1/0.034 = 2.94[m2K/W]

R = (0.06/0.035) + (0.1/0.034) = 4.65[m2K/W] U = 0.21[W/m2K]

U= 0.34[W/m2K]

Surfaces

Surfaces

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.

ROCKWOOL

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

Wired Mat with wire mesh: Some of our fire 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 REINFORCED ALU

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 ALU

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 - 200 g/m2 (GW200) + 400 g/m2 (GW400)

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. GLASS TISSUE BLACK

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.

GLASS TISSUE NATURAL/WHITE

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

Health and safety - Green Passport

Health and Safety - Green Passport

Scientific research of man-made mineral fibres goes back to 1930; to the beginning of the production of these fibres, which has expanded enormously in a wide range of insulation applications since. The growth in the use of mineral fibres - 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 biosolubility 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 fibers are world wide exonerated from any classification. The product quality of this wool is, of course, consistently high, retaining all technical features. Green Passport All Rockwool Marine & Offshore stone wool insulation materials for the marine and offshore market, produced at any of the European Rockwool production plants, will NOT be classified 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.
