Advanced Insulation manufactures a wide range of products for the Subsea industry.

Subsea Systems and Products

Advanced Insulation’s ContraTherm®

range of phenolic and silicone based

resin systems have been engineered

for high temperature environments.

ContraTherm® C55 and C25 meet the

most technically demanding subsea

insulation challenges, developed

to meet the need for resilient

insulation capable of tolerating the

temperature and pressure extremes

required for high temperature

developments.

For Subsea Buoyancy, Advanced

Insulation offer a range of

installation buoys and engineered

buoyancy for flowlines,

manufactured from lightweight

syntactic foams which can perform

in depths in excess of 3000MSW.

Advanced Insulation also produce subsea, umbilicals, risers and flowlines (SURF) protection for bend limiting,

fatigue prevention, impact and abrasion prevention as well as a range of piggyback saddles and clamps, banding

and banding tools.

6

Advanced Insulation specialises in the manufacture and supply of unique syntactic foam

insulation systems designed for upstream oil and gas infrastructures. Focusing on phenolic

and silicone based resin systems for high temperature environments, Advanced Insulation

offers solutions to the most technically demanding subsea insulation challenges.

The effective use of insulation

materials on subsea pipelines and

equipment assists flow assurance

by maintaining flow rates which in

turn optimises productivity and

therefore lowers processing costs.

Insulating subsea equipment

reduces the cooling of reservoir

fluids and maintains them above

temperatures at which waxes

and hydrates may form, thereby

minimising the risk of diminished

flow rates and blockages.

Insulation may be applied to subsea

equipment including but not limited

to pipelines, Xmas trees, manifolds,

jumper spools, pipe line end

terminations and flange connections.

As oil and gas production

extracts fluids of ever increasing

temperatures from deeper waters

and at longer tie-back distances

from the host structure, the benefit

of insulating subsea equipment

becomes increasingly apparent.

With fluid temperatures approaching

180ºC (356ºF) and at water

depths approaching 3,000 msw

(10,000 fsw) the need for a high

temperature, high pressure

insulation material capable of

withstanding such environmental

extremes becomes a consideration

of paramount importance.

Advanced Insulation has developed its ContraTherm® solutions specifically to meet the

need for resilient insulation materials capable of tolerating the temperature and pressure

extremes required for high temperature developments. The ContraTherm® systems are

engineered to withstand the particular service requirements demanded by offshore oil

and gas production and come into their own where high temperature, high pressure field

developments are concerned.

ContraTherm® Subsea Systems

Phenolic resins are widely used in high

temperature applications and are the

acknowledged choice for elevated service

temperatures. Advanced Insulation

recommends the C55 Series for service on

less dynamic applications such as Xmas

trees, manifolds, supported jumpers and

pipeline end terminations.

C55 Syntactic Phenolics

Silicone resins offer a highly flexible,

high temperature insulation system

that is fast becoming the recognised

solution for dynamic application service.

Advanced Insulation recommends

the C25 Series for service on dynamic

applications such as production jumpers,

tie in spools and steel risers.

C25 Syntactic Silicones

The use of ContraTherm® on subsea pipelines and equipment assists flow assurance by maintaining flow rates, which will in turn optimise productivity and lower processing costs.

ContraTherm® can be applied to subsea equipment such as Xmas trees, manifolds, jumper spools, pipeline end terminations and flange connections.

ContraTherm® C55 is a multi-layer syntactic phenolic composite system with properties

that can be tailored to meet specific project requirements. Syntactic foams have been

used in the offshore industry for more than 30 years and have become one of the

key materials used in ever more demanding subsea applications. The low thermal

conductivity and robust mechanical structure of ContraTherm® C55 are ideally suited for

subsea thermal insulation applications.

The individual elements of the

multi-layer system provide their own

particular benefit and combine to

provide a value for money solution.

The D2004 phenolic composite top

coat provides an extremely robust,

impact resistant, hard wearing outer

skin with a surface finish tailored

to suit project requirements. The

composite consists of multiple

glass fibre layers impregnated with

phenolic resin to form a tough outer

skin of nominal 4mm thickness. This

composite also provides a barrier

to water ingress limiting water

absorption in the insulation foam.

ContraTherm® insulation foam

consists of an optimised fill of

glass microspheres dispersed and

supported within a phenolic resin

matrix which provides the necessary

integrity and strength. The thickness

of the core material is determined

by the insulation performance

requirements of the specific project.

There are several ContraTherm®

material grades individually

developed for differing water depth

requirements.

ContraTherm® Tie Coat provides a

tacky interlayer which bonds the

syntactic foam core material and

gives good bond integrity to the

substrate. Tie Coat may be applied

directly to shot blasted steel coated

with the standard high performance

anti-corrosion coatings widely

used by the subsea equipment

manufacturers.

C55 ambient curing properties

make the system ideal for direct

application to equipment on

construction or manufacturing

sites globally. The hand applied

application methodology combined

with the minimum requirement for

complex application equipment,

and the absence of mould

tooling, ensures C55 is a very

flexible material to apply from a

scheduling perspective; a benefit

where complex equipment build

programmes are involved.

The final layer of the GRP top skin

is a resin flow coat to finish the

laminating process. The standard

colour for the flow coat is yellow

however other standard RAL colours

may be used to suit the client’s

requirements.

The yellow flow coat ensures the

insulation is visible to ROVs on

subsea operations.

The C55 Subsea System is equally

comfortable in ‘hot/wet’ or ‘hot/

dry’ conditions and is therefore ideal

for use in a retrofitted insulation

system for flange protection covers

or doghouses.

Advanced Insulation reports both

new and aged thermal conductivities

for the bare C55 foam. Advanced

Insulation recommends that the

aged values are used in all thermal

calculations providing a more

conservative coating thickness.

ContraTherm®

C55 Subsea Insulation System

The C55 insulation foam thickness

will be determined by calculation

from the thermal conductivity

or specific heat capacity to meet

the required overall heat transfer

coefficient or cool down criteria. C55

is applied in layers until the required

thickness is achieved. There is no

practical limitation to the thickness

of insulation that may be applied.

ContraTherm® C55 will perform as

an integrated system fully bonded at

all interfaces under the anticipated

exposure conditions.

Glass MicrospheresThe excellent thermal performance

and high hydrostatic pressure

capability of C55 insulation foam is

provided by the presence of specially

developed glass microspheres

supported in the phenolic resin.

The microspheres are microscopic

closed cells of borosilicate

glass which exhibit very stable

insulation properties over long

term environmental exposure. The

phenolic binder does not absorb

water and any voids between the

microspheres and the resin represent

an almost insignificant volume into

which water can ingress. Advanced

Insulation has tested for and

established the maximum water

absorption of the C55 insulation foam

which occurs when the bare foam is

exposed to highly pressurised water.

ContraTherm® C55 ambient curing makes it ideal for direct application to equipment

on construction or manufacturing sites globally.

The Tie Coat may be applied directly to shot blasted steel coated with the standard high performance anti-corrosion coatings widely used by subsea equipment manufacturers. There are several C55 material grades individually developed for different water depth requirements.

ContraTherm® C55 is supplied either as a wet coating applied directly to the corrosion

coated substrate in the field or as a pre-moulded engineered component. A combination

of both methodologies may provide the best solution in certain applications.

ContraTherm®

C55 Direct Application Method

The process of direct application

involves mobilising materials,

equipment and personnel to

construction sites worldwide and

applying the ContraTherm® C55

system directly to the equipment

substrate. The ContraTherm®

C55 Subsea System’s cold curing

properties make it an ideal material

for direct application at any stage in

the build programme of the subsea

equipment, including finished

assembled packages such as Xmas

trees and manifolds. This allows the

EPC contractor to fit the application

of thermal insulation into the

overall delivery programme with

a great degree of flexibility. This

application methodology, not

requiring the construction of any

mould tooling or formers, makes it

possible to apply ContraTherm® in

areas which would normally prove

difficult to access.

In its wet state, the core material

has a bread dough consistency and

is designed to be easily applied

to equipment and pipe work in

layers of up to 20mm thickness

at a time without sagging. The

material does not experience

shrinkage during curing enabling

accurate thickness control. The

application process guarantees

joints will become homogenous

ensuring there are no weak

points in the system. The process

is relatively simple and makes

any modification or adjustments

to the insulation thickness and

coverage during application

quick and simple. The composite

outer skin will be applied to the

ContraTherm® core once the curing

process is sufficiently advanced.

The individual glass fibre layers are

wrapped onto the core material

and impregnated with resin

between each individual layer.

11

The ContraTherm® C55 System does

not require the fabrication of mould

tooling nor does it require complex

pumping equipment.

The ContraTherm® C55 System

utilises simple mixing and application

equipment which is readily available

and does not require extensive

maintenance or spares in the field.

The relative simplicity of the

application process makes the

ContraTherm® C55 System an ideal

material for application using local

labour with suitable training and

under the supervision of Advanced

Insulation technicians.

The ContraTherm® C55 System is

supplied in pre-measured and pre-

packaged kits to ensure

correct usage.

Where the ContraTherm® C55 System

is directly applied, the insulation

foam may be shaped to suit detailed

interface requirements prior to

curing. The post cured composition

and texture of C55 insulation foam

ContraTherm® is ideally suited

for machining using standard

woodworking type equipment.

This means that the removal of the

ContraTherm® C55 System is straight-

forward should it be required.

The ContraTherm® C55 Subsea System’s ambient curing properties make it an ideal material for direct application at any stage in the build programme of subsea equipment, including finished assembled packages such as Xmas trees and manifolds.

12

ContraTherm® C55 can be moulded into pre-designed shapes to suit the equipment to be

insulated. Such mouldings may be required to reduce application times and/or to provide

for articulation or removable solutions where later access may be required.

Pre-moulded components require

some pre-engineering but their use

can increase operational flexibility

by reducing the on-site insulation

schedule and may shorten the

overall equipment lead-time and

critical path.

C55 components are produced

by compression moulding. The

material properties allow intricate

single piece mouldings to be

manufactured. This is advantageous

as large or complex mouldings need

not be manufactured in smaller

subassemblies and subsequently

bonded together risking potential

weak spots at the joint interfaces.

Pre-moulded components come in

a range of shapes and sizes from

relatively simple moulded panels,

blocks or half-shell C-sections, up

to the most complex connector

cover arrangements such as ROV

installed ‘doghouse’ mouldings. Each

design is engineered to match the

dimensions of the component to be

insulated and produced in highly

accurate compression moulds. The

shapes are subsequently fastened

to the structure by the most suitable

means, from simple strap banding

arrangements to complex ROV

operated closure systems, and

sealed as appropriate to minimise

water flow and retain insulation

performance. Whilst Advanced

Insulation will mould very complex

components individually, the

bonding of subordinate pieces can

be achieved by the use of proven

subsea epoxy adhesives. These

adhesives also allow the bonding

of panels directly to the substrate

when necessary.

A simple pre-moulded solution, such

as a panel for subsequent bonding

to a flow meter or valve body or

a pair of C-section half shells for a

pipe field joint arrangement, would

be delivered to site in a kit form

consisting of the insulation pieces,

the epoxy adhesive and the strap

banding or other form of mechanical

fastening.

The design of even simple

components is engineered to suit

specific demands, from jigsaw

arrangement removable pieces to

application time driven fast field

joint covers for offshore pipe-lay

operations.

ContraTherm®

C55 Pre-moulded Engineered Components

13

More complex components are

delivered in their final assembled

condition in advance of final

installation. This may involve the

fixing into position of painted

steel handling and closure frames

and sealing arrangements to

minimise the flow of water

through the cover. Advanced

Insulation supplies all associated

bespoke steel fixtures, seals and

other accompaniments required

for specific insulation component

designs whether surface or subsea,

diver or ROV installed.

The design of connector covers

is complex and usually individual

to each application. Advanced

Insulation engineers work closely

with clients to develop the most

suitable solution, taking a holistic

approach from manufacturing

capability through to ease of

installation whilst maintaining

a specific focus on the project

requirements.

Pre-moulded components come in a range of shapes and sizes from relatively simple moulded panels, blocks or half-shell C-sections up to the most complex connector cover arrangements such as ROV installed ‘doghouse’ mouldings.

Contratherm® C25 is a specially formulated two part syntactic silicone system tailored

to meet stringent subsea requirements. Syntactic silicone foams have been used in the

offshore industry for 10 years and syntactic foams in general for over 30 years. The low

thermal conductivity and flexible nature of Contratherm® C25 make it an ideal product for

subsea thermal insulation on dynamic structures.

C25 insulation foam consists of an

optimised fill of glass microspheres

dispersed and supported within

a silicone resin matrix which

provides the necessary integrity and

strength. The thickness of material

is determined by the insulation

performance requirements of the

specific project.

C25 is applied by direct casting to

shot blasted steel coated with the

high performance anti-corrosion

coatings widely used by the

subsea equipment manufacturers.

Contratherm® Primer is first applied

to the substrate to provide an

interlayer to the syntactic foam core

material and to give good bond

integrity to the substrate.

C25 products are applied at room

temperature so there is no need to

heat the substrate being insulated.

C25’s ambient curing properties

make the system ideal for direct

application to equipment on

construction or manufacturing

sites globally. The pump in situ

application methodology, combined

with non complex standardised

equipment, ensures that C25 is a

very flexible material to apply from

a scheduling perspective; a benefit

where complex equipment build

programmes are involved.

The application strategy is to use

multiple low capacity pumps to

maximise flexibility, increase ease of

handling and provide redundancy at

the operating site. Multiple pumps

provide the option of filling moulds

in parallel.

C25 is applied by pumping the

material into moulds fitted to the

substrate to provide the required

insulation thickness and profile. The

silicone resin has a greater open

time than other pumped materials

which allows a slower and more

considered pumping strategy. The

rheology of the material requires a

slower pump speed which allows

the operator sufficient time to

manage the pumping process.

C25 is a flexible insulation material

that is capable of absorbing the

stresses applied through structure

movements in service. Stresses are

caused by the movement of the

pipe structures through thermal

expansion at elevated operating

temperatures, pipe deflections and

natural movement. The material

will absorb such stresses without

cracking or buckling.

The standard colour for C25 is

yellow, however, other standard

RAL colours may be used to suit

the client’s purpose. The yellow

colour provides high visibility to the

insulation to ensure it is visible to

ROVs on subsea operations. C25 is

equally comfortable in ‘hot/wet’ or

‘hot/dry’ conditions and is therefore

ideal for use in a retrofitted

insulation system where ease of

subsequent removal is important.

ContraTherm®

C25 Subsea Insulation System

15

The C25 insulation foam thickness

will be determined by calculation

from the thermal conductivity

or specific heat capacity to meet

the required overall heat transfer

coefficient or cool down criteria.

The C25 system is applied by filling

moulds to the required thickness in

a single pour. There is no practical

limitation to the thickness of

insulation that may be applied. The

system will perform as an integrated

system fully bonded at all interfaces

under the anticipated exposure

conditions.

During mould tool design Advanced

Insulation will be able to manipulate

client CAD models to optimise

mould design.

The mould tools are designed to be

robust and reusable yet simple to

aid ease of installation and removal.

Glass Microspheres

The excellent thermal performance

and high hydrostatic pressure

capability of C25 is provided by the

presence of specially developed

glass microspheres supported in

the silicone resin.

The microspheres are microscopic

closed cells of borosilicate

glass which exhibit very stable

insulation properties over long

term environmental exposure. The

silicone binder does not absorb

water and any voids between

the microspheres and the resin

represent an almost insignificant

volume into which water can

ingress. Advanced Insulation has

tested for and established the

maximum water absorption of the

C25 insulation foam which occurs

when the C25 is exposed to highly

pressurised water.

The ContraTherm® C25 Subsea System’s ambient curing properties makes the system ideal for direct application to equipment on construction or manufacturing sites globally.

The primer may be applied directly to shot blasted steel coated with the standard high anti-corrosion coatings widely used by subsea equipment manufacturers.

Once cured ContraTherm® is sufficiently robust to allow transportation without the need for further protection beyond that typically required for the equipment itself.

Micrograph of C25

16

ContraTherm® C25 is supplied as a wet coating applied directly to the primed substrate

in the field. Engineered components can be moulded to provide removable insulation

solutions for certain applications.

The process of direct application

involves mobilising materials,

equipment and personnel to

construction sites worldwide and

applying the ContraTherm® C25

system directly to the equipment

substrate. The ContraTherm® C25

system’s ambient curing properties

make it an ideal material for

direct application at any stage

in the build programme of the

subsea equipment, including

finished assembled packages such

as jumpers and manifolds. This

allows the EPC contractor to fit the

application of thermal insulation into

the overall delivery programme with

a great degree of flexibility.

The application methodology

requires the construction of mould

tooling which is engineered to suit

any areas that are more difficult

to access. This is not an issue with

jumpers and tie-in spools which are

the key service application for C25.

The material does not experience

shrinkage during curing enabling

accurate thickness control. The

application process guarantees joints

become homogenous ensuring there

are no weak points in the system

The C25 product is a two part high

viscosity liquid material applied by

using a plural component pump.

Application is by means of pumping

the mixed material into moulds

constructed around the structure

being insulated. The material is

poured into the cavity between

the substrate and the mould tools

guaranteeing the thickness and

position of the insulation. Tools are

generally reusable to provide a cost

efficient system of application.

C25 Direct Application Method

ContraTherm®

17

The mould tools dictate the

dimension and profile of the

insulation moulding. Each moulding

is profiled to accept the adjacent

moulding to ensure correct bonding.

Contratherm® primers are used at all

interfaces to ensure good bonding

between insulation mouldings

and the substrate. The primers are

pigmented to highlight coverage

during the application process.

The bond strength created by the

primer is greater than the strength

of the bulk material. C25 can be

cast to any thickness subject to any

practical limitation within the subsea

structure’s dimensions.

The ContraTherm® C25 Subsea System’s ambient curing properties make it an ideal material for direct application at any stage in the build programme of subsea equipment, including finished assembled packages such as jumpers and manifolds.

Once cured, ContraTherm® C25 is sufficiently robust to allow transportation without the

need for further protection beyond that typically required for the equipment itself.

C25 is applied in ambient conditions

and does not require the substrate

to be preheated. The material is

ambient curing and does not create

internal stresses or impose stresses

on the substate. This process

ensures long term security of the

insulation system as the risk of future

separation of individual mouldings is

negated.

C25 material is easily removeable

with the correct tools and is easily

repaired using the same application

process. Whilst closed moulds are

normally used, open moulds can

be used, when required by the

application.

18

Material Definition

Extensive laboratory scale testing

is completed to determine material

properties in new and aged

conditions. Such testing enables

material performance to be defined

according to:

Temperature Capability

Hydrostatic Pressure Capability

Thermal Performance

Material Density

Mechanical Performance

Water Absorption Resistance

Full Scale Testing

Service capabilities of the materials

are also determined by laboratory

testing. However, it is essential to

verify the materials performance at

the full scale to demonstrate ‘fitness

for purpose’. Advanced Insulation

have tested their products predicted

service performance through:

Simulated Service Testing

Thermal Cycling Testing

Cool Down Testing

Cathodic Disbondment Testing

Advanced Insulation has successfully

tested its products to major oil

company qualification programmes,

further full scale testing can be

undertaken to meet individual project

requirements.

Chemical Resistance

ContraTherm® shows exceptional

chemical resistance, not only to

seawater, oils and solvents, but also

acids and other aggressive chemicals.

This is advantageous in that

ContraTherm® will not be affected

by accidental exposure to materials

and liquids typically used in the

production and installation phases of

a project.

Mechanical Stability

ContraTherm® provides excellent

mechanical stability. The insulation

properties of ContraTherm® will not

significantly change with time which

is important considering extended

duration field design lives. Water

absorption into the material initially

affects mechanical and thermal

properties, however once the system

reaches equilibrium in service these

properties will remain constant.

ContraTherm® insulation foam is a

closed cell structure which is highly

resistant to water permeation in the

event of any accidental damage or

exposure to water.

ContraTherm®

Material & Technical Properties

ContraTherm® has been developed thanks to continuing investment in research and

development within Advanced Insulation’s own laboratories and through qualification

programmes often involving third party facilities. In developing the materials, a constant

focus was maintained on the critical parameters required of high temperature, high

pressure insulation materials. The material evaluation process can be split into two main

categories, material definition and full scale performance testing.
