Technowrap™ composite repairs

barcol reading of technowrap™ composite repair

Defined life repair technology for damaged pipework, pipelines and structural components.

Technowrap™ is a versatile long-term alternative to steel replacement that offers practical and cost-effective rehabilitation and minimal disruption to operations. Applied to live targeted areas, with no requirement for shutdown, it supports safe operations while optimising production uptime whilst delivering tangible cost savings and environmental benefits.


With our extensive experience spanning over 30 years, we are a global market leader in the field of composite repair technology, reshaping how we preserve and maintain critical assets and infrastructure. Our bespoke engineered repair systems use either glass or carbon fibre stitched cloths, combined with two-part epoxy resins that are suitable for a range of design or environmental requirements.

Technowrap™ can offer high end design features with a temperature range of -75ºC to 220ºC (-103ºF to 428ºF), a capability to address internal and external corrosion, though wall defects with pressure test data up to 1400 BarG (20305 PSI). For structural applications, ICR have developed our own in-house practices which refer to the principles from ISO 24817 / ASME PPC2, DNV and ABS which we can then incorporate hand calculations or FEA and are supported by in house or third-party testing.

What can we repair?

Pressure System Repairs 

  • Critical and non-critical pipework, all components, including bends, tees, and flange and clamp overwraps.
  • Pipelines
  • Vessel repairs
  • Composite live leak sealing
  • Splashzone and subsea repairs (including all wet environments i.e. high humidity)
  • Caisson and risers, leak sealing and corrosion protection


Structural Repairs 

  • Structural strengthening of caissons and risers
  • Strengthening of decks, roofs and floors and drip pans
  • Strengthening of tanks and vessels (shells, supports & nozzle attachments)
  • Blast Walls, panels, and accommodation modules.
  • I-beams, CHS members
Composite repair on pipe

Pipework Repairs

Repairs engineered to ISO 24817 or ASME PCC-2 401 considering hoop and axial stresses and through wall defects (where applicable) using bespoke composite materials developed for the repair scenario.
Deck before composite repair

Deck Repairs

Utilising a core-shell toughened resin, Technowrap™ DRS combines the properties of carbon fibre and the epoxy matrix to provide strength, adhesion and impact resistance, all critical to the repair of decks.

Caisson Repairs

Caisson repairs follow a similar design premise to pipework however they must also consider external loadings, including bending moment induced by wind and wave loading; axial load; often from the weight of the caisson in event of full separation.
Pipeline outside with composite repair

Pipeline Repairs

Using a very similar design premise to pipework, the ISO 24817 and ASME PCC-2 401 standards are used to provide engineered repairs to pipelines where wither hoop and axial stresses are present
Tank roof being repaired

Tank & Vessel Repairs

Engineered for internal or external repairs to pressure vessel shells and components including dome ends and nozzles as well as storage tank shells, roofs, and bases.
Structural beam prepared for composite repair

Stuctural Component Repairs

Using composite materials, typically carbon fibre due to its high tensile modulus to reinstate structural components to their design loading capacity.
Splashzone repairs

Splashzone & Subsea Repairs

Splashzone resin can be applied live in wet environments. The hydrophobic epoxy resin displaces moisture from the bond line, ensuring the appropriate, tested level of adhesion is achieved.

Live Leak Sealing

Using our range of leak sealing methods, ICR can provide repairs for low pressure leaks without the need to shutdown or isolate.

Track Record

Technowrap has been utilised on tens of thousands of installations worldwide, giving operators added reassurance through our experience and in-service application history. Our in-house integrated service provides engineering, materials, training, and installation, which has enabled us to become the industry specialist, having dealt with some of the most challenging projects in the industry both on and offshore.

We have proudly led the industry in the development and adoption of composite repair technology and are key member of both ASME and ISO committees. Technowrap™ is internationally recognised and all engineering is bespoke and completed in-house, in accordance with the latest issues of ISO 24817 and ASME PCC-2. Our engineering designs are carried out to current code requirements and are validated by a range of material property and design scenario testing which has been independent by third parties (Lloyds Register, ABS Design & Manufacturing, DNV Type Examination) and certified as fully compliant.


  • Design Flexibility: Can be designed to match the specific mechanical properties required for a repair, allowing for customisation. They are full engineered and come with traceability and documentation to support design basis.
  • Defined life: In accordance with ISO 24817, the design lifetime is between two and 20 years, allowing operators to extend the life of their assets or get through to the next available shutdown.
  • Reduced Downtime: The repair is targeted and can be applied live with no shutdown and no hot work and an often be carried out without the need for extensive dismantling.
  • Strength and Weight: Can be tailored to provide high strength while remaining lightweight, making them suitable for applications where minimizing weight is crucial.
  • Corrosion & UV Resistance: No significant maintenance during the defined life (RBI is recommended). They are corrosion resistant and UV tolerant meaning the composite material will not degrade due to environmental factors.
  • Reduced cost, time and POB: Can be applied live, limited impact on production and are more cost effective compared with replacement.
  • Environmental benefits: 66% reduction in carbon emissions comparative to traditional replacement.
  • INSONO™ Inspection: Interlaminar, bond line and substrate can be inspected using INSONO™
