Scope
A global oil and gas operator has utilised ICR’s composite repair technology, Technowrap™, to complete multiple repairs on its Utilities and Quarters (UQ) platform in the North Sea.
During a routine assessment, the operator identified several areas of corrosion on the accommodation roof and approached ICR for a quick, cost-effective, and long-term solution with a 20-year design life. The repair needed to reinforce the remaining carbon steel, which averaged 1mm in thickness, with a design load of 0.005/mm².
The project scope included working with the onboard inspection and FM team to ensure that the Technowrap™ application ran smoothly and was within the design requirements for ISO 24817. Following the inspection, the FM team were instructed to cold bond carbon steel plates to which the Technowrap™ SRS/DRS was then applied to bring the wall thickness to the operational requirements.
Solution
ICR collaborated with Stork, a global provider of integrated operations, maintenance, modification and asset integrity solutions, to deliver a suitable adhesion level through surface preparation as well as the use of various compression aids to allow for an even surface.
When engineering the design for this project, our experts considered the client’s specific requirements while ensuring compliance with industry standards. After design calculations were complete, our team determined an optimal solution compromising Technowrap™ SRS (Structural Rehabilitation System) – a carbon fibre cloth – and DRS (Deck Rehabilitation System), a rubber toughened epoxy resin.
Three layers of this solution, resulting in a repair thickness of 2.70mm, would restore the integrity of the roof areas while ensuring a 20-year design life.
Result
Requiring just one technician and one supervisor to complete the multiple repairs within the desired timeframe, this proved to be a very cost-effective and efficient project for our client.
Pleased with the results, the operator has requested our continued support for additional composite repairs in other areas of the asset.
