Scope
A multinational oil and gas company engaged ICR to deliver multiple composite repairs aboard one of its major LNG carriers. Located in Doha – Qatar, the tanker featured carbon steel ballast water lines that had developed through-wall defects as a result of corrosion.
After assessing the asset condition, including defect dimensions, pipe geometry, operating pressure, temperature and coating condition, ICR engineered Technowrap™ composite repair solutions to restore the structural integrity of the ballast water system with a design life of 10 years.
Once the repair design was approved, we quickly mobilised personnel and materials to the vessel.
Solution
The first repair location, situated on a valve within the ballast line, required full encapsulation using eight layers of our Technowrap™ composite system incorporating our High Ambient (HA) resin.
The second repair location on the main line required an eight-layer patch repair to address a through-wall defect on a 24″ carbon steel section.
Following surface preparation at each defect location, our technicians systematically applied the composite layers according to the engineered design. Final QA/QC checks, including visual inspection and hardness testing, were performed to verify the quality and integrity of each repair before demobilisation.
Results
Despite the need for two different repair types, complete valve encapsulation and a patch repair, ICR’s team successfully engineered, mobilised, and delivered the repairs within the customer’s required timeframe and budget.
A seamless project from start to finish, ICR has since continued to support this client with further composite repairs across its major assets.
