Composite Restores Riser Integrity Offshore

When a corroded riser was found on an oil platform offshore Africa, the owner needed a solution that would minimize production loss. But this was a challenging repair. The damaged riser included a section of pipe that had been welded, creating an uneven surface; so in addition to addressing corrosion, the repair would have to contend with alignment and weld bridges.

Clock Spring had the answer – the Clock Spring composite repair sleeve and reinforcement system.

Clock Spring-trained and certified technicians prepped the line and filled in the corroded areas, then applied Clock Spring repair sleeves to the riser, restoring the line to safety without requiring production to be shut in.
