Asset integrity management is critical for offshore structures that are constantly working in an aggressively harsh environment that exposes them to corrosion and wear both above and below the water. Our composite solutions were developed specifically to contend with corrosion and have been used for decades to repair damage on decks, in the splash zone, and below the water line.

CSNRI’s engineered composite repairs are effective on cracks and leaks in addition to corrosion damage and can be applied on topsides, risers and caissons as well as cooling lines, deluge lines, firewater lines and produced water lines. Our industry-leading solutions are as effective on flat surfaces and straight runs of pipe as they are on complex geometry like tees, elbows and welded joints. From deck restoration and reinforcement to emergency leak containment and CUI repairs, CSNRI solutions get the job done without negatively impacting project economics or compromising safety.

Our structural strengthening products are AWWA C217 and ACI 440.2R-17 certified and are ready to use and simple to apply underwater with no field testing required, no pipe cutting or welding and no unplanned down time for high-consequence piping.
