Offshore CompoSol® Encap
North Sea 1" Off Take Valves
An offshore platform operator in the North Sea had an integrity issue with an off take valve. A 24” Prover Loop System had a severely corroded 1” off take valve. External corrosion had caused wall loss down to 1mm and it was not thought possible to carry out hot work surface preparation on the significantly reduced wall thickness without the risk of perforating the substrate. IMG Composites were approached to provide a solution, CompoSol® Encap.
IMG Composites technologies allow repairs to be undertaken using surface preparation standards St 2 to SA 2.5. This technology means that the repairs can be carried out without causing further damage to already weakened systems. A saddle repair was designed using the CompoSol® Encap repair system. This repair was carried out while the line was still “Live", eliminating the need for any loss of production through shutdown.
