Joint integrity specialist Hydratight employed a Morgrip connector to repair a damaged super duplex pipe located within the constrained space of a Troll C subsea manifold off Norway. The company was called in by Statoil when it was discovered that a subsea tree mandrel and its 6in supporting pipe had been pulled out of position during an operation, overloading the pipe and forcing the shutdown of an associated 10in line in 340m of water. ‘At that depth solutions were limited,’ said Hydratight application engineer Mark Fisher.
A 6in super duplex Morgrip end-connector (pictured) had to be specially engineered to fit within the significant physical constraints of the manifold.
