SeAlign misalignment connector

SeAlign misalignment connector: Traditional subsea connections for rigid pipe spools require large bending moments for alignment during tie-in and connection, introducing high stresses in the piping. These stresses reduce the available capacity for operational loads from pressure and thermal expansion. SeAlign connection system, available both for make-up by divers and by ROV, allowing up to 3 degrees permanent misalignment, eliminates the tie-in bending moment. Using the SeAlign connection system opens for design of shorter tie-in spools. Significant savings on vessel time, vessel size and hardware cost can be realized. The benefit may also be realized as relaxed fabrication tolerances and simplified designs, e.g. for compact pigging loops and flow control modules.
