Support Arches are used to protect the bending radius of a line as the line is being deployed down the side of a riser pipe. Support Arches can be used in conjunction with ABCO Subsea’s Roller Sheaves in a storm loop configuration. Support Arches stab into a Telescopic Joint fastened around a riser pipe in a moon pool, securing the Support Arch to the riser pipe.


ABCO Subsea has been manufacturing Support Arches and storm loop assemblies since 2008. Support Arches can accommodate a line with up to a 5.5” outside diameter, or several lines with a combined outside diameter of 5.5”. The Support Arches can maintain a minimum bend radius ranging from 18”-36”.


ABCO Subsea’s Support Arches are custom-designed to fit each client’s unique needs. ABCO Subsea performs extensive in-house factory acceptance testing on its Support Arches before delivering the final product to our customer.
