Abstract
A subsea termination head assembly adapted for both communicating and controlled load earning connection via a termination head to a subsea structure to be installed on the seabed, is described. The termination head allows a subsea cable, a power cable, a power umbilical or an umbilical, to be connected to the subsea structure before lowering them as a unit from a vessel and into the sea. The termination head assembly and subsea structure are to be lowered together while concurrently paying out the cable all the way to the seabed. The termination head is arranged to be hingedly connected relative to the subsea structure, which allows the termination head to pivot about a pivot axis in order to let the subsea cable adopt a natural catenary curvature in the sea during lowering thereof. The cable extends in a pigtail loop from the termination head and into the subsea structure. The pigtail loop is able to perform a “rolling motion” during such pivotal movement of the termination head.
