A subsea termination head assembly (1) adapted for both communicating and controlled load carrying connection via a termination head (4) to a subsea structure (3) to be installed on the seabed, is described. The termination head (4) allows a subsea cable (2), a power cable, a power umbilical or an umbilical, to be connected to the subsea structure (3) before lowering them as a unit from a vessel and into the sea. The termination head assembly (1) and subsea structure (3) are to be lowered together while concurrently paying out the cable (2) all the way to the seabed. The termination head (4) is arranged to be hingedly connected relative to the subsea structure (3), which allows the termination head (4) to pivot about a pivot axis in order to let the subsea cable (2) adopt a natural catenary curvature in the sea during lowering thereof. The cable (2) extends in a pigtail loop (L) from the termination head (4) and into the subsea structure (3). The pigtail loop (L) is able to perform a "rolling motion" during such pivotal movement of the termination head (4). |
