Publication number: 20170247984Abstract: A weak link arrangement (1) designed for location on an umbilical (6, 7) extending on the seabed between respective structures potentially subjected to environmental hazards, like being snapped by an iceberg, which umbilical includes communicating fluid pipes and electric cables, is described. The weak link arrangement (1) includes a seabed frame (2) supporting an umbilical having a weak link multiconnecting structure (3) (UTA) installed in line, which weak link multiconnecting structure (3) (UTA) ensures continuous communication through the fluid pipes and electric cables until emergency disconnection takes place. Such disconnection is initiated by accidental pull in the umbilical, which pull activates disconnecting means and cable severing means.Type: ApplicationFiled: October 15, 2015Publication date: August 31, 2017Applicant: Aker Solutions ASInventors: Bjørn PAULSHUS, Sigvard OMVIK

Patent number: 8001996Abstract: A composite pipe having at least one metal end piece (2, 3) with a free end and a non-metal tubular component (10). The tubular component (10) is coupled to the at least one end piece (2, 3) opposite of the free end of the end piece (2, 3), by means of at least one peripherally extending, axially acting groove (6, 7) that the non-metallic tubular component (10) engages. The non-metallic tubular component (10) generally comprises axial fibers (11) extending down into the at least one groove (6, 7).

Patent number: 6988340Abstract: An end termination for a tension leg of non-metallic materials like composite material is disclosed. The tension leg is constructed of a number of strands which constitute the load carrying elements of the tension leg. The strands are twisted (laid) about the longitudinal axis of the tension leg by a predetermined laying length and in turn each strand is constructed of a plurality of rods of composite material having embedded strength fibres. The rods are in turn twisted about each other like in a wire rope. The strands terminate into a receiving body that forms fixing points for the respective strands. The end termination comprises an embracing element that is spaced apart from the receiving body and keeps the strands together. Intermediate the embracing element and the receiving body the strands extend less radial restriction and in a substantially natural direction towards and into apertures in the receiving body.Type: GrantFiled: December 20, 2001Date of Patent: January 24, 2006Assignee: Kvaerner Oilfield Products ASInventors: Bjørn Paulshus, Morten Rengman Mørck
