Patent number: 10153626Abstract: A subsea installation tool for installing a flexible body, e.g. a subsea fiber cable on a seabed from a surface vessel, and an associated method for installing the flexible body on the seabed is provided. The installation tool includes a tensioner that may be coupled to the flexible body to actively pull it down, thus increasing tension in an upper section of the cable from the installation vessel to the installation tool. High tension in the upper part of the cable gives good control even in strong sea currents. At the same time the tensioner enables lower tension in the bottom part cable from the installation tool to the seabed, giving good control of the touchdown position on the seabed.Type: GrantFiled: April 16, 2012Date of Patent: December 11, 2018Assignee: OPTOPLAN ASInventor: Arne Berg

Publication number: 20100329791Abstract: The invention relates to a method and an apparatus for retrieval and deployment of a cable distribution network comprising a main cable and secondary cable sections branched off from the main cable. Retrieval and deployment of the cable network is accomplished by use of a multi-reel system having separate primary and secondary reels for accommodating sections of the main cable and the secondary cable sections. Since the primary and secondary reels are independently rotatable, the cable network can be installed efficiently and reliably.Type: ApplicationFiled: June 25, 2009Publication date: December 30, 2010Inventor: ARNE BERG
