Abstract (en)
[origin: WO2018138511A1] The invention relates to a method and apparatus for laying a length of subsea cable from on-board a vessel. The method comprises the steps of releasing the length of cable from the vessel wherein the step of releasing the length of cable comprises the steps of supporting the cable on a portion of on-board cableway, extending a portion of said cableway over-board the vessel and tilting a portion of said extended cableway relative to the portion of on-board cableway. This allows a length of cable to pass over the resulting extended and tilted portion of said cableway toward the seabed whilst in supported engagement with the extended and tilted portion of said cableway. A method and apparatus of moving the location of a cable bight point along a length of cable suspended between a vessel and the seabed is also provided. A cable recovery, repair and re-laying service is also provided.
