Kabelindtrækningssystem og fremgangsmåde til offshore-konstruktioner

摘要

A cable pull-in system for offshore structures (1) of the type having a hollow interior extending from the sea bed to above the surface of the water and an entry hole (2) in the external wall of the structure. The system comprises an entry hole protection unit (3) comprising a frame (4) equipped with magnets (6) arranged to be attached to the external wall of the structure (1) at entry hole (2) by an ROV. The entry hole protection unit (3) further comprising an elongated, hollow bend stiffener section (5) arranged to protrude through entry hole (2) when frame (4) is attached to the external wall. The system yet further comprising an elongated bend stiffener assembly (7) within the interior of which is arranged an elongated cable member (10), said elongated bend stiffener assembly being equipped with radial sealing members adapted for engaging the interior of bend stiffener section (5). The elongated bend stiffener assembly is pulled though the protection unit and up to a hangoff point above the water surface.
