SYSTEMS AND METHODS FOR PULLING SUBSEA STRUCTURES

摘要

A system (300) for pulling a subsea structure includes an adapter (320) configured to be mounted to an upper end of a subsea pile (110). In addition, the system includes an interface assembly (340) fixably coupled to the adapter. The interface assembly includes a first channel (349) configured to receive a flexible tension member (390) and a first chuck (361) disposed in the first channel. The tension assembly (380) includes a second channel (387) configured to receive the flexible tension member and a second chuck disposed in the second channel. Each chuck is configured to pivot about a horizontal axis between an unlocked position allowing the flexible tension member to move in a first axial direction and a locked position preventing the tension member from moving in a second axial direction that is opposite the first axial direction.
