SYSTEMS AND METHODS FOR PULLING SUBSEA STRUCTURES

摘要

A system for pulling a subsea structure includes an adapter configured to be mounted to an upper end of a subsea pile. In addition, the system includes an interface assembly fixably coupled to the adapter. The interface assembly includes a first channel configured to receive a flexible tension member and a first chuck disposed in the first channel. The tension assembly includes a second channel 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.

1. A system for pulling a subsea structure, the system comprising:
an adapter configured to be mounted to an upper end of a subsea pile; an interface assembly fixably coupled to the adapter, wherein the interface assembly has a longitudinal axis and includes a first channel configured to receive a flexible tension member and a first chuck disposed in the first channel, wherein the first chuck is configured to pivot about a horizontal axis between an unlocked position allowing the flexible tension member to move through the first channel in a first axial direction and a locked position preventing the tension member from moving through the first channel in a second axial direction that is opposite the first axial direction; a tension assembly moveably coupled to the interface assembly, wherein the tension assembly includes a second channel configured to receive the flexible tension member and a second chuck disposed in the second channel, wherein the second chuck is configured to pivot about a horizontal axis between an unlocked position allowing the flexible tension member to move through the second channel in the first axial direction and a locked position preventing the tension member from moving through the second channel in the second axial direction.
