SUBSEA SYSTEM FOR SEABED OPERATIONS

摘要

Methods and systems relate to seabed operations, such as well intervention or capping, involving subsea equipment and subsea handling of the equipment, which may be associated with hydrocarbon wells or pipelines. A subsea system submerges during deployment and is landed on the seabed. The system may include a suspension assembly coupled to a frame structure for carrying equipment used in the operations. The deployment of the system may include deploying the frame structure with the equipment from a floating vessel connected to an anchored tether and moving the frame structure under water along the tether toward where anchored and the location for the seabed operations.

1. A subsea system for seabed operations, comprising:
a frame structure; buoyancy members attached to the frame structure for submergence of the system and controllable to set submerged weight of the system on the seabed; and a suspension assembly coupled to the frame structure for carrying equipment used in the operations and moveable by the suspension assembly relative to the frame structure.
