SYSTEM AND METHOD FOR PERFORMING INTERVENTION OPERATIONS WITH A SUBSEA Y-TOOL

摘要

A technique utilizes a Y-tool (22) mounted at a subsurface installation (24) for subsea intervention operations. The Y-tool comprises a guide branch (30) and an open water branch (28) that each allows movement of intervention tools to the subsea installation. A tubular guide member can be coupled to the guide branch to enable movement of equipment down through the tubular guide member and into the Y-tool. Alternatively or in combination, other equipment can be moved down through the open water and into the Y-tool through the open water branch. The Y-tool further facilitates deployment of conveyances through the tubular guide and the guide branch to enable engagement of the conveyance with an intervention tool deployed through the open water and into the open water branch of the Y-tool.
