SUBSEA INTERVENTION SYSTEM, METHOD AND COMPONENTS THEREOF

摘要

The subsea intervention system (SIM) includes a BOP module (10) and CT module (20). A tool positioning system (76) is used for positioning a selected subsea tool (22) stored within a rack (18) with a tool axis in line with the BOP axis, while a marinized coiled string injector (80) is moved by positioning system (81) to an inactive position. Power to the subsea electric motors (162) is supplied by an electrical line umbilical extending from the surface for powering the pumps (164), with the hydraulic system controlled by power control unit (198). The injector (80) preferably includes a pressure compensator roller bearing (220) and a pressure compensated drive system case (254).
