ELECTRICAL POWER STORAGE AND PRESSURISED FLUID SUPPLY SYSTEM

摘要

The invention relates to an electrical power storage and pressurised fluid supply system for use in the oil and gas exploration and production industry. A fluid operated apparatus associated with a well incorporating such a system; a method of carrying out a well function; and a method of storing electrical power and supplying fluid under pressure to a fluid operated apparatus associated with a well is also disclosed. In an embodiment of the invention, there is disclosed an electrical power storage and pressurised fluid supply system (10) for use in a subsea environment in the actuation of fluid operated apparatus such as a BOP (48) associated with a well (59). The system comprises an electrical power storage unit (12); at least one electric motor (18, 18') coupled to and powered by the at least one electrical power storage unit; and at least one pump (20, 20') coupled to and driven by said electric motor, said, pump adapted to supply fluid under pressure to the fluid operated apparatus for carrying out a function subsea.
