Patent ID: 11339788

Abstract:
This disclosure includes subsea pumping apparatuses and related methods. Some apparatuses include one or more subsea pumps, each having an inlet and an outlet, and one or more motors, each configured to actuate at least one pump to communicate a hydraulic fluid from the inlet to the outlet, where the subsea pumping apparatus is configured to be in fluid communication with a hydraulically actuated device of a blowout preventer. Some subsea pumping apparatuses include one or more of: a desalination system configured to produce at least a portion of the hydraulic fluid; one or more valves, each configured to selectively route hydraulic fluid from an outlet of a pump to, for example, a subsea environment, a reservoir, and/or the inlet of the pump; and a reservoir configured to store at least a portion of the hydraulic fluid. Some apparatuses are configured to be directly coupled to the hydraulically actuated device.
