摘要： 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.

摘要： This disclosure includes hydraulic apparatuses and methods for redundant actuation of a hydraulic device. Some apparatuses include a hydraulic device having a first hydraulic actuator and a second hydraulic actuator, wherein each of the first and second hydraulic actuators comprises at least a first hydraulic cavity, a second hydraulic cavity, and a piston. Some apparatuses also include a controller coupled to the hydraulic device. In some embodiments, the controller is configured to receive hydraulic fluid from a fluid source via at least two parallel hydraulic lines coupled to the controller, select a first hydraulic line of the at least two parallel hydraulic lines, and transfer the hydraulic fluid from the selected first hydraulic line to a first cavity of the first hydraulic actuator to apply pressure to a first piston to actuate the hydraulic device.
