Abstract: A closing unit system for a blowout preventer (BOP) stack includes a first fluid reservoir, a first power source, a first pump system fluidly coupled to the first fluid reservoir and electrically coupled to the first power source, and a valve manifold fluidly coupled to the first pump system via a closing unit hose assembly and configured to couple to the BOP stack. The closing unit system also includes one or more processors that are configured to receive an input indicative of an instruction to adjust an actuator associated with the BOP stack, and instruct the first power source to provide power to the first pump system to cause the first pump system to pump a fluid from the first fluid reservoir to the valve manifold in response to the input.

Abstract: An accumulator system includes a chamber configured to receive a first fluid, a piston configured to move within the chamber to pressurize and drive the first fluid out of the chamber, a driving shaft coupled to the piston, a screw adapter coupled to the driving shaft, a plurality of anti-rotation shafts, and an electric actuator configured to couple to the screw adapter and to rotate the screw adapter to axially move the driving shaft. The piston includes a body defining a first aperture and a plurality of counterbores. The driving shaft is coupled to the piston via the first aperture. The piston is configured to slide over the plurality of anti-rotation shafts via the plurality of counterbores.

Abstract: A closing unit system for a blowout preventer (BOP) stack includes a fluid reservoir that stores a fluid at atmospheric pressure, at least one pump system fluidly coupled to the fluid reservoir, and at least one power source electrically coupled to the at least one pump system. At least one valve of the closing unit system is fluidly coupled to the at least one pump system and to an actuator associated with the BOP stack. The closing unit system also includes one or more processors configured to receive at least one input indicative of an instruction to control the actuator, and instruct the at least one power source to provide power to the at least one pump system to cause the at least one pump system to pump the fluid from the reservoir to the at least one valve in response to the at least one input.
