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.
