Closing unit system for a blowout preventer

A closing unit system for a blowout preventer (BOP) stack, the closing unit system comprising:

• a fluid reservoir that stores a fluid at atmospheric pressure;
• at least one pump system comprising an electric motor coupled to a pump,
• wherein the at least one pump system is fluidly coupled to the fluid reservoir;
• at least one power source,
• wherein the at least one pump system is electrically coupled to the at least one power source;
• at least one valve fluidly coupled to the at least one pump system via a closing unit hose assembly;
• and
• one or more processors configured to:
• receive at least one input indicative of an instruction to control an actuator associated with the BOP stack;
• 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,
• wherein the at least one valve is fluidly coupled to the actuator associated with the BOP stack.
