1. 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;
a first pump system comprising a first electric motor coupled to a first pump;
a second pump system comprising a second electric motor coupled to a second pump,
wherein the first pump system and the second pump system are fluidly coupled to the fluid reservoir;
at least one power source,
wherein the first pump system and the second pump system are electrically coupled to the at least one power source;
at least one valve fluidly coupled to the first pump system and the second 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;
instruct the at least one power source to provide power to the first pump system to cause the first pump system to pump the fluid from the reservoir to the at least one valve in response to the at least one input; and
instruct the at least one power source to provide power to the second pump system to cause the second 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.
