Abstract
The disclosure provides a blowout preventer system including: a hydraulic circuit, a blowout preventer including a ram having an open port and a close port, a hydraulic fluid tank, a hydraulic fluid pump, and a control valve. The hydraulic circuit includes: a first accumulator, a first valve, and a second valve. The control valve is coupled to the open port, the close port, and the hydraulic fluid tank. The first accumulator is coupled to the control valve by way of the first valve and to the close port by way of the second valve. The first valve allows hydraulic fluid to flow from the control valve to the first accumulator but prevents hydraulic fluid from flowing back to the control valve. When the control valve is in the open position, the second valve is closed, and when the control valve is in the close position, the second valve is open.
