Abstract:
Method and recharging mechanism for resetting a pressure in a low pressure recipient. The recharging mechanism includes a low pressure recipient configured to have first and second chambers, the first chamber being configured to receive a hydraulic liquid at a high pressure and the second chamber being configured to include a gas at a low pressure. The recharging mechanism further includes a valve fluidly connected to a first port of the first chamber; a pumping device fluidly connected to a second port of the first chamber; and a blowout preventer (BOP) section fluidly connected to the valve and configured to close or open a ram block. The pumping device is configured to evacuate the hydraulic fluid from the first chamber of the low pressure recipient when the valve closes a fluid communication between the first port of the first chamber and the BOP section.
