Abstract
A tool for actuating a blow out preventer includes one or more connections for receiving hydraulic power from a remotely operated vehicle (“ROV”), a first pump for increasing pressure of an operating fluid for the blowout preventer (“BOP”), a second pump for increasing flow rate of the operating fluid, and a conductor for transporting the operating fluid to the BOP. The tool rapidly increases the pressure and flow rate of the fluid flowing to the BOP, and the BOP may be rapidly closed.
Claims20
A tool for actuating a blow out preventer (“BOP”), the tool comprising:
- one or more connections configured to receive fluid power from a remotely operated vehicle (“ROV”);
- a fluid powered high pressure pump fluidly connected to the one or more connections and configured to increase pressure of an operating fluid for the BOP;
- a fluid powered high flow pump fluidly connected to the one or more connections and configured to increase flow rate of the operating fluid, wherein the high flow pump is configured to pump the operating fluid to the BOP until a predetermined pressure is reached, wherein once the predetermined pressure is reached, the fluid power is shifted from the high flow pump to the high pressure pump via the one or more connections;
- and
- a conductor configured to transport the operating fluid to the BOP.
A method for actuating a blow out preventer (“BOP”), comprising:
- fluidly connecting a remotely operated vehicle (“ROV”) to a tool, wherein the tool includes a high flow pump and a high pressure pump;
- fluidly connecting the tool to the BOP;
- powering the high flow pump to increase a flow rate of an operating fluid pumped by the high flow pump to the BOP until a predetermined pressure of the operating fluid is reached;
- once the predetermined pressure of the operating fluid is reached, shifting power from powering the high flow pump to powering the high pressure pump to further increase the pressure of the operating fluid;
- and
- conducting the operating fluid from the tool to the BOP to actuate the BOP.
A system for actuating a blow out preventer (“BOP”), comprising:
- a remotely operated underwater vehicle (“ROV”), and
- a tool fluidly connected to the ROV, wherein the ROV is configured to power one or more pumps of the tool to increase pressure and flow rate of fluid from a fluid source to the BOP until the BOP is fully actuated, and wherein the tool is movable between a first position in which the tool is connected to the BOP and a second position in which the tool is disconnected from the BOP.
A method for actuating a blow out preventer (“BOP”), comprising:
- connecting an actuation tool to the BOP;
- supplying power from a remotely operated underwater vehicle (“ROV”) to the actuation tool;
- increasing a pressure and a flow rate of an actuation fluid pumped by the actuation tool;
- supplying the actuation fluid from the actuation tool to the BOP to actuate the BOP;
- and
- disconnecting the actuation tool from the BOP once the BOP is fully actuated.
