Plug tooling package with integrated sequence valves |
摘要 |
A device and method of handling a plug in a tubing hanger includes a pressure actuated sequence valve that has multiple outlets. Hydraulic fluid from a remotely operated vehicle (ROV) provides hydraulic fluid that selectively flows through the valve for operating a tool that handles the plug. The valve outlets are ported to separate lines for operating different functions of the tool. Flow to a specific outlet occurs by sequencing the valve to a corresponding position, where the valve is sequenced by changing pressure of the hydraulic fluid. The sequence valve is disposed in a piston that is axially movable within the tool. A stroking rod attaches to the piston, and is actuated by diverting flow to sides of the piston. |

1. A tool for handling a plug in a subsea wellhead assembly comprising:
a tool main body having a cylinder in selective fluid communication with a fluid source; an end effector having a latch in selective engagement with the plug and a coupling assembly in selective mechanical cooperation with a latch assembly in the plug; a piston moveably disposed within the cylinder; a stem connected between the piston and the end effector, so that when fluid is introduced into the cylinder the end effector is axially moveable with movement of the piston; and a pressure controlled sequence valve in the piston that is in selective fluid communication with the latch and the coupling assembly. |
