Method and system for recovering, and displacing fluid from, a pipe |
摘要 |
In one aspect, the present invention relates to a method for displacing fluid from a pipe. The method includes engaging a fluid-displacement system with the pipe. A displacement agent is pumped into the pipe via the fluid-displacement system. Fluid present within the pipe is displaced by the displacement agent. The pipe is manipulated in a desired manner. |

1. A method for displacing fluid from a pipe, the method comprising:
engaging a friction-pin unit with the pipe, the friction pin unit comprising a plurality of friction pins extending radially from a shaft, the plurality of friction pins being angulated relative to the shaft; pumping a displacement agent into the pipe via the fluid-displacement system; displacing away from the friction-pin unit, a fluid present within the pipe; and lifting the pipe via a recovery head attached to the friction-pin unit. |
