Abstract (en)
[origin: WO2016172345A1] Systems and methods for performing drill pipe motion compensation are disclosed. A system may include a drill pipe and a marine riser pipe, and the marine riser pipe may be configured to support the weight of a drill pipe. A pipe holder may be coupled to the drill pipe and the marine riser pipe and may be configured to suspend the drill pipe on the marine riser pipe. A drill pipe support system may be coupled to the pipe holder and the marine riser pipe. The drill pipe support system, together with the pipe holder, may be configured to transfer the weight of the drill pipe to the marine riser pipe. The system may also include a plurality of wires coupled to the marine riser pipe. One or more tensioners may be configured to compensate for motion on the drill pipe by controlling tension on one or more of the plurality of wires coupled to the marine riser pipe.
