Reduced J-tube riser pull force
摘要:
A method is provided for reducing the force required to move a pipe through a J-tube attached to an offshore platform by coating the pipe with hydrophilic polymer and then moving the pipe through the J-tube, or by introducing a solution of hydrophilic polymer and water into the J-tube and then moving the pipe through the J-tube.
