Abstract

See full text

A riser displacement and cleaning tool assembly (10) comprises a running tool (8) attachable to a work string (11), and a fluid displacing body (1) supported upon the running tool. The fluid displacing body has a head portion (6) provided with an opening (12) to accommodate relative movement of the fluid displacing body with respect to the work string, and also has flexible wiper elements (2) providing dynamic sealing contact with adjacent surfaces of the work string and a riser (20). The fluid displacing body has a skirt (5) depending from the head portion and enclosing a chamber (7) for receiving a fluid. The fluid displacing body is adapted to sealingly engage the riser and the string and is selectively releasable from an initial configuration where the fluid displacing body is supported by the running tool to an operational configuration where the fluid displacing body is axially displaceable from the running tool by introduction of a fluid to the chamber.
