ABSTRACT:
Apparatus and method are provided for applying a force to a movable subsea member to move it into a preferred location for joining to a fixed member while the location of the movable member is monitored. Nozzles in the device are placed in the direction such that fluid exiting the nozzles creates a force so as to move the movable member into the preferred location. Fluid is pumped through the device and out through one or more nozzles. An environmental conductor may be tied back from a subsea wellhead using the apparatus and method by observing the location of the conductor over the subsea wellhead using a remotely operated vehicle (ROV) while fluid is pumped at the pressure and rate so as to move the conductor into position over the wellhead and lowering the conductor into the wellhead.
