Abstract:
A mobile offshore drilling unit is converted to provide drilling, completion and workover access to multiple dry tree wells from a drilling derrick to allow production and export of oil and gas from high pressure, high temperature reservoirs in deep offshore waters. Existing practice has been for the drilling derrick on a production platform supporting dry tree wells to be moved over a fixed well slot. The present invention provides a movable wellbay that supports multiple top-tensioned subsea well tieback risers, which may be positioned directly below the derrick's rotary table and/or beneath another operating device. The use of top-tensioned subsea well tieback risers supported by the movable wellbay allows the converted facility to drill, complete, maintain, improve and produce from subsea wells through dry trees.

Claim (Index 15):
The system of  claim 12 , further comprising hydraulic lifting or pumping equipment located at a seabed or within one of the one or more subterranean oil and/or gas wells, wherein the top ends of each riser of the set of two or more risers can be moved by moving the wellbay assembly laterally and transversely for providing vertical access to the hydraulic lifting or pumping equipment through each riser of the set of two or more risers.
