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 3):
The offshore floating facility of  claim 1 , further comprising a secondary operating device that is operable over the moonpool, wherein the secondary operating device is either movable with respect to the upper drilling deck for placement over one slot of the array of structurally distinct slots or fixed directly or indirectly to the upper drilling deck, wherein the array of structurally distinct slots allows positioning of the first riser below the primary operating device and positioning of the second riser below the secondary operating device at the same time that the first riser is positioned below the primary operating device so that drilling and production operations can be performed on, in, or through the first and second risers simultaneously.
