(54) Title: FLOATING OIL AND GAS FACILITY WITH A MOVABLE WELLBAY ASSEMBLY (57) : A mobile offshore drilling unit is converted to provide drilling, 30 completion and workover access to multiple dry tree wells from a drilling derrick 40 to allow production and export of oil and gas from high pressure, high temperature 20 reservoirs in deep offshore waters. Existing practice has been for the drilling der- 230 rick on a production platform supporting dry tree wells to be moved over a fixed 50 well slot. The present invention provides a movable wellbay that supports multiple 105a 105b 120 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 lon e converted facility to drill, complete, maintain, improve and produce from subsea wells through dry trees.
