PRODUCTION UNIT FOR USE WITH DRY CHRISTMAS TREES

摘要

The invention concerns a floating platform for drilling, production, storage of oil, comprising: a hull / body (1), at least one rigid vertical riser (4), at least one connecting part (6), wherein at least one of the at least one connecting part (6) is connected to one of the at least one riser (4), a moonpool (3) allowing suspension of the at least one riser (4) close to the center of the hull (1) where the influence of rolling and ramming movements is at a minimum, and where the at least one riser (4) and its corresponding connecting part (6) are particularly protected against external forces such as waves, a first deck (11) positioned on top of hull (1), process tools (10) on or above the first deck of the hull (1), at least one flexible tube or line connection (7) positioned between the process tools (10) and the connecting part (6) for the at least one riser (4), and at least on lip ("bilge box") (2) arrange d at or close to the lowest part of the hull (1) to reduce movements that may be triggered by external forces such as waves. The platform is further characterized in that the at least one connection tool (6) arranged between the process tools (10) and at least one of the at least one riser (4) comprises at least one dry Christmas tree (6) allowing for the installation of said riser (4) to be performed above a waterline of the platform, and that the at least one dry Christmas tree (6) is connected to the process tools (10) via the at least one flexible tube or line connection (7).
