Buoyant leg platform with retractable gravity base and method of anchoring and relocating the same |
摘要 |
A deep water platform, suitable for use as a hydrocarbon exploration or production facility in very deep offshore waters, and a method of constructing the same are shown. The platform is positioned on top of a buoyant leg structure. During normal drilling operations the platform is anchored by a gravity base tethered with pre-tensioned cables to the buoyant leg structure. According to the invention, the gravity base is retractable to permit the platform to be moved from site to site within a drilling region. Long distance relocation is also possible by retracting the gravity base, disassembling the platform, transporting the component parts, and reassembling the rig in a new location.
