摘要： A deep ocean drilling system is disclosed for drilling offshore wells in extremely deep water using smaller and more economical drilling vessels. The system utilizes a reduced diameter drilling riser that reduces the size and cost of conventional floating drilling unit. The reduced diameter drilling riser is detached from the blowout preventer stack and repositioned and attached to a mud return assembly. Large diameter casing is lowered into the wellbore outside of the reduced diameter riser. Thereafter, the reduced diameter drilling riser is released from the mud return assembly and repositioned over and reconnected to the blowout preventer stack.

摘要： The invention consists of a floating production vessel operating on the surface of the sea with two or more risers connected between equipment or wells on the sea floor and the vessel or its equipment at the surface. The risers are rigid, jointed pipe with rugged field proven drill-pipe type connections. The arrangement, spacing, and support of the risers at the vessel and on the sea floor is such that the vessel, riser supports, and upper ends of the risers may be rotated from a neutral heading up to about 90 degrees in either direction without the use of a swivel or turret at the surface or sub-sea, and without damage to the risers or reducing the spacing between the risers unacceptably.
摘要翻译：本发明包括在海面上运行的两个或多个立管连接在海底设备或井之间的浮式生产船，以及船舶或其表面上的设备。立管是具有坚固的现场验证的钻杆式连接的刚性连接管。容器和海底上的立管的布置，间隔和支撑使得容器，提升管支撑，并且提升管的上端可以在任一方向上从中性标题旋转到大约90度，而不在表面或海底使用旋转或转塔，并且不损坏立管或者不可接受地减小提升管之间的间距。
