Abstract
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.
