Abstract
A ship comprising: approximately sinusoidal waterlines; and a surface extending from the transom stern at the design waterline plane to the base plane at about L/3 from the bow and defining an angle between the base plane and an oblique plane, the oblique plane being defined by: a line at the intersection of the transom stern and the design waterline plane and a point located on the surface at about 0.2 L from the transom stern; and a turret along the middle line plane.
Claims7
A self-weathervaning, self-propelled marine production platform having a bow and a transom stern, a longitudinal length L, a middle line plane, a base plane, and a design waterline plane, the platform comprising:
- approximately sinusoidal waterlines;
- and
- a surface extending from the transom stern at the design waterline plane to the base plane at about L/3 from the bow and defining an angle between the base plane and an oblique plane, said oblique plane being defined by:
- a line at the intersection of the transom stern and the design waterline plane;
- and
- a point located on said surface at about 0.2 L from the transom stern;
- and
- a production-mooring turret located at a self-weathervaning position along the middle line plane.
