Abstract
Methods and systems are provided for nautical stationkeeping of free-floating objects. In one example, a method includes adjusting translational motion of a body freely floating in water by rotating the body. The translational motion may be adjusted, for instance, to maintain the body within a geographic area. In certain examples, the adjustment of the translational motion may be realized via a Magnus effect induced by rotating the body. The body may be configured as, for example, a free-floating object such as a wave engine.
Claims11
An unmoored ocean faring wave energy converter, comprising:
- a hull having a draft of a length greater than a length of a largest horizontal width, the hull including a bulbous enclosure having substantial symmetry about a vertical axis and an open tube protruding downwardly therefrom;
- a reservoir within the bulbous enclosure adapted to adjust a buoyancy of the hull through ingress and egress of water received via the open tube;
- and
- a first fluid conduit extending outwardly from a surface of the bulbous enclosure, said first fluid conduit including a first fluid outlet for expelling water at a direction tangential to a surface of the bulbous enclosure;
- wherein expulsion of said water through the first fluid conduit imparts a rotational force on the wave energy converter.
An unmoored ocean faring wave energy converter, comprising:
- a hull having a draft of a length greater than a length of a largest horizontal width, the hull including a bulbous enclosure having substantial symmetry about a vertical axis and an open tube protruding downwardly therefrom;
- a reservoir within the bulbous enclosure adapted to adjust a buoyancy of the hull through ingress and egress of water received via the open tube;
- and
- a plurality of adjustable flaps extending outwardly from a surface of the bulbous enclosure, said adjustable flaps configured to impart a rotational force on the hull.
