Abstract : The patent relates to a station keeping apparatus for large floating ocean platforms. The arrangement makes use of wave energy acting on a platform supported by buoyancy derived from the submergence of long vertical columns. The oscillating horizontal component of stream flow in a predominant wave train yields a hydrodynamic force acting on such vertical columns if the latter possesses appropriately profiled cross-sections oriented to the wave flow pattern. A series of such columns can be arranged so that the resultant average hydrodynamic force vector will directly oppose the predominant wind and current vectors which tend to disturb the positioning of the platform.
