Wave induced motions limit the working time andsafety of many offshore operations, e.g. crane lifts, LNG transfers,and helicopter landings. This paper details recent efforts todeterministically predict ocean surface waves using measurementsfrom the WaMoS II. The WaMoS II derives full 3-dimensionalsea surface elevation maps from nautical X-band radar images,yielding both sufficient resolution and range for a useful predictionhorizon. Validation of these surface elevation fields showsthey are in close agreement with sea surface elevation time seriesfrom wave buoys and motion reference units. Results from asimple propagation model are presented.
