The research of ocean waves has been important, not changing since the Age of Great Voyages, because we can't still get the complete knowledge of them. The objective of this research is to develop the fast calculation process of ocean waves, which includes the customized hardware as well as the software algorithm. The authors have realized the real time simulation of many types of ocean waves by the parallel computing system which consists of a PC (Personal Computer) and DSPs (Digital Signal Processor). The real time wave synthesis executing in DSPs is also developed. The methods are applied to a wave simulator as well as a wave maker.

At present stage the analytical design of wave tolerance for floating structures and vessels is still imperfect due to the mutually complex and nonlinear phenomena between structures and waves. Wave tolerance design is usually carried out through iterative evaluations of results from model tests in a wave basin, and this is done in order to reach a final structural design. The wave generation has then become an important technology in the field of the coastal and ocean engineering. This paper summarizes the facilities of a test basin and a wave maker in Japan and also surveys the methodology of the generation of ocean waves in a test basin
