CHARACTERISTICS OF LONG-TERM WAVE STATISTICS BY HIND-CAST FROM THE VIEW POINT OF BOW ACCELERATION RESPONSES

Long term wave statistics are important in the design of ships and offshore structures. Usually, visually observed data on board ship are used for such a purpose. However, the density of ship data is not uniform over the sea area and there is a problem over the accuracy of visual observation. New wave statistics of the North Pacific Ocean were published in 1992, and these include hind-casted long term wave data other than the conventional ship data and data measured by buoys. There are differences between the characteristics of ship and hind-casted data, but the effects on long term ship responses are not clear. This paper investigates the influences of the differences of wave statistics on long term ship motion and long term ship operability.
