Improvement of the estimation accuracy of the wave load is necessary to realize a rational ship structure design. However, a rational method has not been established to determine the operation limit which influences the wave loads. In this study, the ship encounter sea condition including the operation in wave such as wave direction and ship speed, and the wave loads acted on actual ships were investigated using AIS data and wave hindcast data, and following were confirmed.
The maximum significant wave height in North Atlantic sea by wave hindcast is not significantly differ from IACS Recommendation No. 34.
Significant wave height that ships encountered is reduced by about 10–20% owing to the seamanship of storm avoidance.
The maximum wave loads of individual ships were estimated for container ships, tankers and bulk carriers using the strip method. It is clarified that the vertical bending moment in waves, which is estimated to have acted in the actual sea conditions, is almost below the design load.
