In 2022, the International Association of Classification Societies (IACS) released a new version of the North Atlantic Standard Wave Data Rec. No. 34, in which the effects of the changes in the wave dispersion diagram, wave spectrum, and overrun probability on the linear wave load in the old and new wave environments are investigated based on the wave load calculation method in the frequency domain of the three-dimensional linear potential flow. The results show that the changes of the wave scattering map and the beyond probability calculation method in the new version of Rec.34 show a decreasing trend of wave load compared with the old version of Rec.34; the change of the wave scattering map has the largest effect on the wave load, which is around 15%, similar to the results of considering the new wave environment, and the remaining two have an effect of 5% or less. It can be seen that the change of wave dispersion map under new wave environment is mainly caused by the change of wave dispersion map, which in turn provides strong data support for the calculation of hull structure specification and direct strength analysis under new wave environment.
