The purpose of the paper is to investigate the influence of environmental and operational parameters on the long-term extreme vertical wave bending moment of a containership assuming rigid hull. The motivation is that assumptions built-in the IACS Recommendation No.34 “Standard Wave Data” need revision to account appropriately for design wave environment, speed reduction, course changes and wave energy spreading. The hydrodynamic analysis of two containerships is performed using the linear strip theory. Long-term distributions of vertical wave bending moments are computed using the standard procedure that considers the total lifetime response history as a series of short-term episodes. As the long-term distribution is highly dependent on the assumed environmental and operational parameters, their different combinations are considered. Obtained results are compared among themselves as well as with the IACS rule vertical wave bending moment. Such comparative study results in conclusions that are useful for the practical design of containerships.
