Sažetak
Sources of uncertainty in calculation of lifetime vertical wave bending moment are concisely described. Joint probability distribution of significant wave heights and mean zero crossing periods is defined. Wave data from the wave atlas Global Wave Statistics (GWS) for the North Atlantic area are analysed. Extreme significant wave heights for different return periods are calculated. Associated wave steepnesses are estimated by extrapolation procedure. It is shown in the paper that data from GWS lead to considerable overestimation of actual wave steepnesses of extreme sea states. Implications of these overestimations on lifetime vertical wave bending moments are analysed. As a result of this study, the methodology to estimate more realistic extreme vertical wave bending moments is indicated.
