Bias in estimates of extreme significant wave heights for the design of ship structures caused by neglecting within-year wave climate variability

General-purpose FPSO acceleration load calculation error correction

“…When Zhou Yaohua [6] et al studied the sensitivity of excessive acceleration to the inertia of rolling motion, they proposed the lack of applicability of the empirical formula, studied its sensitivity to the accuracy of the moment of inertia by directly evaluating the numerical simulation method, and gave suggestions on the calculation method of moment of inertia for optimal design. A Mikulić [7] et al explored the consequences of extreme wave bending moment when studying the influence of wave climate variability on the prediction of extreme significant waves in ship structure design, and concluded that the influence of wave climate variability on extreme wave bending moment and that bending moment was as high as 10%. T Petranović [8] et al proposed a prediction method of vertical wave ultimate bending moment for passenger ships to calculate the most probable extreme wave bending moment at discrete positions of short-term sea state, which can be used to calculate the calculation of combined ultimate wave bending moment.…”
