The stability of some currently used wave parameters

Confidence interval of the ‘single-moment’ fatigue damage calculated from an estimated power spectral density

“…The importance of the statistical variability of an estimated power spectrum and its spectral parameters seems to be well known in the field of ocean engineering [15][16][17][18][19]. But surprisingly it has received no attention in the field of structural durability, where the statistical variability characterising the fatigue damage computed from an estimated power spectrum is not considered by spectral methods.…”

“…The quantity represents the mgf of the chi-square random variable , as exemplified in Eq. (15). Substituting in Eq.…”
