Fig. 9 (a) Maximum stress and strain values for the respective load
cases obtained from the FE model, (b) for each load case, the number of
fatigue cycles sustained by the OWT in the 20 years of operation
(ni) is shown by the marker points and the number
of cycles that the structural material (S355) can withstand before
fatigue failure occurs (Ni) is shown by the
dotted line, (c) fatigue damage caused by individual load cases and the
cumulative fatigue damage according to Minor’s method.
