...Haiyan Long; Geir Moe The fatigue assessment of support structures is one of the most significant challenges in the design of offshore wind turbines (OWT). Fatigue analysis can be conducted in either the time-domain or the frequency-domain. The advantage of frequency-domain analysis is its time...

... catenary anchor leg mooring (CALM) buoy is of practical interest for the mooring system design. Experimental model tests and numerical simulations in the time- and frequency-domains have been used to describe and predict the CALM buoy behavior under environmental loadings. fatigue frequency-domain...

.... In what follows, the linearized equations will be derived for fully coupled analysis of the simplified system. The nonlinear equations of motion must be linearized for a frequency domain analysis. The nonlinearities include the two restoring forces in the springs and the drag force on the lines...
