Abstract
Design of floating wind turbines currently attracts increasing attention as deployments tend to move in deeper waters. This paper documents a procedure for structural integrity assessment of the H2OCEAN multi-modal offshore wind-wave energy converter based on the combination of local stress spectra and structural dynamic stress transfer functions. The complexity of coupling dynamic effects due to the combined effect of wind, wave and operational loads is discussed. Stochasticity of inputs to this procedure (loads and resistance) is also considered in a systematic way of assessing the fatigue limit state through concepts of structural reliability analysis, allowing further optimization of inspection and maintenance planning.
