Abstract

An articulated type supporting structure for an offshore wind energy turbine, to suite Indian offshore conditions (east cost), is designed and analysed. Static as well as nonlinear coupled dynamic analysis is done to assess the performance of the proposed tower. The numerical investigation is carried out using an available finite element computer program specially suited for complaint offshore structures. A wave force model with diffraction-radiation loading on larger members and Morison loading on the slender members is adopted for computing the nonlinear dynamic response of the structure. The dynamic responses are presented in the form of Response Amplitude Operators. Fatigue analysis of the structure is carried out to estimate the fatigue life of the structure.
