Abstract

The research focus of this project is to design a methodology to reduce fatigue and peak structural loading experienced by support structures used for tidal stream converters. The methodology is based on the dynamic analysis of a towermonopile support structure for offshore wind turbines. A tuned mass damper (TMD) is implemented in the nacelle in fore-aft direction by correcting the discrete equation of motion of a fixed tidal turbine. Parameters such as added mass and viscous damping were thus incorporated in the mass and damping matrix to study the effects of using a TMD on a tidal energy converter. Both frequency and time domain analysis are presented to compare the TMD effect in different conditions. Moreover a sensitivity analysis in soil effect and different tower-monopile shape is presented. The result shows the influence of the TMD for a fixed tidal turbine when the structure suffers an instant impact and under unsteady continuous wave-current coupled forces.
