- Abstract
- This thesis reports on the performance and interactions of a tidal turbine and station keeping systems based on the adoption of a tension mooring system in different sea states. The capabilities of introducing damping are being investigated to reduce the peak loads that tidal turbines experience during operational life in high energy wave-current environments and extreme sea states. A neutrally buoyant turbine is supported from a tension cable based mooring system, where tension is introduced by a buoy fully submersed in water. The loading on the turbine rotor blades and buoy are calculated using a wave and current coupled BEMT. The modeling algorithm developed is based on an inverted triple pendulum, responding to different sea state conditions to understand the system response behavior and the blade load in different sea states, including extreme conditions. The results show the tension mooring system reduce speak thrust loading on the turbine, but it was found that there are certain limitation when using this design in extreme waves conditions.
