Evaluating the dynamics of tension mooring supported tidal turbines

Research output: Contribution to conferencePaper

Abstract

This paper reports the design of a tidal turbine station keeping system based on the adoption of a tensioned mooring system and investigates potential capabilities of introducing dampening into the system and the capabilities to reduce the peak loads tidal turbines experience during operations in
high energy wave-current environments. A neutrally buoyant turbine is supported from a tensioned cable based mooring system, where tension is introduced by a buoy are 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 have been based on an inverted triple pendulum, responding to different sea state conditions in order to understand the response behavior of the system and the loads on blades in different flow conditions.
