Investigation of Tendon Fatigue of Tension Leg Platform Wind Turbine

摘要

Tension leg platform wind turbine concept is preferred for intermediatewater depths. In this work, the coupled simulations of wind turbine,TLP foundation, and tendons is performed using SESAM and FASTprogram for a conceptual design for South China Sea. The tendontension of the TLP wind turbine in time series is analyzed to investigatethe effect of the second order hydrodynamics. In addition, the tendonfatigue life of is calculated with rainflow method with and withoutaccounting for the second order hydrodynamics, whose effect on thetendon fatigue of TLP wind turbine system is investigated.
