Abstract

The development for renewable energy is highly valued, and offshore wind energy is one of the few kinds of sustainable energy which can be operated reliably and harvested efficiently. The feasibility evaluation of the offshore turbines should include an assessment of the possible long-term morphological evolution, and an assessment of the local erosion caused by the turbine foundations. In this paper, a numerical model is presented for the simulations of the morphological changes in large coastal area and local seabed evolutions near turbine foundation. The target wind farm is located at the Fang-Yuan coast, Chang-hua County in Taiwan western Coast. We investigated the influence of an offshore wind farm on the large-scale morphological evolution of the seabed with the jacket type foundation. The results show that there is slight influence for large coastal area around the offshore wind turbine foundation.
