Abstract

The objective of this study was to adequately examine potential wave fields, flow fields, and suspended load changes in different wind turbine foundations. Accordingly, this study applied the hydrodynamic model to simulate waves, currents, and suspended load in the study area. The simulation results are based on the assumption that dredging and rubble bed trimming were performed for 8 h and that the per foundation setting operation was completed in 2 h. The influence on the tripile and jacket was larger than that on the monopile, and the influence time was longer. However, due to the influence of tidal currents on the sea, the suspended load also became more acceptable than the initial concentration. From a macroscopic perspective, the different foundations did not sufficiently affect the study area. From a microscopic perspective, changes in the suspended load were only limited to areas surrounding the piles after the installation of the wind turbines.

Highlights

  • Favorable locations for developing wind farms have been exhausted, and wind turbine generators because considerable noise engendered by wind shear; establishing offshore wind farms will become a future trend for Taiwan

Summary

Introduction

Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Due to the increasing environmental awareness in recent years, people have begun to consider the problems of air pollution and nuclear waste treatment caused by fossil fuels and nuclear power generation, respectively. Determining economically beneficial and environmentally friendly power generation methods has become an imperative task for Taiwan. Over the past 10 years, Taiwan has been actively developing terrestrial wind farms. A total of 24 wind farms have been established on the island. Favorable locations for developing wind farms have been exhausted, and wind turbine generators because considerable noise engendered by wind shear; establishing offshore wind farms will become a future trend for Taiwan
