Abstract
In this study, a hydrodynamic model was used that includes the effects of wave–current interactions to simulate the wave and current patterns before and after offshore wind turbine installation in western Taiwan. By simulating the waves and currents after the offshore wind turbine was established, the waves and currents caused by the wind turbine were seen to have a limited range of influence, which is probably within an area about four to five times the size of the diameter (12–15 m) of the foundation structure. Overall, the analysis of the simulation results of the wave and current patterns after the offshore wind turbines were established shows that the underwater foundation only affected the local area near the pile structure. The wind farm (code E) of the research case can be equipped with about 720 cage cultures; if this is extended to other wind farms in the western sea area, it should be possible to produce economic-scale farming operations such as offshore wind power and fisheries. However, this study did not consider the future operation of the entire offshore wind farm. If the operation and maintenance of offshore wind farms are not affected, and if the consent of the developer is obtained, it should be possible to use this method to provide economically large-scale farming areas as a mutually beneficial method for offshore wind power generation and fisheries.
Highlights
Taiwan is a nation surrounded by ocean and has innate conditions for the development of marine applications
With the needs of economic development, the improvement of marine clean energy technology, the rise of marine recreational activities, the development of new type of coasts and oceans, and the increase in marine environmental awareness highlight the problems of space use
According to the selection results of the offshore wind power planning site selection [2], the Changhua sea area in western Taiwan has the capacity of offshore wind power installations as high as 62.6%, ranking first in Taiwan’s offshore wind power generation capacity distribution area
Summary
Taiwan is a nation surrounded by ocean and has innate conditions for the development of marine applications. According to the selection results of the offshore wind power planning site selection [2], the Changhua sea area in western Taiwan has the capacity of offshore wind power installations as high as 62.6%, ranking first in Taiwan’s offshore wind power generation capacity distribution area. This important area for the development of offshore wind power in the future is one of the most prosperous areas for offshore fishing operations in western Taiwan. In highly overlapping economic sea areas, the development of offshore wind power may impact the fishing and ecological environment in the same sea area
