The assessment of ocean wave energy along the coasts of Taiwan

YH Lin, MC Fang – China Ocean Engineering, 2012


The wave energy resource around the coasts of Taiwan is investigated with wave buoy data covering a 3-year period (2007–2009). Eleven study sites within the region bounded by the 21.5°N–25.5°N latitudes and 118°E–122°E longitudes are selected for analysis. The monthly moving-average filter is used to obtain the low-frequency trend based on the available hourly data. After quantifying the wave power and annual wave energy, the substantial resource is the result of Penghu buoy station, which is at the northeastern side of Penghu Island in the Taiwan Strait. It is investigated that the Penghu sea area is determined to be the optimal place for wave energy production according to its abundant resource of northeasterly monsoon waves, sheltering of the Taiwan Island, operation and maintenance in terms of seasonal conditions, and constructability of wave power devices.
