The first offshore wind farm in Taiwan started commercial operation at the end of 2019. The Taiwanese government aims to increase the installed capacity of offshore wind power up to 5.7 GW by 2025 as there are abundant wind resources on the west coast of Taiwan. However, natural hazards such as typhoons and earthquakes are a constant threat. It is important to ensure the safety of wind turbines and their supporting structures. Therefore, a 1/25 scale model of an offshore wind turbine with a jacket foundation was tested in NCREE Tainan Laboratory. The tested model includes wind turbine tower, and a jacket-and-pipe foundation, which was installed in the shear box filled with water and sand to simulate seabed environment. It was excited by white noise, sinusoidal excitation, and near-fault artificial earthquakes. The analysis of testing data is still underway, and expected results include structure-soil interaction, soil liquefaction, and shock absorption technique for wind turbine with jacket foundation. |
