隨著傳統能源消耗帶來的環境問題日益嚴重，各國正積極尋找替代能源，風力發電作為低污染能源，受到了廣泛開發。由於陸地風場的飽和，各國正積極轉向開發離岸風能，離岸風能具有低污染、低成本和對環境衝擊較小的優點，因此成為各國發展的重要方向。台灣海峽西部海域風能條件優良，為台灣離岸風能開發，提供了廣闊的發展空間，相比歐洲等成熟的離岸風能產業地區，台灣在技術、經驗和環境因素上仍面臨挑戰，需持續努力提升技術和累積經驗，以實現離岸風能產業的發展和成熟。
本研究透過Abaqus有限元素分析軟體，建立10 MW套管式及單樁式離岸風機數值模型，並考慮不同支承和土壤模型，如固定支承、根據API建立之土壤彈簧、有限元素土壤和有限元素加無限元素混和土壤等四種模型，與文獻中的頻率進行驗證，以驗證數值模型之合理性，並進行載重分析，利用Abaqus/Aqua模組模擬風機受環境載重之結構行為，將套管式離岸風機施加風力、波浪、海流等環境載重下，進行不同模型間，結構行為差異之探討，研究成果結論如下。
頻率驗證發現，固定支承模型在高模態頻率誤差逐漸放大，而土壤彈簧和有限元素土壤模型的誤差為可接受之模型，有限元素土壤加上無限元素土壤的模型更接近實際狀況，可使高模態頻率降低。離岸風機受環境載重考慮樁土互制效應會增加塔頂位移，考慮不同基礎模型會直接影響結構變形，四個模型依時間成本及精準度的綜合考量下，可優先選擇土壤彈簧模型。

As the environmental problems caused by the consumption of traditional energy become more serious, countries around the world are actively seeking new alternative energy. Wind energy is a clean energy that is being actively developed in many countries. As onshore wind farms become saturated, countries are now turning to developing offshore wind farms. Offshore wind energy, as one of the most representative forms of renewable energy, is characterised by low pollution, low cost and minimal impact on the environment, making it an important direction for national development. The western waters of the Taiwan Strait have excellent wind energy conditions, providing great development for Taiwan's offshore wind energy industry. Compared to regions such as Europe, which already have a mature offshore wind industry, Taiwan faces significant challenges. These include technology, experience and environmental factors. It is hoped that Taiwan's offshore wind industry will mature through continuous efforts to improve technology and experience.
This study uses the finite element analysis software Abaqus, with reference to models from the literature, to establish numerical models for 10 MW jacket and monopile type offshore wind turbines. Four different foundation models are considered: fixed end, soil springs established according to API specifications, finite element soil, and a hybrid finite and infinite element soil model. To ensure the reasonableness of the numerical models and to simulate the load analysis, these models are validated against frequencies reported in the literature. The Abaqus/Aqua module is used to simulate the structural response of wind turbines under environmental loads, including wind, waves and currents. The study looks at the differences in the structural response of the different models when subjected to these environmental loads.
