| 中文摘要 | 浮式風場的開發需要最適合應用的浮體類型,可供選擇的浮體類型主要包括半潛式、駁船和張力腿平台。每種 類型都有其獨特的優點和缺點,評估其運動性能對於確定其應用可行性至關重要。本研究分析了四種浮體設計的運 動特性:中央塔架半潛式平台(類似 VolturnUS 設計)、側塔半潛式平台(TaidaFloat 設計)、帶月池的方形駁船 (類似 Ideol 設計)和張力腿平台(類似 Float4Wind 設計)。本研究對每種浮體的尺寸進行了調整,以確保相互之 間可以公平比較,4 個模型均可用於支撐 15 兆瓦的風力發電機,分析過程使用 OrcaFlex 軟體進行模擬,在最大風浪 的設計載荷下,用台灣海峽新竹近海的環境數據,進行動態模擬。本研究對平台的靜水特性、水動力特性和動態運 動響應進行了評估和比較。分析結果表明,雖然張力腿式平台在起伏和縱搖運動方面幅度最小,但其漂移量幅度過 大,可能限制了其應用可行性。駁船式由於其較大的水線面面積增加了起伏剛度,導致起伏過於劇烈,性能較差, 且其起伏固有週期位於波浪能量集中區,導致其運動幅度最大。半潛式平台整體運動反應較為均衡。在兩艘半潛式 平台中,TaidaFloat 因其優異的垂蕩性能而脫穎而出,而 VolturnUS 在各種環境條件下,也表現出卓越的穩定性。基 於這些結果,從運動性能的角度來看,半潛式平台比起其他類型,更適合在台灣海峽等水域部署。 |
| 英文摘要 | Development of Floating Offshore Wind (FOW) farms requires identifying the most appropriate floater type for demo tests and commercial applications. Different types of floating concepts can be selected including semi -submersibles, barges, and Tension Leg Platforms (TLPs). Each type has its unique strength s and drawbacks. As-sessing their motion performance is essential for determining their feasibility. This research examines the motions of four floater designs: center-tower semi-submersible (inspired by VolturnUS), Side-tower semi-submersible (TaidaFloat), square barge with a moonpool (inspired by Ideol), and TLP (inspired by Float4Wind). The dimen -sions of each floater were calibrated to ensure some comparable characteristics. All models, designed to support a 15 MW wind turbine, underwent dynamic simulations using OrcaFlex under Design Load Cases 6.1, utilizing envi -ronmental data from offshore Hsinchu in the Taiwan Strait. Hydrostatic properties, hydrodynamic properties, and dynamic motion responses were assessed. The anal- ysis shows that while the TLP has smallest motions in heave and pitch, it allows excessive surge movements, potentially limiting its viability. The barge exhibits poor heave per-formance due to its large waterplane area that increases heave stiffness. Its heave natural period is adversely within the first-order wave excitation zone so that it has largest motions. Semi-submersibles offer a more balanced motion response overall. Between the two semis, TaidaFloat stands out for its excellent heave performance, while Voltur-nUS offers superior yaw stability under varying environmental conditions. Based on these results, semi-submersibles may be considered as the more suitable option for deployment in waters such as the Taiwan Strait. |
