Abstract

In this study, we explore long-term trends in wave loads on cylindrical monopile structures in the North Atlantic Ocean off western Ireland, utilizing significant wave height and peak wave period values from ERA20 reanalysis data, calibrated against ERA5 from the Copernicus website. Wave excitation on fixed monopile structures is evaluated, with monopiles being an essential component for wave energy converters and offshore wind turbines. The benchmark 5MW National Renewable Energy Laboratory (NREL) fixed monopile turbine (OC3) is used to analyze drag forces, inertial forces, and fore-aft moments, revealing significant increases: Drag force up to 77%, inertial force up to 17%, and bending moment up to 16% over 110 years. The wave loads exerted by waves on the monopile are compared to the dynamic response of the monopile, via OpenFAST. An analysis of extreme waves indicates scalable long-term trends across different sea states.

爱尔兰大西洋沿岸近海固定单桩结构波浪荷载的长期演变（1900-2010）

在这项研究中，我们利用ERA20再分析数据中的显著波高和峰值波周期值，并根据哥白尼网站的ERA5进行校准，探索了爱尔兰西部北大西洋圆柱形单桩结构波浪荷载的长期趋势。对固定单桩结构的波浪激励进行了评估，单桩是波浪能转换器和海上风力涡轮机的重要组成部分。基准的5MW国家可再生能源实验室（NREL）固定单桩涡轮机（OC3）用于分析阻力，惯性力和前后力矩，显示出显着的增加：在110年中，阻力高达77%，惯性力高达17%，弯矩高达16%。通过OpenFAST将波浪作用在单桩上的波浪荷载与单桩的动力响应进行了比较。对极端海浪的分析表明，不同海况的长期趋势是可扩展的。
