虽然北海的近海气候为开发可靠和强大的风能提供了巨大的潜力，但它对海上风力发电场的建设者提出了挑战。使用大型重型自升式船（HLJV）将风能转换器的组件运输到海上地点。经过预压和顶升程序后，需要进行重达950吨的三脚架基础的海底提升，以及大高度的塔和机舱安装。由于典型的海上风力发电场由80个或更多独立的风力涡轮机组成，安装工作通常在整个冬季以串行方式进行。因此，许多关键的海上作业都是在每日或每周天气报告的基础上连续进行的。这些作业不能依赖于最佳的天气条件，因此规划和工程必须考虑到适当的风浪条件，同时考虑到天气窗口可靠性和土壤条件的不确定性。本文展示了如何将从数值耐波性和结构模拟中得出的天气标准纳入涵盖90个独立系列装置的项目模拟模型。基于后播再分析，在多季节天气情景下进行了装置模拟。这使得量化特定海洋扩散及其相关安装过程的适用性成为可能。导出了与天气有关的延误的风险概况。ASME版权所有©2014
While the offshore climate in the North Sea bears a great potential for the exploitation of reliable and powerful wind energy it poses a challenge for the constructors of offshore wind farms. Large heavy lift jack-up vessels (HLJV) are employed to transport the components of the wind energy converters to the offshore location. After a preloading and jacking procedure, subsea lifts of tripod foundations weighing up to 950tons as well as tower and nacelle installations at large heights need to be undertaken. As typical offshore wind farms consist of 80 or more separate wind turbines the installation works are conducted in a serial manner — often through the winter season. Thus, many critical offshore operations are conducted consecutively on the basis of daily or weekly weather reports. These operations cannot rely on optimal weather conditions therefore planning and engineering has to cover appropriate wind and wave conditions taking into account contingencies for uncertainties in the reliability of weather windows as well as in the soil conditions.This paper shows how the weather criteria derived from numerical seakeeping and structural simulations are taken into a project simulation model covering 90 separate serial installations. Based on hindcast re-analyses installation simulations are conducted in multi-seasonal weather scenarios. This enables the quantification of the suitability of a particular marine spread and its associated installation processes in combination. The risk profile of weather related delays are derived.Copyright © 2014 by ASME
