Abstract Simplified design procedures for offshore wind turbine (OWT) support structures are necessary in the concept and tender design stages for assessing the financial viability. Building upon the previous research on simplified monopile design, this paper presents a similar method to design jacket supported OWTs founded on piles or suction caissons. The method is based on the minimum and necessary data, namely the site characteristics (wind speed at reference height, wind turbulence intensity, water depth, wave height and wave period), turbine characteristics (rated power, rated wind speed, rotor diameter, cut-in and cut-out speed, mass of the rotor-nacelle-assembly) and ground profile (soil stiffness variation with depth and soil strength). A flowchart of the design process is also presented for visualisation of the rather complex multi-disciplinary analysis. Insights are given for 3 and 4 legged jackets. The calculation procedures that are required can be easily carried out either through a series of spreadsheets or simple hand calculations. An example problem emulating the design of a jacket on piles is taken from literature to demonstrate the proposed calculation procedure. The data used for the calculations are obtained from publicly available sources and the example shows that the simplified method arrives at a similar foundation to the one reported.

海上风力发电机导管架基础的10个步骤概念设计

摘要 海上风力涡轮机 (OWT) 支撑结构的简化设计程序在概念和招标设计阶段是必要的，以评估财务可行性。基于之前对简化单桩设计的研究，本文提出了一种类似的方法来设计基于桩或吸力沉箱的导管架支撑 OWT。该方法基于最少必要的数据，即场地特性（参考高度风速、风湍流强度、水深、波高和波浪周期）、涡轮机特性（额定功率、额定风速、转子直径、切割- 切入和切出速度、转子-机舱-组件的质量）和地面剖面（土壤刚度随深度和土壤强度的变化）。还提供了设计过程的流程图，用于可视化相当复杂的多学科分析。提供了有关 3 和 4 腿夹克的见解。所需的计算程序可以通过一系列电子表格或简单的手工计算轻松执行。模拟桩上导管架设计的示例问题取自文献，以演示所提出的计算程序。用于计算的数据是从公开来源获得的，示例表明简化方法达到了与报告方法相似的基础。模拟桩上导管架设计的示例问题取自文献，以演示所提出的计算程序。用于计算的数据是从公开来源获得的，示例表明简化方法与报告的方法具有相似的基础。模拟桩上导管架设计的示例问题取自文献，以演示所提出的计算程序。用于计算的数据是从公开来源获得的，示例表明简化方法达到了与报告方法相似的基础。
