海上可移动式风机装备研制过程中的关键技术问题

Key technical problems in the development ofmobile floating offshore wind turbine

可移动式风机是一种既能利用海上风资源进行发电储能,又具备一定自航能力的海上能源装备。与固定式海上风机以及系泊式漂浮风机相比,可移动式风机的有效作业水深更大,可以开发深远海蕴含的大部分风能,同时还可以为远海生产生活设施进行供电。本文基于国内外相关最新研究资料,结合作者自身的理解和探索,从基础选型、概念可行性论证、一体化动力分析技术、作业决策技术、安全性评估、水池模型试验技术、建造及安装技术等多个方面,对研制可移动式风机过程中需要解决的关键技术问题进行探讨。

Mobile floating offshore wind turbines(MFOWTs)can store the generated wind energy onboard,and navigate to preset working areas due to their mobility.Compared to fixed and moored floating offshore wind turbines,MFOWT can not only harness the abundant far-offshore wind resource but also supply power to offshore energy consumers,because of its superior working ability in deep sea.In this paper,key technical problems in the development of MFOWT are summarized and discussed in several aspects based on a litera⁃ture review and our research:(1)floating substructure selection;(2)conceptual design and approval;(3)dy⁃namic response analysis for the integrated system;(4)operational strategy decision;(5)safety assessment;(6)model test in ocean wave basin;(7)construction and installation.
