中文摘要：

随着能源需求的逐步增大，海上风电场建设需要5MW甚至更大功率的海上风力机，固定式基础已经无法满足设计要求．浮式风力机的研究成为新的热点。介绍国际上已建成的2处海上浮式风电机组样机的概况．对比不同浮式基础结构的性能，分析各国模型试验的特点，探讨试验研究的关键技术，提出适合于我国海上浮式风电机组理论和试验研究的建议，为我国未来建设更大规模的海上浮式风电场提供了理论依据.

英文摘要：

With energy demand increasing gradually, offshore wind turbines of 5 MW or bigger are required in offshore wind farms. The fixed foundation structure cannot meet the requirements, and development of the floating offshore wind turbines （FOWTs） becomes the new trend. The general characteristics of two FOWT prototypes were presented. The features of different floating foundations were compared. Performences of model experiments were analyzed and the key technologies involved are investigated. Some suitable suggestions on theoretical and experimental researches of floating wind turbines in China were provided. The theoretical foundation for constructions of large-scale offshore wind farms in China was offered.
