Summary of Technical Specifications for Offshore Wind Farm Facilities

Abstract

[Introduction] This paper aims to promote the establishment of a complete technical standards system for offshore wind farms. [Method] The problems existing in the construction of offshore wind farms in China were pointed out, the standards for offshore wind farm facilities at home and abroad were summarized, and the exploration and effectiveness of the technical specifications for offshore wind power facilities by China Classification Society(CCS) were introduced. [Result] Despite the rapid development of offshore wind power in China, the supporting technical specifications for offshore wind power facilities have not been followed up in time, and the whole life cycle technical specifications system, including design, construction, installation, operation and maintenance and abandonment, has not been established. Although Europe has a mature specifications system for offshore wind power facilities, it cannot be completely copied and used, such as the LRFD method of structural design which is related to the environmental conditions and reliability index of the sea area, and the partial factor applicable to the European sea area is not applicable to the Chinese sea area. [Conclusion] Therefore, the technical specification system for the domestic offshore wind power facilities requires the joint efforts and cooperation of the industry, traditional ocean engineering specialty should play a greater role in this field, and the research achievements by CCS in this field can provide some reference values for the establishment of the technical specification system.
