Reviews and comments on the design for offshore wind structures

Based on the state-of-the-art and trends of the offshore wind farm development as well as the problems in the design and R&D for the offshore wind structure in domestic offshore industry,some key aspects such as concept,method and criterion for the design of offshore wind structures are discussed.The traits of the structure,load and serving of offshore wind structures are analyzed.The differences in the design of offshore wind structures from those of hydraulic structures and offshore oil & gas structures are emphasized.Furthermore,which of the two standards of DNV-OS-J101 and API RP 2A that should be referred to for the design of offshore wind structures is recommended based on the differences between offshore wind power industry and offshore oil & gas industry,and then the traits,loads and reference standards for the design of offshore wind structures are presented.Finally,the offshore wind structures suitable for domestic coastal conditions and their design problems are proposed.Some problems which should be paid more attention to and have to be avoided in developing offshore wind farms are highlighted.
