Abstract: :The evaluation of local wind resources is very important in earlier wind investment stage.Installation of offshore wind farm needs lo ts of offshore engineering mechanical equipments such as vessel, floating crane, etc.The offshore construction is greatly limited and costly.Comparing various anemometer towers worldwide, the advantages and disadvantages of various anemometer towers are analyzed and the adaptable structure and foundation of anemometer tower is proposed.It could be a theoretical guidance for offshore wind power development.
