Abstract:From the aspects of the offshore wind turbine installation technology, wind turbine installation vessel type and research status of key technology, the current situation and the latest development of offshore wind turbine installation vessel technology are introduced. In response to the continuous expansion of offshore wind turbine projects into deep and open seas, the self-propelled jack-up wind turbine installation vessel with multi-function concentration, strong carrying capacity, high stability, high positioning accuracy and environment-friendly will be rapidly developed.
