General design and key technologies of"CNOOC Guanlan"floating wind turbine platform
The"CNOOC Guanlan"is the world's first semi-submersible floating wind turbine platform in the deep & far sea to supply power to surrounding oilfields.The platform design faces a series of challenges in terms of new technologies and fields,such as harsh sea conditions in the South China Sea,high average cost of electricity generation per kilowatt hour,and stability of integrated development and transmission of offshore wind power and oil and gas fields.To address these issues and challenges,the general design of the"CNOOC Guanlan"was proposed.Key technologies included the development of a triangular four-column typhoon-resistant floating foundation,analysis and design methods of efficient quasi-coupling of floating wind power system,efficient structural fatigue analysis method,simple mooring system design,and control of floating wind power connected to offshore oilfield island microgrid.Based on the above technologies,the world's first new small-waterline triangular four-column semi-submersible floating wind turbine platform suitable for harsh sea conditions was developed to realize the integrated development of floating wind power and offshore oilfields.The completion and operation of this platform marks a key step forward in the development of floating wind turbines in deep & far seas in China,providing a reference for the development of similar floating wind turbine platforms in deep &far seas and their integration with other industries.
