Project:  CNOOC GUANLAN

Time of completion:June 2023

Project introduction: As China's first deep-sea floating wind power turbine platform, Guanlan has a capacity of 7.25 MW, an overall height of more than 200m and a total draft weight of 11,000 tons, with the water depth of 120m. The annual power generation of the wind turbine can reach 22 million kilowatt hours. Through the dynamic submarine cable, it can save nearly 10 million cubic meters of natural gas and reduce carbon dioxide emissions by 22,000 tons per year.

Project highlights: Guanlan is China's first floating wind power turbine platform with a working sea area of more than 100km from the coastline and a water depth of more than 100m. It is also the world's first semi-submersible deep-sea wind power turbine platform that supplies power to offshore oil and gas fields and has the worst marine environment, which poses a huge challenge to the platform design. Through technological innovations such as optimizing the platform scale and adding efficient damping structures, the platform capable of resisting the maximum 17-level super typhoon. The tilt angle is only about 10 degrees in extreme environment, and it can ensure the safety of the wind turbine at a wind speed of 84 m/s.
