The floating wind power platform “CNOOC Mission Hills”, built by CNOOC, was successfully towed and set sail under the guarantee of the Qingdao Maritime Safety Administration, sailing from Qingdao to Zhuhai, with a journey of nearly 1420 nautical miles and a voyage time of about 15 days.

It is reported that the “CNOOC Mission Hills” platform is composed of three side columns and one center column. The side length is more than 80 meters, the height is about 35 meters, and the weight is nearly 4000 tons. The fan will be installed on the center column. The platform will be installed in the offshore oil field area 136 kilometers away from Wenchang, Hainan. The sea area has high winds and waves. It is the world’s first “double hundred” offshore wind power project with water depth of more than 100 meters and offshore distance of more than 100 kilometers. After the project is put into operation, the power generated by the wind turbine is connected to the power grid of the offshore oil field group through dynamic submarine cables for oil and gas production. The annual power generation can reach 22 million kWh, which can save 7.73 million cubic meters of fuel gas and reduce 22000 tons of carbon dioxide emissions.

Due to the severe limitation of the handling ability of the tugboat group, in order to ensure the safety of the navigation of the platform, Qingdao Maritime Safety Administration worked out the towing plan with CNOOC in advance, issued the navigation warning in both Chinese and English, and selected the law enforcement backbone to carry out on-site inspection on the two tugboats to ensure that the ship is towing and seaworthy, and the crew is competent. During towing, separate monitoring window shall be opened, VTS and AIS shall be fully used to monitor the whole process of the ship, and safety warning information shall be released in time. At the same time, the Qingdao Maritime Safety Administration dispatched the “Haixun 05709” wheelset platform to escort the whole process of undocking, ballasting and towing operations, drive away the fishing boats that hinder navigation, maintain the navigation order, and ensure the towing safety and the navigation safety of the jurisdiction.
