The "Haiyou Guanlan" is located in the offshore oil field waters 136 kilometers away from Wenchang, Hainan, with an installed capacity of 7.25 megawatts. It consists of wind turbines, floating foundations, mooring systems, and dynamic cables. The overall height exceeds 200 meters, and the total draft weight reaches 11000 tons. It is fixed by mooring with 9 anchor chains at a depth of 120 meters in the ocean. The green electricity generated is connected to the offshore oil field cluster power grid through a 5-kilometer long dynamic submarine cable. After production, the average annual power generation will reach 22 million kilowatt hours, all of which will be used for the production of oil fields. It can save nearly 10 million cubic meters of fuel and natural gas annually, reducing carbon dioxide emissions by 22000 tons.

 

 

 

According to Tang Xinguo, Director of Wenchang 13-2 Oilfield at CNOOC Zhanjiang Branch, the "CNOOC Guanlan" is the first floating wind power platform in China to operate in a sea area more than 100 kilometers away from the coastline and with a water depth exceeding 100 meters. In the design and construction of this platform, by studying multi factor joint distributed environmental data, innovative application of integrated design and iterative technology of wind turbines and floating foundations, ensure the safe and stable operation of the "Sea Oil Mission" under the strongest typhoon with a magnitude exceeding 17.

 

 

 

In order to ensure the continuous and stable operation of the power grid of the oilfield group after wind power is connected to the grid, the Wenchang Oilfield Group has created a new integrated power supply model of "wind power+gas power+smart grid". By cooperating with the oilfield energy management system, wind turbine monitoring system, and wind power prediction system, the four fuel power stations in the oilfield cluster are integrated with the "Sea Oil Mission Hills" wind power platform as a whole. The unified control and management of wind power and oilfield power have been achieved, forming a dual guarantee of active control and passive response, thereby ensuring the safety and stability of the oilfield microgrid, promoting the development of offshore wind power as a direct power supply technology for offshore oil and gas grids, and providing a "offshore oil model" for the management and on-site consumption of offshore wind power energy.

 

 

 

According to Qin Lifeng, the production department manager of CNOOC Zhanjiang Branch, the Wenchang Oilfield Group Power Grid is an effective attempt by CNOOC to create a green and low-carbon new offshore power system. On the one hand, the high stability demand for offshore oil and gas power has been achieved through the power networking of multiple oil fields; On the other hand, by connecting to large capacity renewable energy power generation units, a crucial step has been taken for the high proportion of new energy electricity utilization in future offshore oil and gas fields.

 

 

 

China is rich in far-reaching sea wind energy resources. According to the data from the National Climate Center, the technical exploitable amount of China's far-reaching sea wind resources exceeds 2 billion kilowatts, with huge potential. The development and application of offshore wind power resources is one of the most effective ways to achieve China's carbon peak carbon neutrality goal.

 

 

 

Yang Yun, Executive Vice President and General Manager of the New Energy Department of CNOOC, expressed the hope that through the implementation of the "CNOOC Mission Hills", China's far-reaching offshore floating wind power will achieve substantive breakthroughs in core technology, large-scale offshore installation equipment, and industrial chain resource integration, achieve stable operation of high proportion renewable energy in microgrids, and create a new model for the integrated development of offshore wind power and offshore oil and gas. Ultimately, by building offshore zero carbon oil and gas fields, we will achieve green and low-carbon development of marine oil and gas, and promote the organic integration of traditional oil and gas with new energy.
