Haihao Group’s wind power flanges help China’s new offshore wind power projects

As a leader in pipeline systems, Haihao Group plays a key role in promoting new offshore wind energy projects in China. The recently launched Shenergy Hainan CZ2 and China Datang CZ3 offshore wind power projects, with a total investment of approximately RMB 29.6 billion, mark an important step towards the construction of the Hainan Free Trade Port and the promotion of a “clean energy island”.

Wind Power Flange

These two offshore wind power projects are located in the northwest waters of Danzhou City, Hainan Province, with a total planned area of 383 square kilometers. The total installed capacity is 2.4 million kilowatts, including the construction of four 220 kV offshore booster stations and two onshore centralized control centers. It is worth noting that these two projects are the first offshore wind power projects in China to achieve full life cycle intelligent management and ensure “zero carbon” emissions from onshore centralized control centers and offshore booster stations.

Once completed, these two projects will provide Hainan Province with 7.46 billion kilowatt hours of clean electricity every year. This will help adjust the province’s power grid structure and industrial structure, and promote the region to take the lead in decarbonizing the power system.

Large flange for wind power

In these two offshore wind power projects, Haihao Group’s wind power flanges played a key role. Our company will provide some wind power flange products for these two projects. Due to the particularity of its working environment, wind power flanges have some characteristics that other flanges do not have.

1.Challenging work environment:

Manufacturing wind turbine flanges requires precision and meticulousness, often in challenging offshore environments. Haihao Group has abundant raw material suppliers. We can select corrosion-resistant and low-temperature-resistant materials for flange forging according to project needs. With more than 40 years of experience in the field of forged flanges, the wind power flanges forged by our company have won domestic unanimously recognized by external customers.

2.Manufacturing Complexity:

The production of wind turbine flanges involves a complex engineering process as they play a vital role in connecting and supporting the various components of the wind turbine. Haihao Group’s manufacturing facilities are equipped with advanced technology to meet the stringent specifications of offshore wind projects.

3.Commitment to sustainability:

Haihao Group’s wind power flange manufacturing focuses on sustainability. Recognizing the importance of “zero carbon” emissions in offshore wind projects, the manufacturing process emphasizes environmental responsibility, contributing to the overall ecological goals of these projects.

Haihao Group’s participation in the Shenergy Hainan CZ2 and China Datang CZ3 offshore wind power projects demonstrates its determination to promote clean energy solutions. As these projects move toward completion in 2026, Haihao Group’s wind power flanges will continue to play a vital role in driving China’s offshore wind industry towards a sustainable and carbon-neutral future.
