Wedoany.com Report-Oct. 30, Fulan Offshore Engineering announced the completion of the first circuit installation of the 500 kV export cable for the Yangjiang Fanshi 1 offshore wind farm, located in Yangjiang City, Guangdong Province. The work was carried out by the company’s cable-laying barge Ai Lan Yi Hao (AL-1).

The 1,176 MW Yangjiang Fanshi 1 offshore wind project is developed by CGN Wind Energy and features two circuits of 500 kV export cables connecting the offshore substation and the interim compensation station. Each circuit extends approximately 80 kilometers. According to Fulan Offshore’s statement on social media, this achievement sets a new industry record for the longest 500 kV AC subsea cable, establishing a benchmark for deep-water offshore wind development in China’s domestic market.

Fulan Offshore highlighted that this marks the company’s first successful installation of a 500 kV high-voltage alternating current (HVAC) subsea cable, representing an important technical milestone. The completion of the first export cable demonstrates the company’s capability in large-scale subsea installation and enhances its competitiveness in high-voltage offshore projects.

The company further noted that the second circuit of the export cable has already been loaded onto another cable-laying vessel equipped with a more advanced DP2 dynamic positioning system, which is designed to operate under the challenging winter sea conditions. Fulan Offshore stated on October 29 that the project remains on schedule, with the goal of achieving commissioning before the end of 2025.

The Yangjiang Fanshi 1 offshore wind farm is located in the South China Sea, near Nanpeng Island, Yangjiang City. Once completed, the project will contribute significantly to the region’s renewable energy capacity and support Guangdong’s offshore wind development strategy.

In parallel, CGN Wind Energy is also advancing the Yangjiang Fanshi 2 offshore wind project, a 1 GW facility situated adjacent to Fanshi 1. For this second phase, ZTT has recently delivered the first batch of 500 kV three-core AC subsea cables, which will be used for power transmission between offshore and onshore substations.

Offshore construction for the Yangjiang Fanshi 2 project is scheduled to commence in 2025, with commercial operation expected to begin in 2029. The two projects together form one of China’s largest offshore wind power clusters, showcasing the nation’s progress in developing high-capacity, deep-water wind farms.

Through these milestones, Fulan Offshore Engineering and CGN Wind Energy continue to advance China’s offshore renewable energy sector, improving technical standards and expanding the application of high-voltage subsea cable systems in deep-water environments. The successful completion of the first 500 kV cable circuit installation at Yangjiang Fanshi 1 marks a step forward in achieving greater efficiency, reliability, and scale in the country’s offshore wind power development.
