Fulan Offshore Engineering announced that its CLB Ai Lan Yi Hao (AL-1) has completed installation of the first 500kV export cable circuit for the Yangjiang Fanshi-1 Offshore Windfarm Development Project in Guangdong, China. The project consists of two 500kV circuits connecting the offshore substation and the interim compensation station, with each circuit measuring about 80 km, a length that surpasses previous industry records for 500kV AC subsea cables.

The company noted that this installation represents its first completed 500kV HVAC subsea cable operation. The second circuit has been loaded onto a cable-lay vessel equipped with a DP2 system to handle expected winter weather, and the project aims to achieve commissioning before the end of 2025.

According to Fulan Offshore, the continued development and wider use of 500kV subsea cable technology reflects its growing presence in the China domestic offshore wind sector.
