Jan De Nul has completed the installation of two high-voltage submarine export cables for the Fengmiao I offshore wind farm, located off Taichung, Taiwan.
The two cables, measuring 45,000 m and 44,000 m, have a combined weight exceeding 8,000 tonnes. Following installation, they have been positioned and left on the seabed until the offshore substation becomes available, allowing progress on the project’s electrical infrastructure while other offshore works continue.
These export cables will play a key role in transmitting electricity generated offshore to the onshore grid, supporting the integration of Fengmiao I’s output into Taiwan’s power system.
The Fengmiao I offshore wind farm is designed with a capacity of 500 MW, sufficient to supply nearly 500,000 homes. It forms part of a broader Fengmiao development targeting a total capacity of 1,800 MW in Taiwanese waters.
The next phase of the project involves seabed burial of the installed cables. Jan De Nul will carry out this work using its PT 1 trencher, a process aimed at protecting the subsea infrastructure and ensuring long-term operational stability.
Once the offshore substation is ready, the installed cables will be connected to complete the electrical system and enable integration with Taiwan’s grid and associated onshore infrastructure.
For transport, installation, and protection activities, Jan De Nul deployed its cable-laying vessel Willem de Vlamingh, designed for complex subsea cable operations and capable of supporting multiple installation phases.
The project site is located approximately 35,000 m offshore Taichung. With the completion of this installation stage, Fengmiao I advances toward full grid connection and contributes to Taiwan’s offshore wind expansion.
