Taiwan, Changhua County: Belgium-based offshore installation contractor Jan De Nul has upgraded the onshore substation in Changhua County.
This was essential for the connection of the first state-owned wind farm ‘Taiwan Power Company Offshore Windfarm Phase 1 Project – Demonstration’ to the Taiwanese power grid.
Together with its Taiwanese subcontractor Chung-Hsien Chen, Jan De Nul Group completed the installation and commissioning of new electrical equipment, including high voltage transformers, high-voltage and medium-voltage switchgear, a new SCADA control room and emergency power supply, inside the onshore substation in Dacheng. This upgrade was essential for the substation to be able to receive power generated by the new offshore wind farm.
The company has also completed the installation of four medium-voltage export cables connecting the TPC Changhua offshore wind farm to the shore in Taiwan.
Jan De Nul’s cable-laying vessel Willem de Vlamingh successfully installed the four subsea export cables from the offshore wind farm site, 10 km off the coast, to the shore where they were connected at the landfall area near Fangyuan.
After passing a 24-hour energisation test, the upgraded substation was successfully connected to the national grid for the first time in this new configuration, Jan De Nul said.
The turbine installation campaign, due to start in August, will feature Jan De Nul’s offshore jack-up installation vessel Taillevent.
The ‘Taiwan Power Company Offshore Windfarm Phase 1 Project – Demonstration’ was awarded to the Consortium Jan De Nul–Hitachi in February 2018.
Jan De Nul Group is responsible for the full balance of plant, including design, fabrication and installation of the foundations, and the provision of the offshore vessel for the installation of the wind turbines. Also included is significant electrical scope, including the supply and installation of the cables both onshore and offshore, as well as upgrading an electrical substation.
Hitachi Ltd. is in charge of manufacturing, assembly, installation and other works related to the 21 Typhoon certified offshore wind turbines using a downwind rotor, each with a capacity of 5.2 MW.
