Jan De Nul Group has started offshore installation activities for the TPC Offshore Wind Farm. The first twelve pin piles have been installed and the first export cable has been connected to shore near Fangyuan in Changhua County, on the West Coast of Taiwan.
The TPC Offshore Wind Farm consists of 21 offshore wind turbines on pre-piled jackets, each anchored to the seabed by four steel pin piles. In a first phase, Jan De Nul Group will install 44 pin piles for 11 jackets, of which 12 are installed. Forty more pin piles are shipped from the fabrication yard in South Korea to Taiwan in the coming weeks.
Simultaneously, Jan De Nul’s cable-laying vessel Willem de Vlamingh started with the installation of the submarine export cables. The first out of four cables was successfully pulled to the onshore junction box. Due to the presence of a nearshore oyster farm and an important shipping lane in the trajectory of the subsea cables, these subsea cables must be buried 21 metres below the seabed. Therefore, Jan De Nul Group drilled four 1 km-long pipes by horizontal directional drilling (HDD) from offshore to the onshore junction box. The landfall works were executed by means of two of Jan De Nul’s Starfishes, trenching excavators, and with the support of Taiwan-based Hung Hua Construction.
Taiwan Power Company (TPC) awarded the ‘Offshore Windfarm Phase 1 Project – Demonstration’ contract to the Consortium Jan De Nul-Hitachi on 13 Feb 2018. The project entails the manufacturing and installation of 21 offshore wind turbines, each with a capacity of 5.2MW.
