The very first jacket foundations have been installed in Taiwanese waters, approximately 10km off the coast of Fangyuan in Changhua County.
In total, the TPC Offshore Wind Farm will comprise 21 offshore wind turbines, each installed on a jacket foundation, which are anchored to the seabed by four steel pin piles. Installation of these pin piles started in June this year. After installing the jackets on the pin piles, the void between these two is grouted to create a firm connection.
All 21 jackets have been manufactured at the South Korean Shipyard Company Samkang, and measure between 55 m and 62 m in overall height. Five trips are needed for the two chartered heavy transport vessels to bring all jackets from South Korea to Taiwan.
The jackets include a 7.2 m high Transition Piece (TP) with a diameter of 5.4 m to support the towers carrying the Hitachi 5.2 MW turbines. Each jacket comes with two davit cranes for cargo hoisting and two boat landings to enable personnel access. The jackets are equipped with specialized offshore accessories such as navigation lights, foghorns and CCTV cameras.
