The construction of the offshore substation that will be installed at the Greater Changhua 2b and 4 wind farm sites commenced in 2023 at Seatrium‘s Pioneer yard in Singapore.

The jacket foundation that will hold the 3,260-tonne topside has already arrived in Taiwan, according to Jayaram Naidu, Vice President and Managing Director of Greater Changhua.

“We impressively completed the structural work of the 3,260-ton topside and the 3,137-ton OSS jacket foundations in just 212 days, setting a new Ørsted record. Most importantly, our unwavering commitment to safety ensured everyone returned home safely, achieving 2.8 million man-hours of ZERO lost time injuries (LTI),” said Naidu.

Wind Farm Update

In May 2023, Petrovietnam Technical Services Corporation (PTSC) signed a contract with Ørsted to supply 33 foundations for the 920 MW offshore wind farms. Additionally, HSG Sungdong in South Korea is responsible for delivering another 33 units for Greater Changhua 2b and 4.

The onshore substation will be built by Taiwan Cogeneration Corporation (TCC) under a contract signed with the developer in 2023.

Located 35-60 kilometres off the coast of Changhua County, the offshore wind farms commenced construction in March 2023, following Ørsted’s final investment decision on the 920 MW projects.
