The Hai Long Offshore Wind Project joint venture (Northland Power, Yushan Energy, Mitsui & Co., and Gentari) announced the official start of offshore construction on 11 April.

The first campaigns will involve the installation of foundation pin piles, followed by the laying of subsea cables and the installation of offshore substations. Wind turbine installation activities are expected to start next year.

According to a social media update posted on 12 April by the vessel owner, CSBC-DEME Wind Engineering (CDWE), Green Jade has installed pin piles at five locations so far.

For the work at the offshore wind project site off the coast of Changhua, the 2023-built vessel is using a subsea self-levelling pre-piling template.

“The template was engineered and built by CDWE, which features state of the art tools to ensure the accurate placement of the piles within stringent tolerances in the highly demanding conditions of the Taiwan strait,” CDWE said.

Green Jade, the first offshore heavy lift DP3 installation vessel built in Taiwan, will also install 73 wind turbine foundations and two foundations for the wind farm’s offshore substations, and will be deployed on the Hai Long project until 2026.

The 1,022 MW Hai Long project comprises two offshore wind farms, the 518 MW Hai Long 2 and the 504 MW Hai Long 3 and is being developed in three phases. Hai Long 2 is further split into two smaller offshore wind farms, the 294 MW Hai Long 2a and the 224 MW Hai Long 2b.

The wind farm’s Siemens Gamesa SG 14-222 DD wind turbines will be installed on three-legged jacket foundations which, for Hai Long 2b and Hai Long 3 are being manufactured by Samkang M&T and for Hai Long 2a by Century Iron & Steel Industrial (CIS) and Century Wind Power (CWP).

The pin piles for the Hai Long 2a part of the project are being delivered by CSBC while EEW is delivering 156 pin piles for Hai Long 2b and Hai Long 3.
