The 1,022 MW Hai Long comprises two offshore wind farms, the 532 MW Hai Long 2 and the 512 MW Hai Long 3 and is being developed in three phases as Hai Long 2 is further split into two smaller offshore wind farms, the 300 MW Hai Long 2a and the 232 MW Hai Long 2b.
The offshore wind project will feature 73 Siemens Gamesa SG 14-222 DD wind turbines , installed on three-legged jacket foundations and two substations.
Last weekend, the first substation was installed at the site approximately 45-70 kilometres off the Changhua coast by CDWE’s Green Jade , according to a social media update posted on 20 May by the company.
Measuring 52 metres in length, 38 metres in width, and 32 metres in height, the OSS topside sits on a four-legged jacket foundation installed at the beginning of May.
A consortium comprising Semco Maritime and PTSC Mechanical & Construction (PTSC M&C) is responsible for delivering the two offshore substations for the 1,022 MW Hai Long offshore wind project.

The first steel for the approximately 2,800-tonne structure was cut in November 2022. That same month, CDWE signed a contract for the transportation and installation of the foundations, turbines, and offshore substations for the two offshore wind farms making up the project.
Green Jade will be deployed on the Hai Long offshore wind farm until 2026.
The substations will be equipped with two Palfinger’s stiff boom cranes with an outreach of 26 metres, four life raft davits, and four fixed boom cranes, with the latter to be used to lift materials and tools from a crew transfer vessel (CTV) onto the offshore substation.
Expected to be commissioned in 2025/2026, Hai Long is owned and developed by Hai Long Offshore Wind, a consortium comprising Northland Power, Yushan Energy, Mitsui & Co., Ltd., and Gentari.
