All 47 wind turbine foundations and subsea cable installation works have been completed at the 376MW Formosa 2 offshore wind farm.
The project is being jointly developed by JERA (49%), Macquarie’s Green Investment Group (26%) and Swancor Renewable Energy (25%).
The final jacket foundation was installed on 26 August, with the subsea cable works reaching installation completion six days later on 1 September.
Since the last construction updates announced in July, Formosa 2 has continued to makesteady progress with all the available weather windows utilised.
Currently Formosa 2 has completed the 27th wind turbine installation, which marks more than half of the total turbines installed.
Among them, eight wind turbines started generating power to the national grid.
The turbine foundations of Formosa 2 were designed and constructed specifically to suit prevailing Formosa 2 site geological and met-ocean conditions off the coast of Taiwan, also taking into account the seismic conditions.
The jacket foundation structures are amongst the tallest constructed to-date world-wide at up to 91m in height and weighing up to 1,581 tonnes.
The 47 structures were installed on the offshore site between April and 26 August 2022.
The pin piles, which the jacket foundations are installed upon, are approximately 2.4 metres diameter, up to 277 tonnes in weight and some 78.9 min length.
The installation of the 188 pin piles was concluded earlier in August 2022.
The wind turbine foundations are connected by 47 sections of Inter Array Cables with a further four export cables transmitting the power to the onshore electricity grid.
The combined total length of installed subsea cables is 114km with all subsea cables rated at 69kV.
Michael Klingele, project director of Formosa 2, said: “We are truly grateful for the efforts of the project team and the support from our partners which were critical in reaching this significant milestone.
“It demonstrates Formosa 2’s dedication and commitment to promoting and realising Taiwan’s green energy transition.”
