Boskalis Changfang Xidao jacket foundations

All Foundations Stand at Changfang & Xidao Wind Farms Offshore Taiwan

All 62 three-legged jacket foundations have been installed at the 589 MW Changfang and Xidao wind farms offshore Taiwan, according to Dennis Sanou, CEO of Changfang Xidao Offshore Wind Farms at Copenhagen Offshore Partners.

Century Wind Power was responsible for manufacturing the jacket foundations, with the last one being built a few days ago.

Boskalis was in charge of installing the units at the offshore construction site, located some 15 kilometres off the coast of Changhua County.

The company deployed its Bokalift 1 and Bokalift 2 crane vessels for this mission. The ships were supported by vessels BOKA Atlantic and BOKA Tiamat which provided essential supporting activities.

Bokalift 1 was assisted by Boskalis’ heavy transport vessel Mighty Servant 3, which transported a number of jackets from the Port of Taipei to the offshore wind farms.


The Dutch company completed the first phase of foundation installation in July of last year. A year later, Boskalis reached the halfway mark on the project by installing 31 jacket foundations.
