The next step is the installation of the 16 three-legged jacket foundations which would complete the 2021 foundation installation campaign at the site, Boskalis said.

The remaining 138 pin piles and 46 jacket foundations are scheduled to be installed in 2022.

Boskalis is responsible for the transportation and installation of the wind farm’s 62 jacket foundations and the 186 accompanying pin piles. The Dutch company is carrying out the work in a joint venture with Taiwan’s Hwa Chi Construction Co.
