Van Oord has completed the installation of scour protection and the transport and installation of the 87 foundations for the Walney Extension offshore wind farm. When operational late in 2018, the world’s largest offshore wind farm will be capable of supplying renewable energy to more than half a million households in the United Kingdom. It will contribute to governmental targets to ensure that 15% of the UK’s energy is being produced sustainably by 2020. Offshore installation vessel Aeolus and heavy lift installation vessel Svanen played important roles in the efficient construction of the offshore wind farm.
Logistical and technical challenges
After the successful completion of Burbo Bank Extension offshore wind project in 2016, Van Oord again reached agreement with DONG Energy to build a new offshore wind farm. The project had both logistical and technical challenges. Simply transporting the foundation elements to Belfast from various locations spread across Europe was a logistical puzzle in itself. The monopiles were installed safely by our top duo Svanen and Aeolus well within the tight time schedule. In addition to the traditional method of installing foundations with the Aeolus jacked (standing on legs), the installation vessel accomplished a new first by installing the transition pieces while floating.
