Van Oord Installs All Walney Extension Foundations

Dutch offshore construction specialist Van Oord has installed all 87 foundations at DONG Energy’s 659MW Walney Extension wind farm in the Irish Sea.

“All monopile foundations and transition pieces are now in place for both Walney Extension 03 & Walney Extension 04. Installation works are progressing as planned and we are working towards our next milestone of first power generation from the site,” DONG Energy told Offshore WIND.

The wind farm will consist of 40 8.25MW MHI Vestas and 47 7MW Siemens wind turbines.

Seajacks’ wind farm installation vessel, Seajacks Scylla, arrived to the Belfast Harbour in early August to load the MHI Vestas turbine components and install them some 19 kilometres off the Cumbrian coast.

The turbine components are being stored in Belfast and the construction is coordinated from the port of Barrow in Furness.

Following the installation of the 40 MHI Vestas turbines on Walney 3, Seajacks Scylla will install the 47 Siemens turbines on Walney 4.

Once fully commissioned in 2019, Walney Extension will become the world’s largest operating offshore wind farm.
