DONG Picks Steelwind to Build 36 Borkum Riffgrund 2 Foundations

DONG Energy has awarded Germany’s Steelwind Nordenham with a contract to manufacture 36 monopiles and transition pieces for the 450MW Borkum Riffgrund 2 offshore wind farm.

This is not the first time Steelwind Nordenham was contracted by DONG to build foundations for an offshore wind project, but it is the first time the company will produce transition pieces for the Danish offshore wind developer. The two companies previously collaborated on foundations for the Race Bank offshore wind farm in the UK.

Once manufactured and delivered in early 2018, the foundations and the transition pieces will be installed by Jan De Nul’s vessel Vole au vent some 54km off the coast of Lower Saxony, next to Borkum Riffgrund 1.

They will support 36 out of the wind farm’s 56 MHI Vestas V164-8.0MW wind turbines. The remaining 20 turbines will be installed on jacket foundations.

Borkum Riffgrund 2 is DONG’s fourth offshore wind farm in German waters. The company decided to build the wind farm in June 2016.

The wind farm is expected to be fully commissioned in the first half of 2019

DONG Energy is the sole owner of Borkum Riffgrund 2, but intends to divest up to 50% of the project at a later stage.
