Aarsleff Nets Nissum Bredning Deal

Aarsleff has been awarded a contract for the 28MW Nissum Bredning project in Denmark, where Siemens will test a variety of its new offshore wind solutions.

The Danish contractor will build concrete transition pieces and install the new gravity jacket foundations at the site off Rønland in Denmark, a spokesperson from Siemens confirmed to Offshore WIND today.

At the beginning of this month, Spanish joint venture Navantia-Windar informed it will supply the three-legged jacket foundations and accompanying piles for the project.

Siemens is using piles at the Nissum Bredning offshore wind farm due to seabed conditions that did not allow the use of suction buckets. The company plans to deploy the gravity jacket foundations anchored to the ground with suction buckets on future projects in deeper waters.

The commercial aspect of the offshore wind technology to be tested within the project is expected to show a significant positive impact on the Levelized Cost of Electricity (LCoE), according to Siemens.

Along with the new foundations, the company will install four of its 7MW direct drive wind turbines, as well as a new 66kV voltage solution including a new transformer, cable and switchgear systems, and further innovations regarding tower and controller settings.

Navantia-Windar will deliver the last Nissum Bredning jackets by mid-2017, with the turbine installation scheduled for summer 2017 and commissioning expected to take place in the third quarter of next year.
