8.2 Consulting AG assigned for commissioning and completion quality surveillance of the world's largest offshore wind farm on behalf of Vattenfall

Ten months after the start of serial production of the newly developed SG 11.0-200 DD wind turbine from the manufacturer Siemens Gamesa Renewable Energy in Cuxhaven, the offshore project "Hollandse Kust Zuid" is entering the next phase. From May 2022, the installation and commissioning of 140 wind turbines will start 18 to 36 kilometers off the Dutch coast, where 8.2 Consulting AG will carry out quality surveillance activities for commissioning and completion activities of the new turbines.

The inspectors from 8.2 Consulting AG are currently undertaking quality surveillance of the serial production of the nacelles in Cuxhaven, Germany. In parallel the prefabrication of the first 4 turbines was accompanied and supported for more than 12 months in Brande (Denmark) with the existing expertise of 8.2 Consulting AG. The goal was and is always to deliver the highest quality and profitable operation possible in the offshore wind farm "Hollandse Kust Zuid" (HKZ).

With the follow-up order, which was closed on April 4th, 2022, the team will also go out into the construction field from May of this year. The inspectors will travel on a CTV (crew transfer vessel) via the base port of IJmuiden (Netherlands) into the world's largest offshore wind farm to date. Two inspectors from 8.2 Consulting AG will be permanently on site for a period of 12 months to represent Vattenfall.

“After the prototype nacelles in Denmark and the serial nacelles in Germany, the surveillance of commissioning and completion is already the third package at the HKZ wind farm. We as a team are very grateful for this confidence shown by Vattenfall. We look forward continuing to contribute to the success of the project through our efforts.” Michael Renner, project manager at 8.2 Consulting AG.

“8.2 have been a great asset for Vattenfall during the construction of the wind turbines at Brande, Denmark and Cuxhaven, Germany, allowing us to have insight into the quality output in production and to ensure Vattenfall’s interests are well represented. 8.2 were chosen based off their extensive knowledge of the Siemens Gamesa direct drive platform along with the team who have already worked on the SG 11-200 DD, as well as their current performance on the HKZ project. I look forward to the continued collaboration with 8.2 as we move into commissioning and completion of the WTGs on the HKZ Windfarm.” Ben Flett, WTG Engineer, Vattenfall.

Preparations are in full swing for commissioning and completion works to begin at the end of May 2022. By late summer 2023, all 140 wind turbines should be properly commissioned and generate clean electricity for the future owners Vattenfall, Allianz and BASF.
