Total concept for the DanTysk OSS offshore platform

Hollandia Strukton Jointventure

The DanTysk offshore wind farm, situated west of the island of Sylt and directly on the German-Danish border, will be one of the first large-scale offshore wind farms ever to be built in the German North Sea. Completion of the DanTysk wind farm will see the two energy companies behind the project, Vattenfall and Stadtwerke München, playing a key role in Germany's energy transition policy. With a total of 80 wind turbines, DanTysk will soon be able to provide up to 400,000 homes with green energy.
The substation is the heart of the wind farm. This is where the electricity generated by all of the wind turbines is collected and converted to a higher voltage.

It essentially consists of two parts: the topside, where all the technological devices are housed, and the jacket, a steel construction which stands on the bed of the North Sea and reaches a height of approximately 45 metres.


The project organisation was located on the grounds of Holllandia in Krimpen aan den IJssel. Here are the so-called topside and the jacket build. Hollandia Strukton has found the right partner in ERIKS for the support in the engineering process and the integration of the various systems. The platform is 75 km from the coast, where the challenge is that the platform must be automatically operated. This requires a reliable system that can be fully operated and analysed from the mainland. During the construction there was a very intensive contact between all disciplines of the project organisation on the one side and ERIKS on the other side.

ERIKS' added value to this project are:
  • Support engineering/ project organisation;
  • Fully remote controlled Fail Safe shut-off valve systems;
  • Process control (pressure, temperature, level, flow) with communications, according to HEART;
  • Protocol;
  • Flowmeters for fuel- and watersystems;
  • Tank measuring system;
  • Tank security; overfill protection; flame returning establishments;
  • All fittings;
  • Commissioning;
  • Final documents.
