The Offshore Wind Farm, MERKUR Offshore is located in the German Exclusive Economic Zone (EEZ) in the North Sea, approximately 45 km north of Borkum Island in the north-eastern part of the specified zone for offshore wind farms. The project site covers an area of 47 km² in total.
Merkur Offshore will be equipped with 66 wind energy converters of GE’s offshore wind turbine “Haliade 150” with nominal power of 6 MW each. The hub height of a single turbine is more than 100 m above water level and the innovative gearless 6 MW machine is equipped with one of the largest rotors in the wind industry covering an area equivalent to three football fields with its diameter of 150 m.

Story

Merkur Offshore GmbH is a joint venture between its shareholders Partners Group, InfraRed Capital Partners, DEME Concessions and Coriolis focusing on the construction and operation of the Merkur Offshore Wind Farm.
Our mission is to support the creation of clean and sustainable energy. We are currently building 66 GE Haliade 6MW turbines allowing approximately 500,000 households to be supplied with green energy.

During construction and operation our highest priority is the health and safety of all project members. We live by our credo: Stop, Review, Plan, then Do!

With the same meticulous care, we protect the environment at all work levels and at any phase of the project.

The project management team, located in Hamburg, Germany, is directly embedded in the company. It coordinates the interfaces between the key contractors GeoSea NV (for the Balance of Plant scope) and GE Renewables (as Turbine supplier), the grid operator TenneT and the public authorities.
