The company Baltic Eagle GmbH has contracted Heerema Marine Contractors for the transport and installation of the Offshore Substation (OSS) for the Baltic Eagle offshore wind farm in the Baltic Sea.

The Baltic Eagle wind farm is located 30 kilometers to the northeast of Rügen island off the coast of Pomerania (Germany), and this new 476 MW installation will supply renewable energy to 475,000 households. The Baltic Sea holds an incredible potential of 93,000 MW for offshore wind in Europe. Alongside Germany, several countries, such as Poland, Sweden and Estonia are exploring new opportunities for offshore wind developments.

Baltic Eagle represents the second large offshore initiative promoted by the Iberdrola group in Germany, after the commissioning of the Wikinger offshore wind farm (350 MW) at the end of 2017. The company also has another offshore installation currently in development in Germany: Wikinger Süd (10 MW). These three wind farms, located next to the island of Rügen, will give rise to the largest offshore wind complex in the Baltic Sea, with a total installed capacity of 836 MW and a joint investment of €2.5 billion

The offshore substation for the Baltic Eagle has the primary function to collect the electricity produced by the 50 9.53-MW wind turbines in the field and transform the voltage from 66 kV to 220 kV. The OSS consists of a substructure, foundation piles, and a topside weighing a total of 7,150 metric tons.

After the successful installation of two major offshore substations using MasterFlow 9800 in Asia last year, Heerema has awarded Master Builders Solutions a supply contract for the Baltic Eagle offshore structural grouting scope. Heerema and Master Builders Solutions intend to collaborate across regions in the future to lever their respective offshore competencies.
