Dedicated experts in offshore engineering WINDPOWER Borkum Riffgrund 1 offshore wind farm Customer: Bladt Industries A/S DONG Energy (end client) The project The Borkum Riffgrund 1 Offshore Wind Farm is a wind power project. The wind farm and substation includes 78 wind turbines with a total capacity of 312MW situated approx 38km north of the island Borkum off Germany’s North Sea coast. Borkum Riffgrund 1 will be producing green electricity for around 320,000 German households every year. The offshore substation (OSS) is the heart of every offshore wind farm. Here the energy of the wind turbine generators is bundled and passed on. The substation is also the largest component of the wind farm. With an area of 465 m² it is as big as a multi-family house and is located 65 m above sea level. As a result it is more reminiscent of a high-rise building. In Semco Maritime this contract was handled mainly by the Wind, Oil & Gas Division, with project participation from Products & Technology.
