RWE Innogy is constructing the Nordsee Ost (NSO) offshore wind farm around 35 kilometres to the north-east of the island of Heligoland in the German North Sea region. With 48 multi-megawatt wind turbines, constructed in water depths of up to 25 metres, the wind farm will have a total output of around 295 megawatts.
The first foundations at the Nordsee Ost offshore wind farm have been installed.more
The main crane of the Victoria Mathias lifts the 550-tonne steel foundations into the water. Whith roughly 40- to 50-metre-long steel piles the foundations are fixed into the seafloor. Then a hydraulic hammer knocks them 40 metres into the earth. After that the foundations are aligned horizontally before being finally anchored in place with special concrete.
The offshore installation vessel Victoria Mathias has arrived at the construction are of the offshore wind farm Nordsee Ost for the first time. During the so-called sea trials the ship is tested extensively before it will subsequently start its work. At the same time, maintenance work was carried out on the metmast.more
The first four jacket foundations for the Nordsee Ost offshore wind farm arrived mid-May at Bremerhaven. They reached the base port by water via a heavy lift pontoon from Verdal in Norway. And further foundations are already on the way: a so called power barge carrying eight foundations is about to arrive in Bremerhaven beginning of June. Each of these foundations is up to 50 metres high and has a total weight of approximately 550 tonnes.more
In a special ceremony, RWE Innogy named its second installation vessels „Victoria Mathias“. Starting in summer 2012, the vessel will help to construct the offshore wind farm Nordsee Ost (295 MW) about 30 kilometres off the German coast. more

After about 60 days on the high seas and having traveled roughly 27,000 kilometres, the first of the two construction vessels, Victoria Mathias, has arrived in Bremerhaven. You can find pictures from the arrival here.more
The production of the first jackup foundations for the construction of the Nordsee Ost offshore wind farm is near completion. The foundations will arrive in Bremerhaven in March already. Current pictures from the production can be found here.more
At the end of November the first components of the jacket foundations for the construction of the Nordsee Ost offshore wind farm reached Bremerhaven. The piles are 50 metres long and are weighing about 100 tonnes each. They will be used to fix the jacket foundations onto the sea bed. more
The construction of our two offshore installation vessels in South Korea is completed. Watch the film and receive an impression about the construction phase of about 450,000 working hours during which over 12,000 tonnes of steel were handled.more
