18/02/2014 Evwind,
It is a first in the German shipbuilding industry; the Aeolus, the first jack-up vessel for offshore wind farms designed and built in Germany, which was constructed at Sietas Shipyard for the prestigious Dutch marine engineering company Van Oord, has left the shipyard.
Having passed through the Este barrage of Hamburg port, the jack-up vessel now travels along the river Elbe to Bremerhaven.

About the jack-up vessel
The Sietas jack-up vessel has been developed for use in offshore wind farms. It has a carrying capacity of up to 5,600 tons and can work safely in water depths of up to 45 meters. It can load itself, has DP2 equipment (Dynamic Positioning System 2) that positions it very precisely, keeping it stable even in heavy seas, and a jacking system with four stilts that are 84 meters long, each weighing around 1,000 tons and with a diameter measuring 4.5 meters. This means it can stand high above the water surface and ensures a safe working position for installation tasks on the high seas.
The innovative special-purpose vessel is 140 meters long and 38 meters wide, its moulded depth amounts to 9.12 meters, its draught to 5.7 meters. Its speed during service is 12 knots. The diesel-electric drive with four sets of generators delivers a total of 20,000 kilowatts. The special offshore crane can lift a 900-ton load with a jib reach of 30 meters and up to a height of about 120 meters above the water. The installation ship will accommodate 74 crew members during its deployment at wind farms.
In July 2014 the Aeolus will go off on its first charter. It will be used in the construction of Eneco Luchterduinen wind farm off the coast of the Netherlands.
