The innovation is an installation ship from the Belgian company GeoSea.
General
The ship was ordered from the Polish Crist shipyard in Gdynia in 2010 by Beluga Hochtief Offshore , a joint venture of the Beluga Group and Hochtief , and built there under hull number 142/1. The keel was laid on November 15, 2010, the launch on June 25, 2012. The ship was completed on July 31, 2012. The ship was put into service in August 2012 and christened on September 3 in Bremerhaven. Around 200 million euros were invested in the construction.
The ship was designed by the Overdick design office from Hamburg in collaboration with Wärtsilä Ship Design.
After the bankruptcy of the Beluga Group, the 100% DEME subsidiary GeoSea from Belgium joined the joint venture with Hochtief on June 1, 2011 with a 50% stake . The name of the joint venture is now HGO InfraSea Solutions.
The ship is used to build wind turbines in offshore wind farms and has been used since mid-September 2012 to build the offshore wind farm “ Global Tech I ” in the German exclusive economic zone in the North Sea . Since October 2017 the ship has been used for the construction of the “ Horns Rev 3 ” wind farm .
In 2015, Hochtief sold its shares in the innovation to its long-term partner, the DEME subsidiary GeoSea.
Technical data and equipment
The ship is powered by diesel-electric technology . The power for the four electrically driven propeller pods is generated by six diesel generator sets, each with an apparent power of 5400 kVA . Furthermore, a main generator with 1950 kVA and an emergency generator with 885 kVA apparent power were installed. The diesel generators work on a medium voltage of 6600 V and are set up in separate rooms. The medium-voltage switchgear is also housed in two separate rooms for reasons of redundancy.
The four electrically driven propeller pods from Schottel, equipped with Kort nozzles , are located in the stern area. The ship reaches a speed of 12 knots . In the bow area there are three cross-beam control systems . The ship thus has a system for dynamic positioning .
The superstructures are in the front part of the ship. A helideck is installed on the port side above the deckhouse . There are accommodations on board for 100 people including the ship's crew . The cabins can be used as single or double cabins.
Behind the deckhouse is the 3,400 m² working deck. The ship can load up to 8,000 tons . It is equipped with four lifting legs with which it can work in water up to 50 meters deep. The ship can be used at a wave height of up to two meters.
The Liebherr -Schwerlastkran which in Nenzing / Austria constructed and in Rostock from Liebherr MCCtec Rostock was manufactured, is located on the starboard side of the ship. With a delivery of up to 31.5 meters, it can lift 1,500 tons. The boom is 105 meters long and the lifting height above deck is 120 meters. The dead weight of the crane, which was installed so that it can rotate 360 ° around one of the four lifting legs of the ship, is 1500 tons. The crane is driven electro-hydraulically. The drive power is 4000 kW .
