Hull was built as a floating crane under yard No 268 by the Astano Shipyard in El Ferrol, in Spain for the Ballast Nedam Group in the Netherlands on behalf of the Storebaelt Group. She was fitted out and completed by the yard of Grootint, Zwijndrecht, the Netherlands under yard no 40587.
She was built to assist in the construction of the West Bridge in the Great Belt in Denmark.
Launched 1991 as the SVANEN.
Tonnage 11388 grt, dim. 98.0 x 65.1m, length bpp 94.0m.
Propulsion and power 2 x 1250 KW azimuth thrusters at the rear, 2 x 2400 KW azimuth thrusters at the bow, 2 x 750 KW bow thrusters at the bow.
Speed 7.0 knots with no wind, 2.8 knots with 12 m / s wind at 10 meters above water level.
1991 Completed
The SVANEN is a floating crane, commissioned by the European Storebælt Group to be used in the construction of the West Bridge of the Great Belt Link. European Storebælt Group was a joint venture for the construction of the Great Belt Bridge (Storebælt) in Denmark. Ballast Nedam was the lead party for this joint venture. The ship is now mainly used for the construction of wind turbine parks at sea.
Description
The Dutch Gusto Engineering's design with its 8700-tonne lifting capacity makes it one of the world's most powerful floating cranes. It was equipped with, among other things, the bridge, winches, and the engines of the lifting vessel OSTREA that was used in the construction of the Oosterscheldedam in the Netherlands. There are three more vessels with a higher lifting capacity, namely the THIALF and the SAIPEM 7000, and the most recent, the SLEIPNIR. But all three are equipped with two cranes that together have a higher lifting capacity, but only do not exceed 18,000 tons respectively (SLEIPNIR in tandem crane). However, these ships are a lot more seaworthy and not at all comparable to the SVANEN.
History
The SVANEN was developed by Ballast Nedam and built-in 1990-1991 at Grootint in the Netherlands to be used in the construction of the Great Belt Bridge in Denmark. Subsequently, the SVANEN was purchased by Ballast Nedam Equipment Service, Nieuwegein, Netherlands, not renamed, and, after a thorough renovation, used in 1994-1995 for the construction of the Confederation Bridge in Canada. It was later adapted for the construction of the Oresund Bridge between Copenhagen (Denmark) and Malmö (Sweden).
After several years of unemployment in the port of Malmö, the ship was towed to Rotterdam in 2005 to be adapted again, but now for the construction of the Offshore Windpark Egmond aan Zee NoordzeeWind in the North Sea. Subsequently, the SVANEN was used for the construction of the foundations of several offshore wind farms in Europe. In total 395 foundations for offshore wind farms have been installed by the SVANEN. The largest piles were about 70 meters long, had a diameter of 6 to 6.5 meters, and weighed up to 930 tons (as of December 2013).
In November 2014, Van Oord took over the offshore division, including the SVANEN, from Ballast Nedam for an undisclosed amount. This strand provides services for the construction of offshore wind farms. In addition to the jack-up vessel, Van Oord will also be gaining approximately 50 maritime construction personnel.
Her tonnage is now given as 14,220 grt, 7,871 dwt, dim 102.8 x 71.8 x 6.0m (draught)
Load Capacity 8,700 ton.
Accommodation for 50 persons.
Owned by Van Oord N.V. Rotterdam, under the Bahamas flag and registry IMO No 9007453
May 2021 Her last position was in the port of Vlissingen (Flushing), Netherlands, same name and owners.
