|Heavy lifting vessel Svanen in Øresund this morning.|
The heavy lifting vessel Svanen was an impressive sight this morning when it passed Hittarp in the Sound on its way to the Baltic Sea.
The 102.75 x 89.50 Svanen, owned by the Dutch company Ballast Nedam, has a hoisting height (above deck) of 76 m and a lifting capacity of 8700 tonnes.
This is how Ballast Nedam describes their "Swan":
And the jewel in our crown is the 8700-tonne heavy lift vessel Svanen.
As a part of our offshore working method - producing prefabricated elements on land and installing them at sea - we required specific heavy lift equipment. Existing floating sheerlegs were used for the Zeeland Bridge. The Ibis had to de developed for the King Fahd Causeway. This vessel lifts from its centre of gravity, which eliminates much movement of the hoisting load. Following on from this principle, the self-propelled heavy lift vessel Svanen was designed and built for the Storebaelt Bridge in Denmark. Svanen was then enlarged and its lifting capacity further increased to an impressive 8700 tonnes to meet the heavier demands for the Confederation Bridge.
Although originally designed for assembling prefabricated bridges, including the installation of concrete gravity based foundations, this self-propelled catamaran is equally at home in new wind farms, positioning the huge submerged monopiles on which the turbine towers stand. Its lifting capacity is more than sufficient for today's monopiles, which weigh up to 600 tonnes, and its massive dimensions guarantee a stable platform for offshore ramming work. In fact, the Svanen is ready to take on the next generation of monopiles, which will support 5-7 MW turbines weighing 600-800 tonnes and stand in up to 40 metres of water.
