The Wilh. Wilhelmsen group has just launched its latest vessel, ‘Tønsberg’, built by Mitsubishi Heavy Industries.
Designated the “Mark V”, the vessel is the largest of its kind, with a length of 265 metres and offering a cargo volume of 138,000 cubic metres over six fixed and three hoistable decks.
Four Mark V vessels will be delivered to Wilh. Wilhelmsen and its partner Wallenius Lines. The second vessel will be delivered in August and two in 2012.
The entire cargo hold of the ‘Tønsberg’ is arranged for customer’s high and heavy cargo such as excavators, bulldozers, wheel loaders and harvesters.
With a width of 12 metres and safe working load of 505 tonnes, the vessel’s stern ramp offers customers the possibility to ship larger units, and the clear height of the main deck, 7.1 metres, is also a record for this kind of vessel.
Cargo can also be loaded on the weather deck, which has a ramp from the deck below. Three decks can be hoisted by electric winches to provide maximum flexibility and utilisation.
Following the global trend towards greater environmental friendliness, the Mark V will use 15 to 20 percent less fuel per transported unit than its predecessors, thanks to a optimised hull form and a number of energy saving features such as the streamlined rudder design and duck tail. In the engine room a turbo generator produces electricity from the waste exhaust heat.
A Unitor water ballast water treatment system avoids harmful transfer of microorganisms to the sea. All fuel oil tanks are also protected to minimise the risk of leakage in case of grounding or collision.
MV Tønsberg will commence service in the Wallenius Wilhelmsen Logistics’ round-the-world trade.
