MV Tønsberg is a roll-on/roll-off ship owned by Wilh. Wilhelmsen. As of 2012 it is the largest RORO ship in the world.[5]

Specification

  • Dimensions: MV Tønsberg is 265 m (869 ft) length overall and 32.26 m (105.8 ft) wide, and has 11 m (36 ft) draught and 46 m (151 ft) of air draught. Gross tonnage is 76,500 gt. Capacity is 5% – 7% higher than Mark IV roro ships.
  • Decks: Six fixed decks and three hoistable ones (4B, 6 and 8, lifted by electric winches). The main deck can take loads 7.1 m high – more than other vessels – allowing very large loads. The total deck space is 50,335 m2 and cargo volume is 138,000 m³. Internal ramps are 8 metres wide; The weather deck (which can be used for outsize or unusual loads, such as wind turbine blades) also has a 4m wide ramp from below, to reduce the need for cranes.[6]
  • Stern ramp: The stern ramp is 12 m (39 ft) wide and can take loads of 505 tonnes.
  • Design: Hull form has been improved, so compared to previous ships it will use 15 – 20% less fuel per unit of cargo.[2] Stability has been improved, to reduce the need for ballast water. There is a double bottom and Deck 5 is also watertight.
  • Propulsion: 7-cylinder MAN B&W engine, which has been derated from 22,890 kW[4] to 20,100 kW MCR at 108rpm; (although normal output in service is 18,090 kW), driving a 7.3 m (24 ft) diameter 6-bladed propeller; plus two 2,500 kW Kawasaki thrusters (one each at the bow and the stern). Service speed is 20.25 knots.[7]

History

MV Tønsberg is the fourth Wilhelmsen ship to carry this name; it's named after the Norwegian coastal town where Wilhelmsen was founded in 1861.[8] It was built to celebrate the 150th anniversary of Wilh. Wilhelmsen line. It is the first in a series of four "Mark V" ships, built in 2010-2011 by Mitsubishi Heavy Industries shipyard in Nagasaki, in Japan.[7] The second ship of the class, Parsifal, was delivered in September 2011.[9]

In June 2012, Tønsberg was awarded "Ship of the Year 2011" by the Japan Society of Naval Architects and Ocean Engineers, recognising its efficiency and environmental compatibility.[10]
