Wallenius Wilhelmsen Logistics's MV Tonsberg, the world's largest RoRo vessel, has been named “Ship of the Year 2011” by the Japan Society of Naval Architects and Ocean Engineers (JASNAOE). This is the sixth time that leading Japanese shipbuilders, Mitsubishi Heavy Industries (MHI), has received this prestigious award. 

The Ship of the Year Award forms part of JASNAOE's annual selection of the most technologically, artistically and socially superior ships and marine structures built that year. The MV Tonsberg, which is the first in a series of four vessels ordered from MHI for WWL, was chosen on account of its outstanding transport efficiency and environmental compatibility.
The Mark V class vessel series has proven it's worth in WWL's service,  consistently delivering outstanding value for WWL's customers, as well as for the environment.

The MV Tonsberg provides a flexible, environmentally sound shipping solution for large-size construction machinery and machine tools, plant components, railway cars and pleasure boats. The vessel is equipped with ballast water treatment and waste-heat recovery systems, as well as an electronically controlled engine, making it one of the most fuel-efficient, environmentally sustainable ships on the market. Meanwhile, its electrically hoistable decks also enable it to provide one of the most versatile RoRo cargo solutions in the world today. The 74,622gt ship measures 265m in length, 32.26m in breadth and 33.22m in height.
