MV Tønsberg is a roll-on/roll-off ship owned by Wilh. Wilhelmsen. When built, it was the largest RORO ship in the world.{{cite news|url=http://www.logisticsmanager.com/Articles/Article.aspx?liArticleID=15772|archive-url=https://archive.today/20130127230621/http://www.logisticsmanager.com/Articles/Article.aspx?liArticleID=15772|url-status=dead|archive-date=27 January 2013|accessdate=1 July 2012|title=Wilhelmsen launches largest ro-ro ship|work=Logistics Manager}}
Specification
- Dimensions: MV Tønsberg is {{convert|265|m|ft|abbr=on}} length overall and {{convert|32.26|m|ft|abbr=on}} wide, and has {{convert|11|m|ft|abbr=on}} draught and {{convert|46|m|ft|abbr=on}} of air draught. Gross tonnage is 76,500 gt. Capacity, at 5,990 cars, 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.{{cite news|url=http://www.heavyliftpfi.com/content/newsitem.aspx?id=2679|accessdate=1 July 2012|title=Wilh.

- Stern ramp: The stern ramp is {{convert|12|m|ft|abbr=on}} 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.{{cite web|title=Wilh.

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.{{cite news|title=Utsatt dåp for verdens største RoRo skip|url=http://www.skipsrevyen.no/nyheter/135817.html|accessdate=1 July 2012|newspaper=skips-revyen|date=17 March 2011|url-status=dead|archiveurl=https://web.archive.org/web/20120624025310/http://www.skipsrevyen.no/nyheter/135817.html|archivedate=24 June 2012}} 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. The second ship of the class, Parsifal, was delivered in September 2011.{{cite news|url=http://www.heavyliftpfi.com/content/newsitem.aspx?id=3322|archive-url=https://archive.today/20130125015144/http://www.heavyliftpfi.com/content/newsitem.aspx?id=3322|url-status=dead|archive-date=25 January 2013|accessdate=1 July 2012|title=Parsifal hits new notes for heavy lift|work=Heavy Lift & project Forwarding International}}
