Maersk Mc-Kinney Moller (Danish: [ˈmɛɐ̯sk məˈkʰini ˈmølɐ]) is the first ship of Maersk Line's Triple E class of container vessels. At the time of its entry into service in 2013, it had the largest cargo capacity in twenty-foot equivalent unit (TEU) of any vessel, and was the longest container ship in service worldwide.^[3][10] Constructed for Maersk by Daewoo Shipbuilding & Marine Engineering (DSME) of South Korea, it was launched in February 2013 and began operational service during July 2013. It was named for Mærsk Mc-Kinney Møller, the CEO of Maersk from 1965 to 1993.^[11] The ship is the first of a class of 20 identical vessels.^[4]

Close

Maersk Mc-Kinney Moller was the world's largest and most efficient operational container ship at the time of its completion, totalling 399 metres (1,309 ft 1 in) in length and with a cargo capacity of 18,270 TEU containers.^[12] Its efficiency is maximized by fuel-efficient engines and a maximum speed of 23 knots (43 km/h; 26 mph), reducing its fuel consumption and carbon dioxide emissions by 20 percent compared to the previous most efficient cargo vessel.^[12] However, due to its size, cost, and use of twin engines, its efficiency is reduced severely if it is not fully loaded; the shipping analyst Richard Meade asserts that it is "probably the most inefficient ship ever built" when loaded to less than 50%.^[13] During normal operations, Maersk Mc-Kinney Moller is manned by a crew of 19, although it has sufficient accommodation for 34 crew.^[8]

The contract for the construction of Maersk Mc-Kinney Moller was signed on 21 February 2011.^[1] Work began with a steel cutting ceremony at the DSME shipyard at Okpo, Geoje, South Korea, on 18 June 2012.^[14] The hull was laid on 27 November 2012 and the boat was officially launched on 24 February 2013.^[1]

The Maersk Mc-Kinney Moller left the Daewoo shipyards in an operational capacity in July 2013, whereupon it began sea trials.^[15] Initially, it was forced to operate at much less than its maximum cargo capacity, as most ports certified to handle Triple E-class vessels at that time lacked gantry cranes tall enough to load the ship completely.^[15][13] In August 2013, it made its first transit of the Suez Canal.^[9] In January 2014, the Maersk Mc-Kinney Moller arrived at its first operational port of call, Singapore.^[16] In November 2014, the Maersk Mc-Kinney Moller was superseded as the world's largest container ship by China Shipping Container Lines' CSCL Globe.^[17]
