Emma Mærsk is a container ship owned by the A.P. Moller-Maersk Group. When she was launched, Emma Mærsk became the largest container ship ever built, and as of 2006 the longest ship in use. The largest ship ever built was the supertanker Knock Nevis, now retired. Officially, Emma Mærsk is able to carry around 11,000 TEU in the calculation of the Mærsk company<ref>Odense Steel Shipyard (2006-12-08). Namegiving of newbuilding L 203.

[edit] Capacity

In normal calculation, her cargo capacity is much bigger — between 13,500<ref>Alexander Bakker (2006-09-12). Big, bigger, biggest. port of Rotterdam.</ref> and 14,500 TEU.<ref>Bent Mikkelsen (2006-08-29). “Emma Mærsk”– the world’s largest. The Scandinavian Shipping Gazette.</ref> The difference between the official and estimated number results from the fact that Mærsk calculates the cargo capacity of a container ship by using the number of containers with a weight of 14 tons that can be carried on a vessel. For the Emma Mærsk, this is 11,000 containers.<ref>Giant Christmas goods ship docks, BBC News, November 5, 2006</ref> Other companies calculate the cargo capacity of a ship according to the maximum number of containers that can be put on the ship, independent of the weight of the containers. This number is always greater than the number calculated by the Mærsk company.

[edit] History

The ship was built at the Lindø Yard in Denmark and named in a ceremony on August 12, 2006. The ship is named after Emma Mærsk, Mærsk Mc-Kinney Møller's late wife. She set sail on her maiden voyage on 8 September 2006 at 02:00 hours from Aarhus, calling at Gothenburg, Bremerhaven, Rotterdam, Algeciras, the Suez Canal, and arrived in Singapore on 1 October 2006 at 20:05 hours.

Emma Mærsk departed Singapore the next day, headed for Yantian in Shenzhen. She sailed on to Kobe, Nagoya, arrived at Yokohama on 10 October 2006, and will return via Yantian, Hong Kong, Tanjung Pelepas, the Suez Canal, Felixstowe, Rotterdam, Bremerhaven, Gothenburg and finally to Aarhus, with arrival at that port 11 November 2006 at 16:00 hours.

[edit] Engine and the environment

The Emma Mærsk is powered by an engine weighing 2,300 tons capable of an impressive 110,000 horsepower. With the massive engines, further actions were taken to protect the environment. This includes recycling the exhaust, mixed with fresh air, back into the engine for reuse. This not only increases efficiency by as much as 12% but also reduces engine emissions<ref name="pop-sci-dec-2006-pg24"/>. Instead of biocides, used by much of the industry to keep barnacles off of the hull, a special silicon-based paint is used<ref name="pop-sci-dec-2006-pg24"/>. This increases the ships efficiency by decreasing drag while also protecting the ocean from biocides that may leak into the ocean.

[edit] Sailing Schedules

Regular trips will involve a route commencing from Aarhus to Bremerhaven, Rotterdam, Algeciras, the Suez Canal, Singapore, Kobe, Nagoya, Yokohama, Yantian, Hong Kong, Tanjung Pelepas, the Suez Canal, Felixstowe, Rotterdam, Bremerhaven, Gothenburg and back to Aarhus.

A complete schedule is available - here listed from the start (registered September 21, 2006, Suez Canal), until 14 Jan 2010.
