Emma Maersk is a container ship owned by the A. P. Moller-Maersk Group. When she was launched, Emma Maersk was the largest container ship ever built. As of 2009 she and her 7 sister ships are the longest container ships constructed and the longest ships currently in use. Officially, Emma Maersk is able to carry around 11,000 twenty-foot equivalent units (TEU) according to the Maersk company's method of calculating capacity, which, at her introduction into service, was about 1,400 more containers than any other ship is capable of carrying. By normal calculations, Emma Maersk's cargo capacity is significantly greater than the listed capacity — between 13,500 twenty-foot equivalent units (TEU) and 15,200 TEU. The difference between the official and estimated numbers is because Maersk calculates the capacity of a container ship by weight (in this case, 14 tons/container) that can be carried on a vessel. The ship was built at the Odense Steel Shipyard in Denmark. In June 2006, during construction, welding work caused a fire within her superstructure. It spread rapidly through the accommodation section and bridge. Emma Maersk was named in a ceremony on 12 August 2006. The ship is named after Emma Maersk, Maersk Mc-Kinney Moller's late wife. The ship set sail on her maiden voyage on 8 September 2006 from Aarhus, calling at Gothenburg, Bremerhaven, Rotterdam, Algeciras, the Suez Canal, and arrived in Singapore on 1 October 2006. The Emma Maersk is powered by a Wartsilä-Sulzer 14RTFLEX96-C engine, currently the world's largest single diesel unit, weighing 2,300 tons and capable of 109,000 horsepower (82 MW). The ship has several features to protect the environment, some of which include exhaust heat recovery and cogeneration. The exhaust gases of the engine are passed through a steam generator which then powers electrical generators to generate electricity. This creates an electrical output equivalent to about 12% of the main engine power output. Some of this steam is also used directly as shipboard heat. Instead of biocides, used by much of the industry to keep barnacles off of the hull, a special silicone-based paint is used. This increases the ship's efficiency by reducing drag while also protecting the ocean from biocides that may leak. The silicone paint covering the part of the hull below the waterline is credited for lowering the water drag enough to save 1200 tons of fuel per year. The ship has a bulbous bow, a standard feature for cargo ships. The Emma Maersk and similar ships have been criticised for their burning of bunker fuel, which has a high sulphur content. Sources in the article estimate the fuel sulphur content at 2.5% to 4.5%, which is over 2000 times more than allowed in current automotive fuel. Edith Maersk is a container ship and the sister ship of Emma Maersk, thus the world's largest cargo ship. It has capacity for 13,500 containers, in spite of calculations from Maersk Line company, that the ship has only 11,000 TEUs capacity. It can reach up to 15,200 TEUs according to specialists.
