Emma Mærsk is the first container ship in the E-class of eight owned by the A. P. Moller-Maersk Group. When she was launched in 2006, Emma Mærsk was the largest container ship ever built. As of 2010, she and her seven sister ships are the longest container ships constructed and the longest ships currently in use, after the largest ship ever built, Seawise Giant, was permanently moored in 2004 and scrapped in 2010. Officially, Emma Mærsk is able to carry around 11,000 Twenty-foot equivalent units (TEU) or 14,770 TEU depending on definition. In May 2010, the class set a record of 15,011 TEU in Tanger-Med, Tangiers on sister Ebba Mærsk.
