'''''Emma Mærsk''''' is the first [[container ship]] in the {{sclass2|E|container ship|4}} of eight owned by [[Maersk|A.P. Møller – Mærsk A/S]]. When launched in 2006, she was the largest container ship ever built, and in 2010, she and her seven [[sister ship]]s were among the [[List of largest container ships|longest container ships]]. Officially, she is able to carry around {{TEU|11,000|first=yes}} or {{TEU|14,770}}, depending on definition. In May 2010, her sister ship {{ship||Ebba Mærsk}} set a record of 15,011&nbsp;TEU in [[Tanger-Med]], [[Tangier]].<ref name="IngEbba">{{cite web|author=Julie Holt|title=Ebba Mærsk beats world record|url=http://ing.dk/artikel/109254-ebba-maersk-slaar-verdensrekord-i-containerlast|work=Ingeniøren|date=28 May 2010|access-date=11 June 2010|archive-date=31 May 2010|archive-url=https://web.archive.org/web/20100531061343/http://ing.dk/artikel/109254-ebba-maersk-slaar-verdensrekord-i-containerlast|url-status=live}}</ref>

==History==
''Emma Mærsk'' was built at the [[Odense Steel Shipyard]] in [[Denmark]]. In June 2006, during construction, [[welding]] work caused a fire within the [[superstructure]].<ref name="emmafire">Miranda Max.

She was named in a ceremony on 12 August 2006, after [[Mærsk Mc-Kinney Møller]]'s late wife, Emma. On 16 August 2006, five tugboats dragged ''Emma Mærsk'' from her Danish shipyard and towed her backward to the sea.<ref>{{Cite news|url=https://www.wsj.com/articles/the-megaships-that-broke-global-trade-11603384311?page=1|title = The Megaships That Broke Global Trade|newspaper = Wall Street Journal|date = 22 October 2020|last1 = Levinson|first1 = Marc}}</ref> 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.
