Odense Steel Shipyard was a Danish shipbuilding company located in Odense. It was best known for building container ships for its parent group, A.P. Moller – Maersk Group, including the Mærsk E-class in 2006 which at the time were the biggest container ships in the world. The global financial crisis led to Maersk announcing its closure in 2009 and the last new ship was delivered in January 2012.
