for her. Going eastwards on 1 February 2013, she suffered a damaged stern thruster and took on so much water in the Suez Canal that she became unmaneuverable. Tugs, anchors and the wind took her to Port Said to offload 13,500 containers, drain her and be investigated by divers. She had not been in danger of sinking. On 15 February 2013, the Maersk Line confirmed that she was about to leave Port Said under tow to a yard for further assessment and repair. On 25 February she reached the yard of Palermo,

Capacity

Originally Maersk reported a capacity of 11,000 TEU ( twenty-foot equivalent units) as the maximum capacity of fully loaded 14 ton containers, according to Maersk company's then method of calculating capacity, which, at her introduction into service, was about 1,400 more containers than any other ship. However, Maersk also acknowledges the standard method of defining capacity, stating 14,770 TEU.Vessels
''Maersk Line'', 1 June 2010; accessed 16 June 2010.
By normal calculations, she has a capacity significantly greater than reported—between 13,500 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), i.e. 11,000+ containers, of which 1,000 can be refrigerated containers.Røe, Magne A
