Sovereign Maersk-class container ship

The Sovereign Maersk class is a series of nine container ships built by Odense Steel Shipyard in Denmark for Maersk Line, with a maximum theoretical capacity that Wikipedia puts at around 9,640 twenty-foot equivalent units. The lead ship, Sovereign Maersk, was delivered in September 1997 under yard number L160, followed by Susan Maersk in December 1997, and the ship list includes the Sally Maersk in March 1998 and the Clifford Maersk in October 1999. A January 2000 FreightWaves report calls the Sovereign Maersk the first of nine ultra-large S-class containerships nominally of 6,600 TEU, and a ship profile records that the Sovereign Maersk was built at Odense in 1997 with a capacity of 8,160 TEU, so the capacity depends on the source and the date.
