The ship is the Nora Maersk, owned by the Danish company, Maersk, which is the largest container ship operator in the world.
The Nora Maersk is specifically designed to carry containers, and its capacity is 2200 TEUs (twenty-foot equivalent units) which makes it a medium sized container ship.
[When googling the Nora Maersk to find its capacity, I came across this interesting story about the ship - reported to be sinking in Auckland Harbour].
