By the way: The late Mærsk Mc-Kinney Møller was born on 13 July 1913 at Hellerup, just outside Copenhagen.
I would not at all be surprised if ML registered the ship at Hellerup and tried to christen her on 13 July 2013, Mr Møller's 100th birthday, at Copenhagen. If the carrier deploys the ship to the AE10, which calls at Goteborg, Aarhus and Gdynia anyway, it could match very nicely.
Assuming that delivery takes place contractually 1st of June (just a guess) > bingo!
Since I am sure Maersk's new social media people read along here: C'mon Maersk you can do it :-) I'd even go to Copenhagen to see that on the condition that Maersk provides me with a free glass of bubbly in late Mærsk Mc-Kinney Møller's honour.
