I didn't expect her trials to last this long.
On one 13.000 TEU vessel that my company had with the waste heat recovery system, the trials lasted 1 week. It was the 1st ship in the series, and many things did not run smoothly. So, these 7 days were more than planned.
My personal experience with sea trials includes much shorter ones: two, two-and-a-half days...

I guess MMM really wants to cross all the i's and dot all the t's...(or something like that)... :)

Each recent day I have been checking how the trials phase for Mærsk Mc-Kinney Møller is progressing, and have been curious to find that she is still undergoing testing at this moment, as shown on AIS, off the Korean East coast, after a week or so. This seems a very long period of testing, but taking into account Maersk's investment in this class of (potentially) 30 ships, maybe it is not so surprising that the testing is so rigorous.
New technology for the shipyard staff as well as Maersk's must be generating a huge amount of data!

The length of the trials phase has been described in the South China Morning Post:

"These reductions, which should be verified during the *** 12-day sea trials***, will be achieved by more efficient twin engines recovering waste heat, steaming at slower speeds, a boxy hull design and an improved propulsion system."

Always not the MONSTERS are ugly !!!!but surely motrousely....

I didn't see her going out on her sea trial, but weather was (and still is!) really bad...so I will try to get her when she comes back. As for the question of ugliness...I guess it is just a matter of getting used to the looks of new megaboxers.

Thanks, lappino, for your new shot of this ship. Apparently she was on trials today (in less than perfect weather conditions from a shipspotting point of view) according to some photos in Danish media.
And which ships are ugly? Stupid question and stupid discussions/comments! However, to be frank: to me all ships built since the Scandinavian viking ships are "quite ugly" :-)

Thanks for posting yet another photo of this giant. Ugly, yes but remember, ships are built to earn money and not to look good :-)

Indeed, monstrously big and monstrously ugly.

The ask is how this era will be named in the future? perhaps the MONSTER age.....
