The chart below shows what the DFDS Seaways vessels will look like when repainted in the new colours. Second one down is the Maersk D's. I expect they will wait until the next scheduled refit to repaint the hulls but are making a start by repainting all the funnels in DFDS colours.
Couple of photos below of the funnel on the Maersk Dover, where they have painted the bottom section in DFDS dark blue and will probably put scaffolding up and do the remainder on the next saturday layover.
This is the Maersk Delft passing yesterday with the Maersk stars removed and the scaffolding left up to repaint the funnel in service. The three ships are going to look decidedly odd for the next week or two. Believe the name change is due to be conducted on 12th July.
