TUI Cruises' Mein Schiff 3 is at the centre of a formal German maritime investigation after colliding with two cargo ships as she sailed out of Bremerhaven in stormy weather on Sunday, October 25. The Federal Bureau of Maritime Casualty Investigation (BSU), which sits under the Federal Ministry of Transport, has now rated the incident a 'serious casualty' — the second-highest tier on its five-level scale, below only a 'very serious casualty'.

Details of the incident are sobering when you picture the scene. The ship, carrying 2,428 passengers and 922 crew, struck the MSC Victorine and MSC Anne F while departing the port. Nobody was hurt, and everyone on board disembarked the following morning, but the vessel sustained damage significant enough to knock out the next cruise entirely.

That sailing was a trip to the Canary Islands, which TUI cancelled. Repairs have been handed to Lloyd Werft Bremerhaven, the shipyard practically next door to where the incident happened, with the ship due to move to its pier on Sunday, November 1. TUI said it expected more clarity early in the following week on whether sailings beyond the immediate repair window would also be affected.

The next voyage on the books is a 14-night 'Enchanting Norway' itinerary, sailing roundtrip from Bremerhaven from November 14 to 28. Whether that departs as planned now hinges on how the repairs go and what the investigation turns up.

For anyone booked on Mein Schiff 3 this winter, the practical takeaway is to watch TUI's communications closely and keep booking conditions in mind. The BSU classification signals that German investigators view the incident as substantial rather than a minor scrape, which means the inquiry — and potentially further schedule disruption — could stretch over weeks. Passengers on the cancelled Canaries sailing should already have been contacted about refunds or rebooking; anyone on the Norway departure or later would be wise not to lock in non-refundable flights or hotels until TUI confirms the ship is back in service.

There's a broader reassurance in the facts too: with more than 3,000 people on board in rough conditions, the fact there were no injuries points to the emergency and evacuation procedures working as intended. But it's a reminder that cruise itineraries, especially those departing North Sea ports in autumn, can be upended by weather and port incidents at short notice — travel insurance with trip-cancellation cover is worth having in place before you sail.
