The Mosel-Saar-Lahn Waterways and Shipping Authority (WSA) announced that ships will probably not be able to sail on the Moselle again until spring. This is because both gate wings of the lock were completely torn from their anchoring and deformed in the accident on Sunday afternoon.
Continuous shipping traffic is currently not possible on the Moselle as there is only this lock chamber for large ships at the Müden barrage. Around 70 ships are stuck on the Moselle and cannot leave the river in the direction of the Rhine. They are reportedly jammed all the way back to the French border and the Saar.
