On the afternoon of September 28, the 110 meter long self-propelled passenger ship Carmen (MMSI: 244070771) released pollution on the Danube at the Regensburg lock, Germany. The Carmen was proceeding to Cologne from Passau when it released oil pollution into the water. Authorities placed booms around the vessel while the crew determine the source of the pollution. The crew would eventually find the source from a fault.  The water police detained the vessel until repairs could be made.  Authorities stated the amount of oil pollution released into the water was only 2 to 3 liters of oil.  Reports state the oil pollution had been initially detected when the Carmen had locked through the Geisling lock, but the crew was unable to determine the source. No reports of injuries or damage to the vessel.
