The 135 meter long self-propelled barge Sandra W ran aground on the Rhine River near Mainz, Germany. The Sanda W was en route to Budapest from Tolkamer and had reached the mouth of the Main River. The barge was attempting to enter the Main when the river cruise ship River Ambassador appeared from under a nearby railway bridge. The vessels nearly collided, but luckily the Sandra W was able to do an emergency maneuver avoiding it. However, the maneuver sent the Sandra W into a fairway buoy before the barge touched the river bottom. No reports of injuries, damage or pollution released. The River Ambassador continued on its voyage to Nuremberg from Mannheim while the Sandra W continued to Budapest.
