The 100 meter long self-propelled barge Duernstein grounded onto a sunken wreck on the Danube River near Regelsbrunn, Austria.  The Duernstein with an attached barge struck a vessel than sank in November 2010.  Authorities have stated the wreck was to be dismantled in January 2012 as it poses a risk to navigation.  Initially, the sunken vessel was to be raised, but it will be cut into several sections.   The Duernstein will be salvaged when the river level rises to allow the vessel to pull free without risk of puncturing the hull.  No reports of injuries or pollution being released.  The location of the wreck is in the Danube-Auen National Park.
