The 70 meter long self-propelled barge Noorderlicht sank on the Rhine River near a lock between Amerongen and Laurik, Netherlands. An exhaust pipe had broken in the engine room allowing water to flood into the vessel.  The stern of the Noorderlicht partially sank while the bow remained above water.  A patch was placed over the leak and the pumps were to dewater the vessel before it can be towed to a nearby shipyard. No reports of injuries.
