The 110 meter long self-propelled tanker barge Pallas allided with a bridge on the Zwarte near Hasselt, Netherlands.  The Pallas was passing under the bridge, but was unable to lower the wheelhouse before the vessel struck.   The wheelhouse was completely destroyed, but the three crew on board were uninjured.  A small amount of smoke appeared after the allision, but no fire.   The Pallas was loaded with 2300 tons of diesel fuel at the time.  No reports of any pollution released.  A tug arrived later and pushed the disaled Pallas to a nearby quay.  The Pallas had left  Zwartsluis and was en route to the port in Zwolle.
