The 55 meter long self-propelled barge Zwaluw sank while moored at a quay in Zeeburg, Netherlands.  No one was on board the vessel at the time and divers were requested to investigate.  The Zwaluw was loaded with 530 tons of gravel at the time of the incident.  Authorities placed oil booms around the sunken vessel to contain a small amount of pollution released when the vessel sank.  Reports state the vessel will be lifted and repaired.
