The 80 meter long self-propelled tanker barge Nordwind allided with the Mühlendamm lock gate on the River Spree in Berlin, Germany.  The Nordwind was travelling from Treptow when it suffered a technical fault while entering the lock.  The vessel was unable to stop and struck the gate.  The bow of the Nordwind was holed and the gate was destroyed.  The Nordwind proceeded to berth nearby so it could be inspected.  The lock was closed to traffic until repairs can be completed.
