The 86 meter long self-propelled tanker-barge Wervelwind collided head-on with the 105 meter long, 2138 ton self-propelled barge Adolf Blatt on the Neckar River near Landenburg, Germany. The Wervelwind suffered some damage, but the Adolf Blatt suffered a two meter wide hole in the hull. There were no injuries on either vessel. The Wervelwind was proceeding to Landenburg with 350 tons of phosphoric acid while the Adolf Blatt was travelling in ballast. No pollution was released as the Wervelwind is a double-hull tanker. Damage to the Adolf Blatt has been estimated to be around 10,000€. Both vessels were detained by the water police for inspection. An investigation into the incident is being conducted.
