The 80 meter long self-propelled tanker barge Doina ran aground on the Rhine River near Nonnenwerth, Germany. The tanker had grounded off the tip of the island Freizuschleppen heavily ladden with a cargo of diesel fuel. Unable to free itself, the crew requested assistance. Another vessel attached a towline and tried to pull the Doina free, but the towline snapped. Several other attempts to refloat the tanker also failed. A lighter was requested before another attempt would be made. The tanker Yvonne arrived on scene the following day and offloaded some 500 tons of diesel fuel. Afterwards, the Doina was pulled free by the tug Pilot. Both vessels proceeded to Brohl for inspection. The water police has launched an investigation into the incident. Reports state the cause of the grounding was due to a navigational error.
