Papu Mar

On the night of April 17, the 32 meter long towboat Papu Mar (MMSI: 755103015) sank on the Río de la Plata Punta in the Indio Channel near the Banco Chico reef off Argentina. The Papu Mar was pushing the barge 240-4 carrying 140 containers when the towboat suffered uncontrolled water ingress caused by stormy conditions. The crew was unable to control the flooding and the towboat partially sank by the stern. The nine crew on board were able to evacuate the vessel and seek refuge on the barge. Authorities would later rescue the crew and safely transferred them to Port of La Plata where they would receive medical treatment.

The RN Salvamento dispatched the tug Ona Don Lorenzo (IMO: 9328388) to assess the situation. The tug was found the Papu Mar had completely sunk, but still connected to the barge. The barge would later be uncoupled and towed to Buenos Aires. Authorities were monitoring the sunken towboat for any potential release of pollution. Reports state the vessel owners were arranging the refloating of the Papu Mar. Authorities have launched an investigation into the incident.
Local news reports state the towboat had possibly made an error in judgement to cross the river during the storm. There are suggestions that the rudder room or excessive listing may have allowed water to flood the vessel.
