On Monday 2nd April, 2012, TSAVLIRIS dispatched tugs "DOMINGO B" and "ARGENTINO 1" from Buenos Aires and La Plata respectively, to the assistance of Bulk Carrier "SAMJOHN LIBERTY" (38,846 GRT, 74,761 DWT), laden with 47,240 MT of soya bean meal in bulk, which had grounded at about 290km Rio Parana.

The Coastguard ordered several vessels to remain anchored at Common Zone for as long as the "SAMJOHN LIBERTY" was grounded as she was obstructing the channel.

On the 2nd April TSAVLIRIS salvage master arrived on the scene of the casualty and the tugs arrived on the 3rd April. Attempts to refloat the vessel were immediately undertaken but with no success. A third and more powerful tug boat, "YAGAN", was dispatched from Buenos Aires on the 4th April, and arrived the next day.

The casualty was successfully refloated on the 5th April with the assistance of the three tugs and anchored at San Pedro Roads for the mandatory post grounding inspection by the Coastguard. Following clearance by the authorities, the convoy proceeded down river and arrived at Zona Comun. Casualty safely redelivered to her owners on Thursday 5th April, 2012.
