South American Operator Re-Powers with Cummins
Navios South American Logistics Inc. is a provider of river transportation on the Inland Water Ways (IWW) of the Paraguay-Paraná Rivers.
With a fleet of more than 250 barges and 20 well equipped push-boats on the river, the firm also operates sea-going product tankers. Recently they have repowered the first of their push boats, the 30 by 9.5 by 2.7-meter Tomas Romero Pereira, in Paraguay at the Shipyard Aguapé of Asunción city. The IWW Paraná-Paraguay is the most important waterway in South America after the Amazon river system. Serving four nations, more than 15 million tons of bulk, general, and liquid cargo are shipped by barge to or from Argentina, Brazil, Paraguay and Uruguay. There are more than 1700 barges on the IWW and nearly 150 workboats including both push-boats and tugboats
The pushboat Tomas Romero Pereira’s three Yanmar mains and three auxiliaries were replaced with three Cummins KTA19 M3 engines with a total output of 1590 HP. Each engine into Twin Disc 516 gears with 3.96: 1 reduction. These then turn 4 blade 960 x 1248-m/m propellers in ducted nozzles. The towboat’s electric power is provided by a pair of Cummins 6C CP-powered generators each producing 136 kW, 50 Hz. Sea trials on the updated vessel were successfully carried out in September 2012.
