Pusher Tugs for the Amazon’s Barge Trade

Posted on May 13, 2005

New engine orders for a specialized tugboat segment. Over the last two years, MAN B&W Diesel A/S, Denmark, has been successful with a total of 19 engine and propulsion package contracts to Brazilian tugboat owners.

Ten medium-speed engines, five of type 6L23/30A-F and five of type 8L23/30A-F, were recently selected for a series of single-screw pusher tugs under construction in Brazil, at the yard of Estaleiro Sao Joao. The vessels were ordered by the owner J.F. de Oliveira Navegacao Ltd, Brazil.

This new MAN B&W Diesel powered series follows another series of six pusher tugs. These vessels are powered by three single-screw, and three twin-screw propulsion packages, type MAN B&W 8L23/30-FKV, ordered by the Brazilian owner Transportes Bertolini Ltda, Manaus.

Both series of tugs will be deployed in the specialized Amazon inland waterways transport system - based on barges. Soya beans, bauxite and trailers from the inland of Brazil and Bolivia are loaded on barges and pushed via the Amazon river system to Santarém and Belém on the Atlantic coast. In Santarém, the barge cargoes of soya beans and bauxite are transferred to overseas trading, ocean-going cargo vessels for the export markets.
