Shipyard LA BARCA DEL PESCADOR has begun the design of the first tugboat using renewable technologies with Wartsila 20DF engines with methanol
This shalow water ( 1.83 m ) ,double hull tugboat, quadruple-propeller tugboat, one with a total length of 46.2 m and a beam of 19 m, will push convoys of barges of 250 m in total length and 48000 tons of maximum deadweight, on inland waterways in the Paraná waterway -paraguay
These pusher tugs have a bollard pull of 65 tonnes
The hull, machinery casing, deckhouse, wheelhouse and funnels are made of welded steel. The hullform was designed to include a tunnel stern to permit the fitting of large-diameter propeller to maximise propulsive efficiency in shallow waters.
The shallow draught constraint meant utmost attention was paid to weight control throughout the design and construction of every aspect of these vessels.
MC-ASD S.A. performed extensive analysis of the naval architecture to meet the demands for manoeuvrability and fuel economy, and to comply with the crash-stop requirement. The hullform, tunnel geometry and propulsive components were optimised in the experience channel of the engineering faculty of Buenos Aires for those specific requirements.
