Osage Repowers with Laborde and Mitsubishi
Although the basic design of inland towboats has not changed in decades, there is a revolution in their propulsion systems. To meet strict environmental regulations while minimizing operating costs, Osage Marine Services has once again turned to Laborde Products to supply state-of-the-art Mitsubishi engines to repower a harbor tug. Jackie Sue was refitted with twin Mitsubishi S12A2-Y2MPTK engines rated 940 hp at 1,940 rpm. This is the second such project for the St. Louis, Missouri, fleeting company, with nine more on the horizon.
Mitsubishi Engines for Chem Carrier
Chem Carriers, the Sunshine, Louisiana-based cargo carrier, once again chose Mitsubishi engines for its new M/V Dorella Banta. The 70 ft x 28 ft x 10 ft, 131-ton towboat was built by Rodriguez Boat Builders. The twin engines, supplied by Laborde, are Mitsubishi S12A2 series rated at 850 hp at 1,940 rpm. The 12-cylinder, 34-liter engines are EPA compliant. The vessel is equipped with 7:1 reduction gears, allowing the engines to turn 75 inch x 73 inch four-blade stainless steel propellers in a 76 inch Type 19A Kort Nozzel.
