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.
