Harley Marine Services has expanded its inland waterways operation, which provides petroleum transport and bunkering service. Harley Marine Gulf, Houston, is the Seattle-based operator’s 10th subsidiary company.
In 2012, Harley Gulf took delivery of the 75′ pushboats Thunder and Lightening from Conrad Industries. The Silver Stardust followed in early 2013. In October, three more pushboats were under construction at Conrad’s yard in Morgan City, La., with deliveries scheduled for the end of November, January and March 2014. These 2,000-hp boats will all have the same 29’9″ beam and 9’11” molded depth to give the vessels a 7′ light draft.
Propulsion for these vessels is provided by a pair of EPA Tier 2 compliant K38-M Cummins engines each delivering 1,000 hp at 1,800 rpm connected to Twin Disc MGX5321 gears with 5.96:1 ratios. Cummins Mid-South supplied the engines.
Johnny’s Propeller Shop, conveniently located next door to the Conrad Shipyard in Morgan City, supplied the propellers.
The towboats all have four decks except the Thunder, which had only three decks. Auxiliary power includes a pair of Cummins 6BTA5.9-DM-powered 85-kW generators. The hull has tankage for 30,000 gal. of fuel, 6,000 gal. of water and 200 gal. of lube oil. Nabrico Hydro Electric winches are mounted on deck for handling the barge face wires.
