This summer, Harley Marine Services welcomed tugboat Silver to its fleet. This tug was built and delivered by Conrad Industries and is the sister vessel to Harley Marine Gulf’s tug, Lightning. Both tugs are named after famous cowboy’s horses and are equipped with two Cummins K38M Tier 2 engines, along with Twin Disc MGX5321 reduction gears.
Silver is powered by 2 Cummins 85kw generators and is outfitted with Nabrico Hydro Electric winches.
When compared to tier 0 engines, the Silver’s tier 2 engines reduce the production of Nitrogen Oxides (NOx) by 47 percent. With this vessel, Harley Marine estimates a 22-ton reduction of annual emissions of NOx.
Harley Marine Services plans to add four more tugs to its fleet this year; the Alamo, the Fury, the Duke and the Stardust. All four tugs will join Harley marine’s expanding fleet in the United States Gulf Region.
