AUGUST 7, 2013 — Recently delivered to Harley Marine Services, Seattle, the tug Silver is the second of two 75 ft x 29 ft, 2,000 hp tugs ordered from shipbuilder Conrad Industries, Morgan City, LA, and is the sister vessel to Harley Marine Gulf's tug, Lightning. Both tugs are named after horses ridden by famous cowboys and each is equipped with two Cummins K38M Tier II engines, along with Twin Disc MGX5321 reduction gears. Electrical supply is by two Cummins 85 kW generators and the tugs feature Nabrico Hydra Electric winches.
Silver underscores Harley Marine's commitment and dedication to the environment in all aspects of company operations. Compared to Tier 0 engines, Silver's Tier II engines reduce the production of Nitrogen Oxides (NOx) by 47%. Harley Marine estimates that this will mean a 22 ton reduction in 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. Each tug will be built with technically and environmentally advanced equipment to meet the specific needs of Harley Marine's customers and expanding business markets.
