On May 1, Eastern Shipbuilding Group delivered the James Dale Robin to Florida Marine Transporters, Mandeville, La. The 90’x32’x10’ James Dale Robin is the 57th inland towboat constructed by Eastern Shipbuilding and the second of a five towboat option exercised by Florida Marine in 2013.
This ongoing series of towboats originally began with a 25 vessel contract with on-time deliveries starting in 2006. It has expanded to become the largest single towboat build contract in history, the company said. The additional five vessel contract is being constructed from the design furnished by Gilbert Associates, Boston, Mass.
These vessels will be the first in the series with EPA Tier 3 main propulsion engines and generators delivered to Florida Marine. The vessel is powered by two Caterpillar 3512C Tier 3 diesel engines rated at 1,500 hp at 1,600 rpm provided by Louisiana Power Systems. The reduction gears are direct coupled Twin-Disc Model MG-5600 with a 6.04:1 reduction supplied by Stewart Supply, Harvey, La. Electrical power is provided by two 99kW John Deere 4045AFM85 99KW Tier 3 generator sets rated for 60 Hz, at 208 VAC provided by Kennedy Engine Company, Biloxi, Miss. These diesel engines comply with the current EPA Tier 3/MARPOL control of emissions of nitrogen oxides from marine diesel engines.
