Incat Crowther recently delivered the Glenn Autry, a 205’x32’x7’6”, 561-dwt aluminum monohull fast crew-supply boat to Barry Graham Oil Service, Bayou La Batre, Ala. Built by Halimar Shipyard, Morgan City, La., the Gene Autry is the second vessel to come out of collaboration among the three companies, following the sister ship John Jacob delivered in 2014.
Main features of the vessel include its 3,640 sq. ft. aft deck with a cargo capacity of 450 long tons, and a main deck cabin with 72 passengers seats, shower and toilet. There is a dedicated dynamic positioning equipment room, stores and access to the upper wheelhouse and below deck, where twin cabins accommodate up to 12 crew members. Adjacent to those cabins is the crew galley, mess area and pantry.
The wheelhouse has forward and aft facing control stations. A deck locker accessible from the cargo deck holds securing gear and safety equipment.
Propulsion power comes from four Cummins QSK 50 diesels, compliant with EPA Tier 3 emission standards, each rated at 1,800 hp. The engines turn four Hamilton HM811 waterjets through Twin Disc MGX 6848 gearboxes via cardan shaft assemblies from Driveline Service, Portland, Ore. The combination gave the Gene Autry a top speed of 35 knots during acceptance trials.
The vessel is certified for Coast Guard Subchapter T service and American Bureau of Shipping classed for DP-2 service. Three Thrustmaster 150 hp tunnel bowthrusters are used in combination with the waterjets for maneuverability, controlled by a Beier Radio DP-2 system. Ship’s service power comes from a trio of Cummins QSB7-DM generators rated at 185 kW.
A FiFi-1 firefighting system provides capability for fighting off-ship fires, with remote controlled monitors and two FFS engine driven pumps, each with 5,300-gpm capacity and integral clutch assemblies.
Tankage includes 15,296 gals. fuel; 17,484 gals. of transferrable fuel; and 42,588 gals. of rig or ballast water in dual-purpose water tanks
