Cenac Towing 32
O.J. Cenac is a big boat, at 130 x 38 ft. with a 15-ft. molded depth. The new boat marks a milestone for both Cenac and Cummins as it is the first tug into service with Cummins' new QSK60 engines. With three of these new engines, each turning its own propeller, the O.J. Cenac. will work as an 8,000-hp classed vessel. The engines turn into
Twin Disc MG DR5600 marine gears with 7:1 ratios. The 90-in. props are enclosed in kort nozzles that have been faired into the hull to maintain the boat's 12-ft. working draft. The massive props are mounted on nine-in. shafts equipped with Kobell 527A shaft brakes. Steering to the boat's three rudders was supplied by St. Rose. La.-based EMI. The elec- tronic clutch and throttle controls were supplied by Twin Disc. There is an Alfa
Laval SB 104 centrifuge through which fuel is pumped. The centrifuge is also employed to circulate fuel in the tank.
Accommodation for a crew of up to 12 people is provided in a traditionally styled three level deck house.
Auxiliary power employs two
Cummins 6CT-powered 130 kW gener- ator sets in addition to a Cummins
QSMI1 for the boat's Intercon winch.
The waterfall-type winch has a capacity of 3.000 ft. of 2.5-in. wire per drum and 315,000 pounds of line pull.
The boat has a fixed onboard C02 fire suppression system for unmanned machinery and cargo spaces and is built to an ABS load line but is not classed.
The boat will tow a 425 by 70-ft. 50,000-barrel barge in deep water Gulf of Mexico service.
Leroy Molaison, of Main Iron Works in Houma, explains that this boat is one of 20 or 25 vessels the two companies have collaborated on.
