Marine Propulsion Annual Installation innovations Following a bid process, two Cat 3406 SINA (spark-ignited naturally aspirated) engines were selected for the repower. Significant additions included explo- sion-proof 32-volt alternators with cus- tom mounting brackets, and air-starting motors with non-sparking pinions. The 3406 SINA engines are each rated 215 bhp (161 bkW) at 1,800 rpm. They drive 30 in. x 26 in. (76 x 66 cm) wheels through Twin Disc MG-509 2:1 ratio gears. The repower was completed at Lyon Shipyard Inc. in Norfolk, and the ferry was renamed the James C. Echols in honor of TRT's long-time executive director. The replica sternwheeler, built at Freeport Shipbuilding, Freeport, Fla., in 1982, is 60 ft. (18 m) long, with 22.5 ft. (7 m) of beam, and 3.5 ft. (1 m) draft with a full load of 138 passengers.

New fuel storage, supply, monitoring and alarm systems were developed. Additionally, 20 gas storage cylinders were skid-mounted on the back of the vessel to carry enough fuel for three days' work. The tanks hold 42,000 cu. ft. (1,260 cu. m) of CNG at 3,000 psi (20,700 kPa). Fuel line pres- sure is stepped down to 125 psi (862 kPa) before entering the engine room, and supplied to the carburetors at a rate of 6 psi (41 kPa). Haushalter, who worked on the project from its inception, is proud of the suc- cess of the James C. Echols. "It isn't easy doing a world's first," he says. "There were plenty of challenges, but we worked through them and we now have a very reliable boat." Reliable use of alternate fuel proved especially beneficial when the diesel fuel supply ran low for a short period of time last winter: At that time, TRT's first-ever natural gas powered ferry was the only ferry moving passengers across the Elizabeth River. Circle 199 on Reader Service Card CNG: An Alternate Fuel While natural gas is not expected to replace diesel as the predominant fuel in commercial marine use, it lends itself well to specific applications where use of alternate fuel is encour- aged or required. In the U.S., CNG generally costs less than an equivalent amount of diesel fuel. It burns clean- er, with fewer particulates, hydrocar- bons, and nitrogen oxides. While the equipment needed to store, control, and monitor CNG exceeds diesel requirements, technology is available to ensure its safe use. Your ship is your business.
