Within the 91-meter (300 ft.),double-hulled vessel are some 6,200 cubicmeters (39,000 U.S. barrels) of fuel valued atroughly $3.3 million (U.S.). That’s a lot of fuel,and some ships will consume every bit of itbefore journeying out into the broad Atlantic.Fast, reliable, and efficient pumping is a mustto move that much fuel and to avoid steepdemurrage rates of $2,500 per hour if a ship isdelayed. With an excellent track record, theGCS 238 pumps a whopping 1.2 million litersof fuel per hour (324,000 gph). Aboard thisocean-certified barge are two Byron Jacksoncentrifugal pumps each powered by its ownJohn Deere PowerTech 6125H industrialengine. The Environmental Protection Agencyhas certified the John Deere PowerTech 12.5Lindustrial engines for use in marine auxiliarycommercial applications (see note at right).Lots of forethought. Barge owners AlexGellatly and Mario Criscione, who own andoperate Gellatly & Criscione Services Corp.out of New Jersey and New York, chose theJohn Deere engines for the new GCS 238 afterextensive research and serious consideration ofall the competitive engines on the market. “Ichecked with several other people who ranJohn Deere engines concerning reliability, andequally important, the network of dealers in theNortheast,” says Gellatly. “I received nothingbut great reviews about the engines. And loand behold, John Deere has a vast network oftechnicians in the field to service them.”Gellatly says the 317-kW (425 hp) enginesoffer an ample reserve of horsepower needed tomaintain a constant rpm, which is so crucial in10 PowerSourcekeeping the refueling process running smoothly.“We needed a 15 to 20 percent reserve shouldthere be backpressure or restriction in the line,”explains Gellatly. “We have the reserve powerso it doesn’t bog down.”Electricity. In addition to the PowerTech6125H engines, the GCS 238 is fitted with twogenerator sets powered by PowerTech 4045Tmarine engines that deliver 60-kW of continuoushorsepower. The gen-sets each take turnssupplying the electrical needs to the barge,including the crew’s living quarters, the motordrivenhydraulics, air compressor, navigationequipment, blowers, and mechanical tools.Gellatly says each gen-set, alone, provides acontinuous supply of power that’s more thanadequate to run all of the barge’s electricalfunctions nonstop throughout the year.“Every one of my employees has nothingbut great reviews on the John Deere engines,”relates Gellatly. “What we need are reliablepumps and pump engines, and John Deere fitour package perfectly. The engines are smoothand reliable. We haven’t had one incident withthe John Deere engine where it delayed us orcaused us to find an alternate barge.”Gellatly & Criscione continues to upgradeits fleet with double-hulled vessels with morecapacity and reliability. And Gellatly says healready knows what type of power will beaboard these new vessels: John Deere. “Theproof is in the pudding,” he says. “We lovethem.”Engines: John Deere PowerTech 6125H — a317-kW (425 hp), 6-cylinder, 12.5L, air-to-airaftercooled diesel engine.

Several models of John Deereindustrial engines are now approved formarine auxiliary applications. Thesemodels include the 187-kW (250 hp)PowerTech 6068H, the 242-kW(325 hp) 6081H, the 317-kW (425 hp)6125H, and the 392-kW (525 hp)6125H. A marine auxiliary engine isdefined in 40 CFR Part 94 and clarifiedin EPA documents EPA420-R-05-008,“Test Procedures for Highway andNonroad Engines and Omnibus TechnicalAmendments, Technical SupportDocument and Summary and Analysisof Comments” and CSID-06-012“Portable Auxiliary Marine Engines –Interpretation of Installed”. In summary,an engine is considered a marine auxiliaryengine if (1) it is tied to the ship’sfuel, cooling, or exhaust systems, or (2)it is mounted on the vessel in such away that requires significant effort toremove it. For example, if a portableengine is designed with a quick-connectaccess to the onboard fuel supply orwith other hardware that allows theengine to tie into the vessel’s coolingor exhaust systems, EPA will considersuch engine installed. Even though it is“portable,” such an engine generallycannot operate without the fueling orother systems available on the vessel.In other words, it cannot be operatedonce it is removed from the vessel. If theinstallation meets the marine auxiliarycriteria, then the engine can be certifiedas a marine auxiliary engine.
