Ships burn one or more or a blend of several marine fuels: MGO -Marine Gas Oil A light fuel a truck might use except by law it must have a flash point above 150 degree F to be a marine fuel.MGO today costs $626 per long ton in the U S Gulf; don't know the Sarnia price. MDO- Marine Diesel- A darker heavier, cheaper fuel than MGO. Not used ashore as far as I know. Cost of MDO today $$591/per ton. IFO 180 Intermediate viscosity fuel used by many ships including Lakers, small ocean going and for ship generators on big vessels.Cost today $ 357 per ton. IFO 380- Heavy intermediate fuel almost like BUNKER C, Used by largest ocean and some Canadian Lakers.(Sometimes contains gritty catalytic fines that take a toll on cylinder wear) Cost $331/ton this morning. For rule of thumb calculate Lakers use .38 lbs per H.P. per hour for main engines of I-180. Thus a 14000 HP Footer might burn 57 tons per 24 hours actually underway at sea. Say half that rate in rivers. A 35000 tonner on Lakes would burn roughly half that rate per hour. Each will also consume about 800 hp of generator power or say 300 lbs per hour or 3.25 tons per 24 hours at sea and in port for generators- of either gas oil or MDO. In addition figure another 1500-2000 horses needing hay for each hour of discharge or say about another 6 or 7 tons of light fuel. You can probably do the rest of the arithmetic yourself. Good Luck,
