As was noted by others, it depends on what machinery and fuel type each ship was designed with as built. The AmShip footers are different, as the Pielstick engines were designed for IFO180 blended fuel oil. The BayShip footers (mostly) had EMD engines, which were pure MDO. With IFO and HFO (Residual Fuels), there are separate Storage, Settling, and Service (Day) Tanks. Sometimes the Settling Tank is omitted, but for as long as I've been at sea, they have been mandatory in new construction.
Some recent ships (built after year 2000) have separate Low Sulfur tanks, for when the vessel is steaming in Emission Control Areas, but that has gone out of favor and many ships now only bunker low sulfur fuel oil exclusively. I believe the lakes has transitioned to purely diesel oil (MDO) now.
I recall the Columbia Star and Oglebay Norton consumed around 14,000 gallons per day. Obviously dependent on weather, loaded/ballast, and who was the Captain.
Only the lakes measures fuel consumption in gallons. Elsewhere it is Metric Tons.
A good example is the above 14,000 gallons per day (44.54 MT, roughly). The ship I am now Chief of (ocean going...a saltie, as you say) is of similar cargo capacity, but consumes 18-20 MT of MDO per day. Single engine, slow speed MAN. Other vessels in the fleet are newer and average 15 MT per day. When we used to burn DMA (HFO380), it was a few MT less per day...heavy oil is more efficient. Point is, the EMD engines are a bit long in the tooth (and were never really suited to be a good/efficient marine engine anyway).
