I am glad I don't have to change the oil in that thing!

Re: I'll show you mine, if you show me yours

I can't remember how much oil was needed but other specs, the cylinder bore is just under 38" and the stroke is just over 98".
Each cylinder displaces 111,143 cubic inches (1820 liters) and produces 7780 horsepower.
Total displacement comes out to 1,556,002 cubic inches (25,480 liters) for the fourteen cylinder version..
Some more facts on the 14 cylinder version:
Total engine weight: 2300 tons (The crankshaft alone weighs 300 tons.)
Length: 89 feet
Height: 44 feet
Maximum power: 108,920 hp at 102 rpm
Maximum torque: 5,608,312 lb/ft at 102rpm
Fuel consumption at maximum power is 0.278 lbs per hp per hour (Brake Specific Fuel Consumption). Fuel consumption at maximum economy is 0.260 lbs/hp/hour. At maximum economy the engine exceeds 50% thermal efficiency. That is, more than 50% of the energy in the fuel is converted to motion.
For comparison, most automotive and small aircraft engines have BSFC figures in the 0.40-0.60 lbs/hp/hr range and 25-30% thermal efficiency range.
Even at its most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour.

Re: I'll show you mine, if you show me yours

Bob,

Most of my sailing was with these engines, low speed diesels, 102 ~ 108 rpm range. I do have time with the odd medium speed diesels, 400~900 rpm. The slow speed is very fuel efficient. The 100,000+ hp slow speed engine only burned 60% more fuel than 43,000 hp in a bank of (7) 4.6 Mw medium speed diesels.

One of the seven


OK, show me yours, and remember, "Size doesn't matter"

Ferryman Water Cooled Diesel. This Generator is very light, weighing only 170 lbs and can produce 4.2 KW of continuous power.

Re: I'll Show You Mine, If You Show Me Yours

And you forgot all about the shaft generator typically hooked to these things.......last one I was around was 70megawatt!!

That would be about right if diesel-electric drive. On all the container ships I sailed on, all were direct drive. Cruise ships (I've never been on) break them down to 6 engines-generators, and the screws are driven by electric motors. The last drilling ship (rig) I was on had (7) 900 rpm generators, each could produce 4.6 Mw, used for hotel and drilling loads of around 1 Mw, and (6) 5,000 hp electric thrusters to hold position. In heavy weather I could burn 1,000 gallons of diesel (not bunker C) per hour just to hold position.

Re: I'll Show You Mine, If You Show Me Yours

Actually I was referring to the ships service generator. Last container ship I was on had a shaft gen, so while at sea the generators(s) could be offline and the propulsion engine would provide power for domestic as well as cargo loads.

Tell me more. Did you have to run at a given rpm for frequency regulation?

Re: I'll Show You Mine, If You Show Me Yours

Yep, the engine was governed at a constant speed, Off the top of my head I can't remember, 70-72 rpm or something like that.

Interesting. I'm guessing it wasn't a Yanmar.
