Unusual sight, passengers on a Great Lakes freighter. (Please read details below - Bitte Details unten lesen.)

Erst in der Vergroesserung gut zu sehen. Ist das wirklich mit Dampfantrieb?

Hier ist mal Genaueres ueber den Antrieb:

2x MaK M43C 6-Cylinder Inline Four-Stroke Diesel Engines Rated at 8,560 b.h.p each.
Was das alles auf deutsch bedeutet, kann ich leider nicht sagen.

ich auch nicht!
Aber Steamship steht dran . Und der Schornstein zeigt viel Dampf.

Joerg, die Firma, der das Schiff gehoert, heisst "Steamship Company", der Frachter ist mit Diesel angetrieben.

Die Aufschrift "steamship" hat mich auch auf eine falsche Faehrte gelockt.

Trotz der maechtigen Rauchwolke ist es in der Tat mit Dieselantrieb, wie Doerthe es beschreibt:

Es sind demnach zwei 6-Zylinder-Viertakt-Motoren (inline) mit je 8.560 break horse power (Bruttoleistung), der Hersteller ist Mak = Maschinenfabrik Kiel!

The passengers are there to show the scale of the boat. ;-)
This is the largest boat on the Great Lakes. It is not a steamship; that is the name of the company that owns it. BHP is "boiler horse power", which is used to rate the power of ship engines in the USA. I believe there is a typo in the description of the boat. 8560 BHP converts to 84000 kW per engine, but the engine manufacturer (Caterpillar) says this engine produces only 6000 - 9450 kW. So I think the actual power of each of the two Diesel engines is probably 8560 kW.

Thanks very much for your input, Ron.

Sorry Ron, the conversion of BHP (brake horse power) to KW is with multiplier 0.745699872!

These are not brake horse power, but boiler horse power. One boiler horsepower = 9.8125 kW. Also, I think the description incorrectly lists the power of the engines in BHP, but they are actually 8560 kW.

I'm reading this with interest. Thanks to both of you, Volker and Ron, for your contribution to this photo. Rarely do I meet anyone that has any interest in freighters, much less knows about engines moving these steel 'buckets' through the Great Lakes.

Agree with you that 1 boiler horse power is almost 1 kW, but boiler HP concernes to steam engines (boilers) only. As far as I understand Doerthe this ship is equipped with Diesel engines. So during my studies as a mechanical engineer we used to calculate with break horse powers for all types of motors.
But I dont mind to accept that the 2 motors in question do have 8560 kW each :-)

I believe you are correct, Volker. I became obsessed with boiler hp which confused my calculations. The smallest of this series of engines produces 6000 kW and the largest 9450 kW. Do you know the source of the large amount of steam in the exhaust?
