Ha, sweet. Can you imagine the HP just the get that thing turning?
I wonder how much it weighs....I'm thinking at least 26 tons. Althought it looks like aluminum. I can't imagine aluminum holding up to the torque, though.... |
What the hell is that off? Boat?
They should step it up to a giagantic rotory! It could be half the size |

Yup, Sulzer slow speed engine. See the 100 rpm on the sign? Engine like that is directly coupled to the propeller.

I've seen these pics a lot, but the never cease to amaze me!

I thought they didnt do that anymore? Dont most modern ship engines feed a generator which turn the prop to avoid damage to the engine if the prop gets fouled or hit or something? |

No one cares about vibration on a commercial merchant ship (within reason), hey, us seamen are second class citizens! It is more efficient to direct connect a slow speed engine to the propeller. Medium speed engines will use a reduction gear to give the most efficient speed for the propeller design used. Going astern (in reverse) can be accomplished through the use of either a controllable-reversible pitch propeller, or having the engines reverse directly (done by having the camshafts shift position). High speed engines are not used on large ships, the disadvantages outweigh any advantages. As for hitting anything, if the mates know what they are doing you should never go near anything. However, even with electronic navigation (GPS, electronic charts etc) humans make mistakes (especially mates!). And sometimes there are hazards that you can't see below the water (like subs). Bottom line, no matter what is turning the prop, if you hit something with it you are going to have a big repair bill. |
How much diesel does it use? I'm assuming they would measure consumption in gallons (hundreds of gallons?) per hour.
