    I saw some of that show.
    Did you see how big that shipyard was ? They do everything from actually making the steel from ore to the final ship.

    we just pulled an engine about half that size out of one of our dredges. we blew it up due to an oil failure somewhere. they aren't meant to be swapped out often. that one had been in the dredge for 40 years.

    I was on a cruise many years ago. I put a written request into the engineering and they took me on a tour of the ships engineering spaces. The engine room was absolutely incredible! Theirs was a bit smaller than the one pictured above-it was only 5 cylinders. Even so, the engine was 3 decks high. It turned so slowly that it looked like you could just reach out and stop the crank with your bare hand. The pistons were like 6' tall. They kept a spare one in the engine room. There was a overhead bridge crane for installing it! There were windows so that you could look through a porthole and see the crank spinning inside the engine! There were also doors that could be removed so a person could get INTO the crank case! You could feel each and every piston fire. The engine turned a constant rpm. I think that one was turning 150rpm. When a piston fired you could feel it through the entire ship. Consider the amount of mass in a ship that needs to resonate and you'll get an idea. They would speed the boat up or reverse it by changing the pitch of the props. The engine consumed some 55 gallons per mile of diesel fuel.

    More info:

    German design, Japanese labour, American paint...............

    The Wartsila NSD (Sulzer) RTA96-C two-stroke diesel engine is the most
    powerful and most efficient piston prime-mover in the world today.
    Bore - just under 3'2" (965mm).
    Stroke - just over 8'2" (2489mm).

    Available in 6 through 12 cylinder versions (all inline).
    Engine weight exceeds 2000 tons in the 12 cylinder version (the
    crankshaft alone exceeds 300 tons).

    Point of maximum continuous power is 89,640 HP (66,844kW) at 100RPM
    with the 12 cylinder version.
    Point of maximum fuel economy is 53,244 HP (37,704kW) at 90 RPM.

    The 12-cylinder engine exceeded 100,000 horsepower during overspeed
    testing (all of 101.5 RPM!) while under test at Japan's Diesel Union
    works (who built the first engines and from who these pictures are

    Fuel consumption at maximum power is 0.278 lbs/HP/hour (BSFC).
    Fuel consumption at maximum economy is 0.260 lbs/HP/hour.

    At maximum economy the Sulzer engine exceeds 50% thermal efficiency
    i.e. more than 50% of the fuel going into the engine is converted to
    For comparison, consider that automotive and small aircraft
    spark-ignition engines have British Standard Fuel Consumption figures iin
    the 0.40-0.60 lbs/HP/hour range and 25-30% thermal efficiency.

    Even at its most efficient power setting, the Sulzer 12 cylinder
    consumes nearly 1,660 gallons of heavy fuel oil an hour.

    Just for grins......

    100,000 hp @ 101.5 rpm = 5,172,413.7 ft-lbs of torque.

    Yes - 5.17 MILLION ft-lbs.
