WOW! That was amazing! SOOOOmuch money involved. I'd like to have what they spend on tooling and machines needed to build that sucker. Casting, Machining, Metrology, assembly, (46) Dyno Test stands!! (not cheap ones either), painting, transporting. A very large fortune involved. I love working on stuff like that.

I've seen videos about these YUGE marine engines that workers actually can enter the engine below the pistons.....I'll try to find it. |

largest diesel I ever was around was on a Military Sealift Command (MSC) supply ship. turbos the size of cars. spare connecting rods hanging on the bulkhead were approximately 6' 2" tall. There were access panels to enter the crankcase. This ship had two engines.

Biggest one I ever watched being built was at a GM plant in SW Chicago area. It was a plant where they built diesel locomotives and the plant was one of my accounts when I worked for Xerox. Pistons the size of 5 gal. buckets....and noisy in an enclosed space.

I'm just absolutely amazed at the scale of that thing. Starting with the crankcase. The casting and machining is just mind-boggling. And how in the hell do you grind a crankshaft that big? |

My first experience with high speed diesels were the Sea Tek engines on a Ferretti boat. A 50 foot boat could do 65 mph through just about anything. The propellers were Rolla surface piercing and would throw a tail up when cruising at 45 mph. The engines were not the most powerful ones that they produced either but were the lower end of the power output. Really different to have diesel engines as the propulsion rather than gas and, maneuvering with them while in dock was cool. You would go to full throttle for the one in reverse and it would spool up and the sound was like the sound of a jet engine all the time feathering the forward throttle to stay in a spot and do a perfect 180. Turbo charger, intercooled about 850 hp and over 1400 ft lbs of torque out of a 6 cylinder engine. In the pic is the Rolla for the Arneson surface drive and the Sea Tek in the Ferretti were coupled to a similar drive. You would not want to get stuck behind the boat with the props in gear. https://www.google.com/search?q=rolla+surface+drive+props&client=firefox-b-1&tbm=isch&source=iu&ictx=1&fir=AOXUA6BJR7cyGM%253A%252C0RTdzFfMCZtTjM%252C_&vet=1&usg=AI4_-kSq-BiYhzysaacjcyMwcW0KDaXq_w&sa=X&ved=2ahUKEwignObxyp3hAhWlt1kKHXbyDUMQ9QEwBXoECAgQCg#imgrc=AOXUA6BJR7cyGM:It changed my whole view as slow diesels and I started to look more and more at diesels for boat design and even considered car. |
