Those are some neat pics. I'm pretty sure the engine in the first picture is a smaller version, and not the biggest 14 cylinder available. My dad worked in shipping his whole life, so I spent a good deal of my childhood running around in the engine rooms of ships. At that time he worked for Carnival Cruise lines, and the cruise ships don't have engines quite that big, but pretty close. The Sulzer 14 cylinder engines are most recent ones. Sulzer had to dramatically increase the strength of the crankshaft to go from a 12 cylinder to a 14 cylinder engine.
I remember when I was a kid, the ship had some sort of problem on the crankshaft. My dad crawled into the crankcase of the engine and had the crew turn the engine over so he could crawl down where he needed to go. He's crazy. If for any reason they couldn't crank the engine again, he would have been stuck there.
