I have some history with ships, although sadly no pictures. In 1992 I left university as a graduate in chemistry and got a job developing engine oils for ships (and other large diesels like trains, power generators and such). Over the 10 years or so that I worked in this area I visited various ships, from relatively small coastal fishing and cargo ships to large container ships. A visit to the engine room was always a good day, even though it was not an especially pleasant place to spend the day - warm, smelly and under pressure to get finished and get out so the ship could sail.
One of the roles I had was to run field trials of development oil candidates in ships' engines. I had to find a suitable ship, go to its engine room, inspect the engine's cylinders and pistons by endoscope and have one or more pistons pulled out for me to analyse and rate, before being reassembled so the ship could leave. Often I had only a handful of hours, meaning I was handling a still-hot piston and the chief engineer was standing over me waiting to get it back in his engine for departure. I mainly worked on 4-stroke engines but did get to see some of the ultimate engines - the enormous 2-strokes. I still recall the first time I walked along one of the decks in the engine room past 4 turbochargers, each one larger than me. It makes you feel all Honey-I-Shrank-The-Kids when you see pistons, valves, con-rods, turbos etc at such a colossal scale.
