Here's a couple. I won't have a lot of them as I worked entirely with one company with 3 ships. Mobil wasn't exactly a small company, but its U.S. flag west coast operation was.
Here's the first ship I worked on after Ft. Schuyler. Even in 1980 the Mobiloil was an old ship (built 1958), there weren't a lot of two house tankers left. I preferred the older ships where tanker mates carried a rag (to test if cargo was coming in or going out) and a signal mirror (to see the bottom of the tank during daytime) in their pockets, I detested working in an indoors cargo control room. I never completely trusted a valve was open or close if I didn't turn it myself.
The Mobiloil ran aground (steering gear failure) in the Columbia River in '83 and was scrapped. For me, classic case of not on my watch. I was on the 8 to 12 and it happened at 0002 (a pin dropped out of the steering linkage and we were stuck with rudder hard over and got intimate with Warrior Rock). Mobil replaced it with a laid up sister ship, the Arco Endeavour. Mobil re-named it the Syosset, being from Long Island, I was the only guy aboard who knew how to pronounce it.
