Les, I don't have much information. A few days ago I was looking at a Dutch tanker site on the internet, and I remembered looking at the 2 big tankers. go to this site and you might find more information.
That's a great site for any Shell men. I only ever sailed on one tanker in all my years. That was I.D.Sinclair of CP Ships when it was new from NKK at Tsu. in 1974. Didn't go much on it! 4 months and never left the ship, I liked proper ships with 'sticks and strings'
I sailed on an equal amount of cargo ships and tankers and one cruise ship, and I enjoyed my time in all of them. I was never on a crude oil tanker (i don't think that I would of liked it), I was on chemical, clean oil and gas tankers, and they mainly went to nice places.
