This nuclear-powered merchant ship was supposed to revolutionize the shipping industry, but never did so. Many years ago I heard, from people who had actually sailed on the Savannah, that one of the problems with the ship was that a lot of countries would not permit a nuclear-powered vessel to come into their ports. However, another issue was the unexpectedly high cost of operating such a ship. The engineer officers who manned the engine room were required to be, not merely licensed marine engineers, but licensed nuclear engineers. Such engineers were much more highly trained, much more rare and consequently were paid much higher salaries than conventional marine engineers. Needless to say, the captain, licensed deck officers and unlicensed crew demanded proportionally higher salaries as well.
