I'm not even going to attempt to show my insignificance in Navy speak. Okay, does it have something to do with propelling the boat ??
Outboard motors and oars propel BOATS. And you can pick up BOATS and put them on SHIPS. Buncha boots around here...
They told us that if the turbine came apart, the blades would blow through the housing and it the blade didn't get you, when it hit the 1200 pound steam line that would. I believed them.
Weirdly enough, the turbine casings are built to withstand that kind of accident. The blades weigh less that a pound each. The casings would make a good tank shell.
I'm trying to learn about Ships. Now I understand why Ships are Ships and boats aren't ! The Complexity of these things is brain numbing.
And there's almost no moving parts on that boiler. Try a 250 KW Ship's Service Turbo Generator. About the size of a minivan. When one of the Hawaiian Islands lost their power plant an LHA tied up to the pier and supplied the entire island with electricity.
