[QUOTE=Fraqrat;181345]The only thing I’ve ever been on close to that age was an old T2 the Marine Floridian. We had to retube a boiler after an explosion. I had never seen boilers where the tubes were horizontal running. That ship was a working museum still had hot bend pipe all over the engine room. I really wanted to be there when they fired it up so I could see how all of it worked.[/QUOTE]
I did work on both the MARINE FLORIDIAN and MARINE DUVAL when I was with ABS. They were regular customers when I ran/was the Galveston office. I also sailed on Matson’s old MAUNALEI, a C4 with the same sectional header boilers. Great design and simple. I believe that the design goes back to the late 1800s or more. Usually the superheater is on top, where the economizer sits on most D type boilers. I have also been onboard the OBRIEN when it is a steaming weekend and the fires are lit, generators and other auxiliaries running (all steam, very little electricity used on a Liberty), main engine rolling over very slowly. . . .
