Deep in the engine room of the SS James M. Schoonmaker lives this unobtrusive diesel generator. It’s a US Motors model D50D 50KW set powered by a 529 cubic inch Hercules DXRC indirect-injected diesel. The generator makes 50 kilowatts of DC power (400 amps at 125 volts) and powers the 6.5-ton deck hatch crane, as well as a DC-to-AC motor generator. The radiator may seem strange to you, given that most marine installations involve using raw water cooling (with or without heat exchangers). This generator was not designed to run for long periods and the radiator setup reduced installation costs. Given the engine room is well ventilated because of the nearby boilers and steam turbines, it’s not likely running it for an extended period would be much of an issue anyway.
