Devil in the Details
Every engineer from MMA knows a tiny thing can stop a big ship. Keeping a watchful eye and maintaining critical systems are taught in a variety of ways, but none more so than hands-on shipboard training.
Take the example Chief Engineer Sandy Cameron ’84 shared as preparations were made for this year’s training cruise — a broken, fingernail-sized chip (see bottom left in background photo) from a capacitor module’s insulating board that separates two electrical conducting panels, which route 690+ volts each as part of the ship’s electric propulsion motor drive system.
The broken chip was discovered during inspection and the module replaced, thereby preventing what could have been a catastrophic electrical arc that could halt the ship in the water.
“In the engine room, you have fuel, mechanical and electrical systems—all requiring a degree of condition that has to be spot-on in order to keep it running and everyone safe,” Cameron says. “You can’t learn that in the classroom. You have to experience it, and that is why the students are here.”
