Diesel electric marine propulsion

Caterpillar generators and Westinghouse propulsion motors on a research fishing vessel

[@shawnbeerens4292]

Those are big elecreic motor setups!! Do they use dc because its easier to vary the motor speed?

[@steamman9193]

Yes DC is much more controllable for varying speed. There are other factors at play and you can do AC but for this application DC works better.

Cool, are you now sailing on a research vessel instead of containers

[@steamman9193]

Yes, just a short rotation on one. Didn’t want to travel overseas with covid restrictions.
