Prime Mover

The prime mover onboard a vessel are the fuel-driven source of mechanical energy, the main engine(s) that deliver the the power to propel the vessel through the water. The concept of prime mover can become somewhat convoluted with diesel-electric propulsion arrangements, where multiple engines may be used to generate electricity for electric motors or azimuthing podded propulsion. These generator sets are considered the prime movers.
