Marine Propulsion Engines 2


The aim of the manufacturers of marine engines is the auto-diagnosis of the drive system with a plethora of sensors, microprocessors, knowledge, experience and discipline and the timely maintenance according to the direct ON-LINE instructions of the manufacturer. Knowledge of the modern drives of the main engine manufacturers, Wartsila, Burmeister & Wain, Caterpillar, etc., is necessary and their particularities.

Replacement of mechanical transmissions with electric beam. For electric drives, 4-stroke diesel engines, usually gas turbines, can also be used. For single-shaft mechanical single-shaft drives and large screws, slow two- or four-stroke engines for all other fast four-stroke engines. Criteria for engine and propulsor selection: fuel consumption, required fuel quality, engine speed, matching characteristics, maintenance costs, reliability and operability of the complete drive system, maneuverability, frequency of operation at different loads. Diesel electric drive systems and their application, maintenance. Optimization of the ship's plant.


Power driven engines: steam turbines, gas turbines; diesel engines: two-stroke, four-stroke. Generating electricity: synchronous generators, excitation of synchronous generators.

• Power plant systems: auxiliary machines, main machine

• Propulsion of the ship

• Electric propulsion components: synchronous motors, asynchronous motors, static converters, frequency regulators, etc.

Drives with various propulsion fuels, heavy fuel, light diesel, gas (LNG). Hybrid drives and alternative drive sources.
