The stability of slow speed diesel engines under conditions of considerable destabilizing impact

Vessels are affected by a wide range of operational factors that having an impact on the ship's power plant. Such operational factors include increased wear and roughness of the propeller, depth of the fairway, draft of the ship, wind conditions, trawl resistance, ice conditions, seawater density, torsional oscillations of the propeller shaft, exhaustion of the service hours of the power plant elements, etc. The process of controlling the main engine of the power plant should ensure the safe operation of the vessel, especially when operating at rated power in the event that significant changes in load on the screw side occur. The intensity of the change in load can lead to serious negative consequences, especially when the main power plant is operating at maximum power, for example, a critical increase in the speed of rotation of the diesel crankshaft, which, when the protection is activated, leads to engine shutdown.
