Dynamic Behaviour of Ship Propulsion Plant in Actual Seas

The paper consists of three main objectives: the mathematical model of diesel engine propulsion powerplant, hull-propeller interaction model including the effect of propeller emergence (propeller racing) and real-time dynamic behavior of the ship propulsion plant. One of the main advantages of the model is that it enables to investigate the dynamic behavior of diesel engine and speed control system at off-design and transient condition, allowing for real-time assessment of severity of propeller load demand fluctuation in order to improve model-based speed control schemes to ensure the safe operation of ship propulsion plant.
