Performance Simulation of Ship Propulsion System with Slow Speed Diesel Engine under Aggravated Conditions

The doctoral thesis Simulation of performance of the ship propulsion system with slow speed diesel engine under aggravated conditions has resulted from years-long research and development work in the field of mathematical and computer-aided simulation model for a ship propulsion diesel engine. Writing and publishing scientific papers and reports have contributed to guidelines for creating a computer-aided model using the software application MATLAB 7.0 – SIMULINK. In this way, the possibility of connecting with already formulated and accessible models for control system elements has been made as well as usage of numerical procedures for forming and optimising inlet and outlet numerical data. The model has been applied to the propulsion system of a tanker built in the Brodosplit shipyard, powered with the diesel engine MAN B&W 6S50MC. Enquiry into technical documentation and all testing that was essential for this paper were carried out in the Split diesel engine plant Tvornica dizelskih motora – Split during the testing of the engine at the test bed and during the ship’s trial trips. The model is applied in the analysis of static and dynamic operating conditions of a turbocharged slow- speed diesel propulsion engine with a fixed blade propeller. Special attention has been paid to examining the stability and availability under aggravated operating conditions such as load reduction in one of the cylinders or difficulties in scavenging and the turbocharging system. The analysis of the results has identified ultimate limits of affecting features and has defined safe propulsion conditions, in particular those related to the speed regulation and turbo charging systems.
