On the possible increasing of efficiency of ship power plant with the system combined of marine diesel engine, gas turbine and steam turbine, at the main engine - steam turbine mode of cooperation This paper presents a concept of a ship combined high-power system consisted of main piston engine and associated with it: gas power turbine and steam turbine subsystems, which make use of energy contained in exhaust gas from main piston engine. The combined system consisted of a piston combustion engine and an associated with it steam turbine subsystem, was considered. An algorithm and results of calculations of the particular subsystems, i.e. of piston combustion engine and steam turbine, are presented. Assumptions and limitations taken for calculations, as well as comparison of values of some parameters of the system and results of experimental investigations available from the literature sources, are also given. The system's energy optimization was performed from the thermodynamic point of view only. Any technical - economical analyses were not carried out. Numerical calculations were performed for a Wärtsilä slow-speed diesel engine of 52 MW output power.

The dynamic behavior of a typical four-stroke, medium-speed, marine diesel engine driving a Controllable Pitch Propeller (CPP) is investigated during ship maneuvering including fast propeller pitch changes. A modular model has been developed in Simulink/Matlab for the simulation of the dynamics of ship propulsion. The developed model considers the ship propulsion system as a set of three main modules: the engine, the propeller and the ship hull. The developed ship propulsion dynamics model has been validated with a wide range of experimental data from a 500 kW test engine (MAN B&W 5L16/24), coupled to a four quadrant electric brake (AEG), installed at the test-bed of the Laboratory of Marine Engineering of the National Technical University of Athens (NTUA/LME). The model was then used for the investigation of marine diesel engine behavior during load changing including some extreme maneuvering case scenarios such as Crash Stop, Full Astern and Full Ahead maneuvers. The resulting ship propulsion model is a reduced order model, which can easily be used for detailed studies such as engine-control during fast transient loadings, with accuracy and small computational cost.
