driven by both gas turbines and steam turbine(s). Heat recovery steam generators are fitted in the gas turbine exhaust lines and generated superheated steam (at approximately 30 bar) is led to a steam turbo-alternator. COGES completely change the properties of conventional propulsion system. Possible Efficiency Increasing of Ship Propulsion and Marine Power Plant with the System Combined of Marine Diesel Engine, Gas Turbine and Steam Turbine. By Marek Dzida.

A computational study on the performance and emission parameters mapping of a ship propulsion system, Proceedings of. In recent years, the Navy has used nuclear propulsion systems for its submarines and most aircraft carriers and conventional propulsion systems that rely on fossil fuel for its surface combatants and amphibious warfare ships. As the Navy looks to design an affordable force that is capable of meeting future security challenges, some of the assumptions and .
B. Exhaust Gas Turbine The outlet gas pressure of exhaust gas turbine Pto is given by Pto=Po+C(Gt/Gtm) 2 (5) Where Gtm and Gt are the gas flow rate of turbine at rated condition and at simulation calculating condition respectively, P0 is the atmospheric pressure and C is a constant. From the experimental data, it is found that C equals to File Size: KB. In recent years merchant marine propulsion has been dominated by the diesel engine (primarily the slow speed type) with fuel costs being the principal factor in favour of their selection. Fuel costs, however, constitute but one of the major constraints entering the design and operation of the marine power : L. N. Bakountouzis. Modeling and simulation of a hybrid ship power system. Abstract. Optimizing the performance of naval ship power systems requires integrated design and coordination of the respective subsystems (sources, converters, and loads). A significant challenge in the system-level integration is solving the Power Management Control Problem (PMCP).Cited by: 7. The differential equation derived using the ship surge dynamics is used for calculating the ship longitudinal movement and velocity. The developed tool was applied for the simulation of the propulsion plant of a merchant ship and the derived ship and propulsion plant operating parameters are presented.
