Résumé

[en] The main objective of a Naval Architect is to design most efficient ship with optimized hull to meet the challenges of a globalized market. So the final design has to achieve maximum speed, increase of cargo capacity, minimum fuel consumption and maximizing maneuverability, etc. Maritime industry is driven by such optimization process or researches for improved design to minimize the operational cost, fuel consumption and to maximize hydrodynamic performances at its service speed.
Whereas optimization of propulsion systems means to develop a propeller design for choosing engine power which gives the maximum propulsive efficiency without any noise and vibration problems. The transmission system connecting engine with propeller can be obtained once an optimized propeller design is realized for a suitable marine engine.
The objective of this master thesis is to design a container ship propulsion system with the selection of optimized propeller, main engine and other fundamental components.The type of propeller selected is a fixed pitch propeller as it is the most suitable one for the container ship since the service speed for the operational route is fixed. Engine will be selected by its power (MCR) to overcome ship resistance (including sea margin) accounting for other losses and shaft line will be design using classification society for its dimensioning and for the type of propeller.
The most important parameter required to begin propeller design is Resistance of ship at her design velocity which can be described as hydrodynamic force exerted by the fluid opposing its motion at that velocity. The final outcome of propeller design is to develop a propelling device capable of generating thrust sufficient enough to overcome this resistance.
Design of a propeller will be divided in three stages: preliminary design, detailed design and hydrodynamic analysis of the final propeller. On the first stage, main characteristics of propeller such as diameter, rotation rate, blade area ratio will be obtained using B Wageningen series data. Secondly, detailed design will be performed via lifting line theory. The objective of this stage is to find the propeller geometry for a radially varying distribution of the loading. While in final stage using CFD methods,propeller will be investigated in steady conditions in uniform flow(open water test) and unsteady condition in radially varying inlet velocity considering ship wake(self propulsion test).
