Propulsion performances study for a chemical tank

Résumé

The design of a propulsion system for each ship must take into consideration a large number of factors. Some important factors that will lead to obtaining an efficient propulsion system are: the integration of a large number of elements in a functional space, selection of suitable components, the efficiency assessment taking into account functional safety and comfort criteria for crew and passengers. Considering the factors listed above, the analysis and design of the propulsion system for a chemical tank was performed. To choose the optimal components, the propulsion performance for this ship was analysed using 4 different engines. The operation of the propeller behind the ship has an effect on both the structure of the ship and  the navigation conditions of the crew on board. Ttherefore, in the last part of the paper will be presented the effect of the operation of the propeller chosen for the chemical tank. In this sense, the surface forces induced by the propeller that appear in the stern vault will also be a center of interest in this work.
