Abstract: The thesis wants to give a brief to the effect of the EEDI and application of other indexes than EEDI. But the most important part was to analyze the effect on ship design and hydrodynamics of ship. All the types of ship that is appear in the analysis has shown almost similar pattern of curves.
How EEDI will give impact on the ship design parameters, For all the three sorts of vessels, it are often said that, if the vessel is to be designed for slow speed, it is better to have small length, breadth, draft and therefore the prismatic coefficient (Cp) for all speeds, as EEDIreference - EEDIattined value decreases with the increase of these parameters. On the opposite hand, it’s better to extend L/B and B/T at slow speed but, decrease at high speed. This means, the present EEDI formula will influence the designer and ship owner to build small ships in low speed range.
Finally we find the result and we can say that, influence of speed and length has the highest impact on EEDI, then the beam. Draft and prismatic coefficient does not have very high effects. So, it is satisfied from this viewpoint, if a maker needs to change the value of EEDI for a particular ship, he should look in to the length and speed first, then width, draft and the prismatic coefficient.
