ENVIRONMENTAL BENEFITS AND ENERGY EFFICIENCY ARISING FROM OPTIMIZATION OF VESSEL'S VOYAGE

Abstract

The number and size of vessels are increasing every day, and the maritime industry is
becoming one of the leading factors of global pollution. This paper will present the basic methods
and simulations which will show that significant environmental and energy efficiency benefits can
be achieved by optimizing the vessel’s route. A detailed description of the reduction of harmful
gases emission, which is resulting from the reduction of the ship's speed, will also be presented. In
addition to the presentation of the current existing results on this topic, the results obtained from
the analysis carried out on the ship machine and engine simulator from the Maritime Faculty in
Kotor, by the authors of the paper, will also be given. By optimization of the voyage, which comes
from more effective tasks performing at all organizational levels, the vessel is able to adjust its
speed in such a way to arrive at the port exactly on time for the berthing operations. This would
allow the vessel to reduce its speed, which would lead to the ultimate goal of minimizing air
pollution by reducing the emission of harmful gases from vessels.
