Sažetak
Basic characteristics of an efficient transportation are safety, cost effectiveness and friendliness with the environment. According to various environmental impact assessments, ocean-going vessels, as the most important part of maritime transportation industry, will have increasing influence on the global ecosystem in the near future. In the modern approach to ship-design the problems related to energy efficiency and environmental protection must not be left aside. Fortunately, in majority of the cases, they are related with the ship economic efficiency in a manner that does not require much compromise and measures undertaken are mainly in the same direction. Improving the energy efficiency of the ship means increasing profits and reducing the adverse impact on the environment. From the navigational and marine hydro-dynamical point of view, the accurate calculation or at least reliable estimation of attainable ship speed at actual sea is essential both from economic and environmental aspects. Reliable ship speed-loss estimation under real environmental conditions allows a more accurate prediction of the power increase and fuel consumption as well as gas emissions from ships. On the other hand, technological enhancements like improved hull designs as well as improvement in power and propulsion systems could potentially reduce CO2 emission up to 35%. These measures could effectively be combined with several other operational measures, such as optimal weather routing and voyage planning for ships, in order to ensure that fuel consumption and CO2 emissions from ships are minimized on every voyage. Appropriate strategy for greener shipping based on aforementioned approaches is proposed in this paper.
