Global warming has become a major concern in the last decade. The use of fuels with a high level of hydrocarbons, such as HFO (Heavy Fuel Oil) or DFO (Diesel Fuel Oil), consumed by the two or four-stroke engines integrated in ships, is one of the most studied environmental problems currently with regard to air pollution. This is due to Greenhouse Gases (GHG) emissions, such as CO2, NOX or SOX, or Volatile Organic Compounds (VOC) and PM (Particulate Matter, also called Particle Pollution) generated after the combustion process. This project will start from a previous data on a realistic scenario, where the possibility of the use of fuel consumption prediction systems is studied, taking into account the meteorological conditions of the sea and the wind, in order to draw the best route through the Mediterranean Sea, in terms of energy efficiency1. With the choice of the best route, GHG emission and the financial impact of transportation activities will be reduced. Within this framework, the objective of the project will be to develop a simple numerical model, taking into account several possible methods to achieve it, in order to simulate the same main engine with which the study explained above has been elaborated, comparing results with the intention to obtain similar values by dedicating less calculation time and in a simpler way. For this purpose, the current situation of our atmosphere, the main pollutants for which it is affected, the contribution of the ships to said pollution, the respective legislation on the polluting emissions of the ships and the limits stipulated by the IMO (International Maritime Organization) and the data of the main engine, together with the possible methods to obtain the consumption approximations will be explained and taken into account. With this emission factor, taking into account the ship's consumption prediction (based on sea conditions, giving special importance to waves and wind conditions), routes through the Mediterranean can be developed in order to reduce the consumption of the ship and the polluting emissions emitted, improving energy efficiency during navigation.
