Low carbon transport at sea: Ferries voyage optimization in the Adriatic

February 09, 2021

Energy efficiency or carbon intensity (defined as CO2 emissions per transport work, ed.) is a possible point of convergence between the International Maritime Organization (IMO) and EU regulations to cut GHG emissions and decarbonize shipping. Short term measures to increase energy efficiency and achieve carbon intensity savings include voyage optimization.

A new study led by the CMCC Foundation, realized in the framework of the Interreg Italy-Croatia , explores the potential of carbon intensity reduction through voyage optimization in short sea shipping.

To this purpose, the

"VISIR can compute optimal routes by suggesting a spatial diversion which leads to avoidance of rough sea and related ship speed loss", explains

The Adriatic Sea, which is routinely crossed by several ferry lanes joining ports in Italy with ports in Croatia, Montenegro, and Albania, was an interesting candidate domain for testing the role of route optimization on short sea shipping. It is relatively small and characterized by not too rough seas. Therefore, if optimization works there, it is scalable to bigger and stormier basins of the world ocean.

On top of that, ferries are quite relevant for emissions, as they account for about 10% of the CO2 emissions in the

Therefore, CMCC researchers tried to assess whether path optimization can play a role even for ferries in the Adriatic, what CO2 savings are potentially attainable, and how much ferries' carbon intensity can be decreased. In order to highlight the role of waves and sea currents in the optimization,

"Our results support the thesis that voyage optimization could be a viable operational measure for short-sea shipping to meet short-term targets for both absolute emission and carbon intensity reduction" comments Mannarini. "For a case study, we found out carbon intensity savings up to 11%, and this is an encouraging outcome towards both IMO and EU curbing targets. We now aim to produce more statistically significant estimations through a web tool we are going to develop in the frame of the Italy-Croatia Interreg project GUTTA."
