Route optimisation based on AIS tracks in the Baltic Sea

Route optimisation based on AIS tracks

As a part of the FAMOS Odin research project, a route optimisation analysis was performed. SSPA presents the results of taking stored AIS tracks and optimising their route geometry as well as their speed to minimise fuel consumption, i.e. to minimise the shallow water resistance experienced by each ship. The results show key changes in traffic patterns, specifically fairway shortcuts that could be taken if there are no safety concerns. 

In the relatively shallow waters of the Baltic Sea, ships will have a higher fuel consumption compared to when sailing in, for example, the open waters of the Atlantic. This is due to higher resistance when the water depth under the keel is lower.

Three specific areas was analysed, east of Stockholm (area A), south of Bornholm (area B), and south of the area between Gotland and Hoburg (area C). This analys is an example of what can be achieved with route optimisation. Ship operators can save fuel, but extra care must be taken to make sure that optimising is done under the right constraints and with accurate models and data.

SSPA plans to continue to develop its existing route optimisation models and tools as part of future collaborative projects.
