This document reports the methods used and results obtained for the tasks established between SSPA and the FAMOS Odin project, as follows:Baseline analysis of traffic in the Baltic Sea, using collected AlS dataa.Analysis of safe Under-Keel Clearance (UKC) used in today’s trafficb.Analysis to which extent transport capacity is currently limited by UKCc.Calculation of the added fuel consumption caused by the squat effectSimulation of traffic based on improved bathymetry and UKC controla.Present energy efficient routing options with regards to distance, UKC and squatb.Calculate the benefits of optimized UKC for increased cargo capacityc.Use and test S-102 data as a basis for these analyses.This document reports as well the active partner’s budget outcomes, milestones and gains accomplished within the project timeframe.Analyses based on bathymetric and Automatic Identification System (AIS) data evidenced, for a chosen area of interest in the Baltic Sea, that tankers may be limited by UKC and as a result carry less cargo, which could amount to 1% more of the total cargo transported through the Baltic Sea, according to the model used. The results also show the linear relationship between the increase of speed and squat effect with the subsequent increase of water resistance and need of energy to propel the ship, signifying a direct increase in fuel consumption. Finally, the results emphasize certain regions of the Baltic Sea where routes could especially benefit from optimization for reduced fuel consumption, yet optimization results may depend on different route parameters prioritized by the mariner (e.g, speed vs. Estimated Time of Arrival (ETA)).Some recommendations for futures stages of this project include access to higher-fidelity depth data for Swedish waters to refine the studies described in this report, as well as the inclusion of a qualitative research component to investigate how UKC is perceived by the mariners or what reasons they may have for keeping a certain UKC or loading cargo to a certain weight.
