VTI has been commissioned by the Swedish Maritime Administration (SMA) to analyze the impact of the International Maritime Organization’s (IMO) more stringent sulfur regulations, which will enter into force in 2015 in the Sulphur Emission Control Area (SECA) which includes North Sea, Baltic Sea and the English Channel. A similar analysis was conducted in 2009, but an update has been justified (due to that) since there is new information available and that the implementation is approaching. The current analysis is based on three investigation scenarios, selected by the SMA. These scenarios are simulated in the national freight model Samgods (test version of the new Samgods model), which is a cost minimizing model. An earlier version of Samgods was used in the analysis in 2009.
