New roueting system

Safer traffic in Kattegat and Skagerrak

Sweden and Denmark has jointly developed actions to improve the shipping traffic in Kattegat and Skagerrak to be safer and more environmentally friendly. SSPA has supported the Swedish Transport Agency with comparative consequence analyses for the proposed new routing systems. The IMO Maritime Safety Committee (MSC) has now approved the proposal for new ship routes that will be in place from July 1, 2020.

The traffic in Skagerrak and Kattegat is extensive, not least because traffic to the Baltic Sea passes through the area. Every year, about 60,000 vessels travel to Kattegat, most of them on their way to and from the Baltic Sea. In Kattegat, there is also extensive ferry traffic between Sweden and Denmark and leisure boat traffic, especially summer time. 

The major change in the new routing systems is a number of new Traffic Separation Schemes (TSS), a new Deep-Water route, and a separate route for ships in transit to the Sound. Separating traffic to the Sound from traffic to the Great Belt into different routes and separation of north- and southbound traffic by TSS will contribute to improved navigational safety. SSPA has calculated that the total fuel consumption for transit traffic will be reduced by approximately 1% by introduction of the new routeing systems.

- In order to ensure high maritime safety and sustainable co-existence of various marine activities, re-routing of shipping lanes and introduction of new routing systems may need to be implemented. SSPA has experience in assisting maritime authorities to prepare sustainable and efficient plans, says Björn Forsman, Project Manager at SSPA.
