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.

Risk assessment of bridge collision – using Monte Carlo Simulation
The E39 road, connecting the Norwegian coastal cities of Kristiansand and Trondheim, includes eight ferry crossings. SSPA has been commissioned by the NPRA to conduct ship collision risk analyses and to compare different bridge and tunnel options from a navigational safety point of view.
Maritime spatial planning and ship routeing systems
The high and rapidly increasing demand for maritime space for different purposes, as well as the multiple pressures on coastal resources, requires an integrated planning and management approach. Rerouteing of shipping lanes and the introduction of new routing systems may be needed to ensure high maritime safety and sustainable co-existence of various marine activities. SSPA’s toolbox and experience assist planning and maritime authorities to prepare sustainable and efficient plans.
