ABSTRACT
This paper will focus on the potential ship allision risk for a proposed fixed crossing of the Nordfjord on the West Coast of Norway, and the effects of various riskreducing measures. The proposed project consists of a floating bridge with a relatively low clearance above the sea and a separate bascule bridge to allow for the passage of larger vessels with a height of more than 18 m. The fjord has a relatively low amount of ship traffic, but during the summer season, the fjord is frequented by some of the largest cruise ships in the world, with the potential to cause the full collapse of the floating bridge. A list of potential risk-reducing measures are discussed to find the measures with the potentially best benefits. An alternative solution with a traffic separation scheme to reduce the risk to the bridge is also investigated in this paper.
