| Abstract: |
The purpose of this paper is to investigate the main challenges and corresponding solutions for a floating bridge crossing Bjørnafjorden. The paper investigates challenges related to quantification of loads, design of permanent structures as well as temporary phases. The paper evaluates a curved bridge without mooring lines, but considerations are partly valid for a straight bridge anchored to the seabed as well. Both solutions have been used, but the length of the Bjørnafjorden crossing is significantly larger than previous bridges and thus more challenging. |
