Preferred solution, K12 - main report

Abstract

This report outlines the preferred solution for crossing of Bjørnafjorden for phase 5 of the E39 Bjørnafjorden project, performed by the AMC project group.

Current version of this report is the final report issued for milestone 9 of this contract. Focus for this final report is to document the analyses and design work done as basis for choosing the preferred alternative, and the evaluation done hereto.

The preferred alternative is outlined to be K12, which is an end-anchored floating bridge with 3 clusters of supplementary moorings to avoid the possibility for unacceptable resonance from parametric excitation as well as to reduce the effective buckling and span length and thereby reduce cost.
