The background for this study is the Great Belt Fixed Link Project, Denmark, which includes the construction of a large span suspension bridge crossing an international shipping route. As part of a comprehensive vessel collision study for the proposed bridge, analyses of vessel collisions to bridge piers at several U.S. and Canadian bridges have been carried out. By use of empirical rules for navigation span opening requirements derived from ship domain theory, it has been possible to use vessel collision experience from bridges with different span openings, vessel traffic flow, navigational conditions, and environmental conditions. The results, achieved through the analyses of existing bridges, support the use of the empirical rules in the derived form to estimate the minimum span opening for the East Bridge. The results confirmed the need for a large span as found by computer-based maneuvering simulations. The empirical rules are considered to be useful tools, which could be applied to a first-step estimation of the minimum navigation span opening of bridges and also as part of the analysis of navigational safety at existing bridges. The study included development of another method to evaluate the relationship between bridge design and ship traffic by estimation of the number of close encounters in the vicinity of the bridge on the basis of the assumption of Poisson-distributed vessel arrival.
