Abstrakt:

The Forth Replacement Crossing (FRC) is a EUR 2.2 B project to construct a 2.6 km cable stayed bridge together with associated network connections. The Firth of Forth, which the bridge crosses, is a navigable waterway with tankers, ferries and container vessels up to 45,000 tonnes displacement passing under the bridge. Marine risk and ship impact loads are important design considerations.

A quantitative marine collision risk assessment and cost-benefit analysis was carried out in accordance with the As Low As Reasonably Practical (ALARP) principle to determine the required impact resistances of the piers. Unique aspects of the methodology were the development of a semi- holistic model for collision probability and an explicit function for probability of collapse.
