Existing bridges have sometimes to be evaluated considering ship impact. Using present codes for accidental would often lead to rehabilitation measures or two new structures might not be efficient regarding the rareness of the serious ship collision events to bridges. Therefore a method has been developed to determine ship collision forces as time-dependant action for the remaining lifetime of an existing bridge. This method is called remaining life expectancy concept, is based on the design concept of Eurocodes which is reliability based design procedure. It considers the principles of common maintenance strategies and allows the safe economic verification of existing bridges considering their experienced lifetime. The contribution explains the methodology of modern ship impact determination by combining a load model with a probabilistic model as it is used for design of new bridges. The adoption to remaining lifetime adapted dynamic impact force is shown.
