The study concentrates on a fictitious rubble mound breakwater used to protect the marina situated near the entrance of the port of Le Havre, in France. A maximum failure probability is assigned and the structure should meet the requirements. Different failure modes and their relation to the overall failure of the structure are represented in a fault tree. Failure of the water retaining structure happens when the water enters the protected area uncontrolled. Both Ultimate Limit States (ULS) and Serviceability Limit States (SLS) are considered under present climate conditions, as well as utilizing basic assumptions for the future marine conditions in the study area. The set of acceptable geometries for the system is defined based on the probabilistic constraint of the maximum failure probability and an economic optimization of the total lifetime costs, namely the costs of construction and failure of the structure.
