The reason for this project is the need to expand the size of the canal, to allow larger vessels to safely use it. A choice is made for a vertical-type breakwater, i.e., a concrete caisson placed on top of a rubble mound foundation. The main goal of this thesis is to provide a preliminary probabilistic design of a cross-section of the new breakwater at the port of Genoa by applying a vine-copula model for the wave climate in a Monte-Carlo simulation.All possible regular vines were obtained by permuting the six equivalence classes for 5 nodes. 13 different copula types and all 480 possible 5-node regular vines were fitted on extreme wave data. The best vine-copula was selected based on the lowest AIC value. The performance of the vine-copula model was compared to that of an independent model.Offshore waves were transformed to onshore waves by applying SWAN. A MATLAB loop-function was made to automate this process. Prof. Goda's method was used for determining the wave-induced loads on the vertical breakwater. 10 failure modes were considered in total. A Monte-Carlo simulation was built in MATLAB. Using the Monte-Carlo simulation, several dozen designs were tested in an iterative matter to find an optimized design. The proposed preliminary cross-sectional design fulfilled all design criteria.
