The purpose of a crown wall on a rubble mound breakwater goes further than coastal protection; it also offers economic, ecological and social advantages. Few scientific studies are available on design and performance of crown walls and they often have limited accuracy. So a clear understanding of the applicability conditions for the methodology selection that better suits a safe and functional design is needed This article presents a review of the state of the art of studies on crown wall structures and a comparison between different methods available to provide the designers with an overview of the advantages and disadvantages offered by each one. As an example, the wave conditions in front of a liquefied gas terminal, off the coast of Baja California, México, are used, where calm conditions are needed to ensure the security of the vessel during docking and unloading; this means low transmission and null overtopping, which makes crown wall breakwater a good option.
