Harbors play a pivotal role in global trade, serving as vital gateways for the transportation of goods. These essential coastal infrastructures are subjected to relentless forces which can jeopardize their functionality and safety. Safe working conditions are mandatory for the operability of all kinds of harbors. Particular attention must be paid in the case of terminals dedicated to Liquefied Natural Gas (LNG). This work presents 2D experimental campaign carried out to optimize, from a hydraulic point of view, the parapet wall of the new composite vertical breakwater that will be built to protect the new offshore LNG terminal located in in the North Adriatic Sea in the South-East of the Port of Ravenna (Italy). In particular, two types of parapets walls have been compared: one overhanging and one vertical. For each type of parapets, three different heights were evaluated for a total of six different configurations.
