The paper presents a comprehensive multi-objective hydrodynamic optimisation procedure and its application to the early design of a Floating LNG Terminal for improved seakeeping and wave attenuation characteristics on its lee side. Genetic Algorithms are used to find the Pareto optima designs followed by Multi-Objective Decision Making procedures to select the optimum design among them. The paper addresses the definition of the relevant optimisation problem and the setup and interface of relevant software tools, presents results of systematic studies with respect to the minimization of the motion responses and the wave elevation on the leeward side of the free-floating terminal and concludes with the analysis and critical review of the obtained results and their impact on the terminal design.
