[en] Numerous real-world problems relating to ship design are characterized by many alternatives. Moreover in the scantling design, minimum production cost, minimum weight and maximum moment of inertia (stiffness) are conflicting objectives. Ship design is a complex endeavour requiring the successful coordination of many different disciplines, both technical and non-technical.
Basic design is the least defined stage of the ship design process and seeks to define the optimal
amidships section structure. For that purpose, recent improvements were made to the LBR-5 software to optimise the scantling of ship sections by considering production cost, weight and moment of inertia in the optimisation objective function. A real multi-criterion optimisation of a LNG carrier is conducted in this paper to illustrate the analysis process. Pareto frontiers are obtained and results highlight that LBR-5 is competitive software to optimise scantling of ships at very early design stage with management of critical problems studied normally at a later step of the design.
