The general structural layout is usually defined during the preliminary design. An optimization tool at this stage featuring flexibility, modeling speed and user-friendliness may provide precious help to designers. At this stage, few parameters/dimensions have been fixed and standard finite element modeling is often unusable, particularly for design offices and small and medium-sized shipyards. The LBR5 package performs early design least cost optimization. The software contains a module to assesses the construction cost, a module to analyses the considered structure, and the mathematical optimizer code. The paper contains a detailed presentation of the optimization of a medium capacity LNG ship including a sensitivity analysis on frame/stiffener spacing. This industrial optimization example shows that 5-9% of the construction cost of the hull manufacturing can be saved by performing scantling optimization at the preliminary design stage.
