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.
