An optimum economic and technical hull design can be achieved using available structural analysis methods and probabilistic models for lifetime economy assessment. Advanced methods such as finite element modeling and sometimes also ultimate strength analysis are used in design. The objective is to build sufficiently strong ships using a minimum quantity of steel. High tensile steel is frequently used in high stress areas in order to save weight. Structural maintenance aspects are seldom considered during design. Yet this is the stage at which the basis for cost efficient maintenance is established. The design of the hulls girders, its structural components, coating and other protective systems will influence the need for future maintenance. The balance between design, structural redundancy, inspection and maintenance is discussed. Examples of structural reanalysis and maintenance economics are included.
