STRUCTURAL PERFORMANCE NORMS IN SHIP DESIGN

Based on the belief that midship section structural characteristics have a dominant effect on hull steel weights and construction costs, the use of high-strength steels is considered in some detail using the Mariner for illustration. Extending an earlier study, the design decisions addressed include the optimum interface locations between steels, effects of labor rate and overhead allowance, framing system choice, frame spacing, steel price and fabrication cost variations, hull stiffness, and the location of the strength deck. A means of predicting the potential benefits of other materials, real and hypothetical, is suggested. Although the design conclusions drawn apply strictly only to the subject ship, it is shown that a quantitative basis for them is readily available for any design by means of a computer-aided design assistance. In addition, a major modification to the midship section preliminary design computer program discussed in a previous paper and used in the studies is here described briefly.
