Abstract
A method for evaluating the desirability of any proposed material in merchant ship structure has been developed. This method compares a ship designed of the new material with a similar steel ship. Comparison includes a life-cycle cost analysis and a quantified evaluation of non-economic factors. Formalized techniques for establishing the material data bank, selecting the steel ship design, developing and optimizing the new material design, and conducting the economic and non-economic comparisons are described. A sample calculation, using 5456 aluminum in a bulk ore carrier, is included to illustrate the method. (Author)
