The stern section of a modern merchant ship, built with machinery and deckhouse aft, is the most labor and capital intensive portion of a ship's construction. This study analyzed the feasibility of standardizing the design and construction of this portion of a ship, for application to a wide variety of merchant ship types, as a means of improving commercial shipbuilding producibility. The concept permits one to obtain the advantages of multiple ship production (lower construction cost and shorter construction time), without restricting a prospective ship owner's flexibility in tailoring the overall vessel design to carry his particular cargo, and meet his requirements for payload capacity, cargo handling capabilities, and ship performance. The study found that the standardized stern concept is both technically sound and economically feasible, and that three basic stern units would be able to be used to satisfy 79% of all forecasted U.S. new building requirements to the end of the century. Moreover, with a production run of sixteen units, standardization of the stern unit would save a minimum of 7% of all the total cost of the stern. This savings could approach 20% if additional measures were taken to enhance producibility, such as the optimization of material flow patterns in individual yards and the use of more labor efficient materials and techniques.
