Temple, D. and M. Collette. 2012. "Multi-Objective Hull Form Optimization to Compare Build cost and Lifetime Fuel Consumption." In Proceedings of  IMDC 2012. 2:391-403. Glasgow, Scotland: University of Strathcylde.

In today’s marine world there is an increased focus in reducing the lifetime ownership costs for vessels. The effort has been applied towards every stage of the ship’s life – from design through maintenance. However, most naval architecture practices for reducing lifetime ownership costs in the design phase focus mainly on reducing the fuel consumption of the ship. The focus on resistance alone may actually increase ownership costs, including those of initial production and through-life maintenance. These costs are often overlooked in the initial design stage owing to the difficulty of estimating them compared to ship resistance.
This paper explores the trade space between a vessel’s fuel consumption and her initial build cost. Using a variant of the multi-objective genetic algorithm optimizer NSGA-II, the optimizer was allowed to transform the hull form while tracking lifetime average resistance and a metric for production difficulty. The Pareto-optimal front for these two competing cost objectives was developed for a naval combatant based on the DTMB 5415 hull form and a container ship based on the KCS SIMMAN hull form in order to understand how the trade space varies with mission profile and vessel type. Using the Pareto-optimal front generated by the optimizer, hull-forms can be selected that minimize either of these components of total ownership cost in the most efficient way possible for the other. The trade spaces can then be used to increase the effectiveness and reduce the cost of the initial design.

In this paper a new metric for determining build complexity considering factors such as access for welding, bracketing, steps in plate thickness and related producibility concerns. The new metric is applied to the creation of stiffened panel structures. Using a multi-objective genetic algorithm the Pareto trade space between traditional cost estimates and the new complexity metrics is developed. By comparing designs along the Pareto front, the effect of reducing complexity has on estimated production cost is further explored. In general, it is shown that traditional costing methods and the new producibility metric are in competition and there is a large tradeoff. It is believed that this metric can be expanded beyond stiffened panels into all areas of the hull structure.
