Two types of analyses were performed using the HPAM computer program. First, baseline comparisons of typical and optimized hull surface management practices were developed for three representative ship types: a C4 break bulk ship, a C8 container ship, and a T8 tanker. Second, sensitivity analyses were performed in which the key ship design, operational, and economic parameters applicable to the baseline comparisons were varied individually to determine their relative contributions to the baseline results. These parametric sensitivity analyses serve two purposes: (1) to demonstrate that the optimum hull surface management practices identified by the HPAM program for a particular application do not vary over the uncertainty range of assumed data items; (2) to generalize the results obtained from the baseline comparisons to a broader spectrum of ship operating profiles.
