Derivation of the U.S. Navy Ship Design Speed-Power Margin Policy
This paper describes the analyses used in deriving data which are applicable to formulation of the U.S. Navy's speed-power margin policy. Corrections made to the powering predictions and trials data for the ships in the data base, in order to achieve equitable comparisons of predicted powering performance and powering performance acutally measured during full-scale trials, are described; the power margins derived from these comparisons are presented. In addition, a statistical analysis of this newly derived power margin data is described and the results are presented. It is shown that the statistically derived margin values provide an appropriate basis for a speed-power margin policy and that small changes to the current interim NAVSEC speed-power margin policy may be desirable
