The Continuation of a Damage Control Stability Module for the FFG-7.
Abstract
The damage control stability module for FFG-7 class frigates is an interactive computer program which performs the load accounting, calculates hydrostatic and stability parameters, and provides the operator with recommendations necessary to counter the flooding threat to the stability of the ship. Continuing development of this program was undertaken to provide more accurate prediction of the ship's final flooded state throughout the range of trim expected as a result of damage. An investigation of the effect of trim on the hydrostatic and stability parameters which define the state of the ship was carried out ot determine the effect of trim-dependent variances of these parameters on the accuracy of the Stability Module. The input data considered was limited to the intact liquid load accounting of the ship. The effects of trim on the pertinent hydrostatic and stability parameters were found to vary with trim, resulting in variances of these quantities over conventional methods of calculation. Results of the sensitivity analysis led to the conclusion that the module is relatively insensitive to reasonable inaccuracies in the input liquid load accounting. The data base was extended to include all watertight subdivisions below the second deck.
