An investigation into feasibility of a specialized allowance of critical spare parts for gas-turbine class ships

Abstract

The possibility of developing a 'suite' of critical engineering parts to be carried by one of a group of Gas-turbine ships when deployed together has been raised. Such ships are sufficiently uniform in their engineering plants to make such a 'suite' feasible. The end purpose would be to lessen the possibility of a loss of mission' engineering failure by having low demand parts in theater. The inherent question is that of the performance of both current allowance computation models and the operating procedures which support those models. To answer the questions, a test of the current COSAL model is compared with a similar test of a model more attuned to high levels of protection. Allowance computation procedures are explored, as are those of the related essentia^ty measuring systems. The author presents the results of this test, conclusions drawn therefrom, suggestions for possible action and recommendations for improvements in current reporting procedures.
