CVN 68 Class Displacement Concerns; Dealing with the Differences between the Modeled and Actual Displacements

摘要

The purpose of this thesis is to determine whether or not CVN 68 class aircraft carriers are actually exceeding displacement limits based on NAVSEA projections. The NAVSEA projections are based on commissioning displacement plus any weight added to the ship during subsequent availabilities. The NAVSEA data was augmented with historic displacement values collected from all commissioned CVN 68 class aircraft carriers. Analysis reveals that the NAVSEA projections are predicting the carrier's displacement at approximately 4,500LT heavier than what is being reported by the ships. The result is a recommendation to conduct an Actual Operating Conditions (AOC) Displacement Check in order to update the NAVSEA displacement projections. By doing so, maintenance associated with weight removal will be minimized, a potential cost saving will be seen, and restrictions placed on ship maintainers will be reduced because a realistic operating condition will be known.
