The maintenance of an aircraft carriers tanks and voids has a direct impact on ship operability and service life. The scheduling of inspections and repair work for these tanks and voids poses a significant problem for the carrier maintenance community. This thesis contributes to refining strategy in the repair planning process by providing the framework for building comprehensive tank and void database files. To demonstrate this, repair history files are constructed for USS John F. Kennedy CV 67 and USS Enterprise CVN 65. These files consolidate tank and void repair documentation from the myriad of carrier maintenance agencies and comprise the most complete database for these ships. A simliar database can be developed for all the carriers by duplicating this effort. A life cycle analysis of the data reveals that paint coating failure rates are more srmilar among tanks and voids on the same ship rather than among tanks of the same flinctional type. A case study for CV-67 examines model accuracy and predicts the expected number of coating failures at a filture maintenance period. The lessons learned in this thesis directly supports a follow on study of the JP-5 tanks on the Nimitz class aircraft carriers.
