Research for Ship Maintenance

In this report, we examine the question of where the Navy's depot maintenance should be done. In FY 1992, the Department of the Navy spent $7.5 billion on depot maintenance, and most of that work was done at naval depots. Now that the workload is declining, however, the Department of the Navy and the Department of Defense are looking at the possibility of doing more of that work at private facilities.

The Department of Defense Appropriations Act of 1992 directed the Secretary of the Navy to study 'the costs of improving the Port of Haifa, Israel, and facilities in the immediate vicinity, to accommodate the full complement of services required for the maintenance, repair and associated tasks needed to support a carrier battle group.' The Secretary of the Navy tasked the Center for Naval Analyses to conduct the study. He asked that we address the needs of rotationally deployed naval forces in the U.S. Sixth Fleet. We did not address homeporting in Haifa. We assumed that the Navy would continue to maintain self-sufficiency of its deployed forces. Providing support to visiting ships can be thought of in two dimensions: (1) the level of services each ship will demand; and (2) the number of ships that will simultaneously make such demands. Even more complicating is the fact that different types of ships request different levels and types of service. To cover the range of needs the port of Haifa may encounter in the future, we examined different levels of demand and support. Our analysis examines requirements generated by five notional task groups, comprising various numbers and types of ships. For each task group, we also analyze different degrees of support and provide assessments of the marginal benefits of a range of investment levels. This paper presents our research on logistics issues relevant to ship visits to Haifa and support of fleet operations in the general vicinity of Israel. We also address the flow

We have published the results of our study in separate documents -- one each on harbor services, ship maintenance, and logistics support, plus a summary report. This research memorandum addresses the harbor services portion of the support provided to ships visiting Haifa. Our work was supported by the Naval Facilities Engineering Command, Atlantic Division.

Measurement of ship material condition may be based on equipment downtime, using either Casualty Reports (CASREPs) or ship engineering logs. Measurements based on these sources are compared, and the correlation between them is studied. Data for this statistical analysis represents 13 hull, mechanical, or electrical ship systems from FF-1052 class ships.
