Abstract:

Effectiveness of naval shipyard overhauls is examined by relating the amount of repair and alteration work done in overhaul to ship material condition during the full period after overhaul. The relationships are determined statistically through a model which also includes the effects of other influences on material condition, particularly personnel and operating tempo. The study focuses primarily on repair work. It considers overhauls from FY 72 through FY 78, and for each of the FF-1052, DDG-2, and SSN-637 classes separately. In addition to examining the relationships between overhaul work and post overhaul material condition at the whole ship level, the study also examined these relationships for a number of ship systems. These systems are representative of the hull, mechanical and electrical systems generally. Material condition is measured by indicators from a number of sources. These sources include CASREPs, 3-M maintenance reports, UNITREP status, PEB examinations, and INSURV inspections. Limited use is also made of ship engineering logs. The single measure most emphasized is CASREP maintenance downtime. Author
