A Comparison of CASREPs and Engineering Logs in Measuring Ship Material Condition,

Abstract

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. Based on the analysis in this report, there is clearly a substantial amount of equipment downtime which is not recorded in the CASREP system. Relatively higher and lower periods of equipment downtime, however, tend to be accurately captured by CASREP downtime. This implies that while CASREPs do not show all equipment problems, they may be accurate in showing relative equipment condition between different ships.
