ESTIMATION OF THE EFFECTS OF A SHIP'S STEAMING ON THE FAILURE RATE OF ITS EQUIPMENT: AN APPLICATION OF ECONOMETRIC ANALYSIS
Published Date: February 1, 1981
Regression analysis is used to estimate the effects of a ship's steaming on the failure rate of its equipment, holding constant the effects of other factors such as a ship's class, fleet, time since overhaul, and point in the deployment cycle. Equipment failures are measured with data on 14,000 CASREPs for destroyer-type ships in 1970-75. It is widely thought that steaming would increase the number of equipment failures due to wearout. However, this report found that the failure rate of equipment seemed to decrease with steaming in the long run.
