RELIABILITY PREDICTION FOR A DEEP SUBMERGENCE RESCUE VEHICLE; SECOND RELIABILITY MODEL

Abstract

A second reliability model of the Deep Submergence Rescue Vehicle (DSRV) is defined. On the basis of this model, a prediction is made of the DSRV reliability for a typical rescue mission. The predicted reliability is computed to be 29%, for a 26-hour vehicle-operating time. The major factor contributing to the low predicted reliability of the vehicle is the high failure rate assumed for the forward and skirt (exterior) lamps. A two-orders-of-magnitude decrease in the assumed failure rate for these underwater lamps results in a predicted reliability of about 80%. Recommendations are made for improving future DSRV reliability studies.
