The operation reliability of arc-type ship’s anti-collision facility directly relates to daily operational flexibility and security, so it is of great significance to study it. The operation reliability is quantified to the possibility that driving force is bigger than the resistance with the performance reliability evaluation model.In order to improve the test efficiency, the test program is optimized by the enhanced test model. The mechanism model is established, and four strain measurement units are laid on the junction between collision belt and buoy.The mechanism model test results show that, under the condition of strengthened test, no abnormal output occurs in 25 test cycles and the buoy stuck didn’t appear in 25 test cycles. It proves that the design of the facilities meets the reliability requirements.
