- Abstract
This paper describes the Advanced Data Reception and Analysis System (ADDRESS) used for monitoring Indian Ocean moored buoys and the reliability analysis done on the data reception and dissemination performances. The system needs to be highly reliable, as the critical real-time data received from the tsunami and meteorological buoys are used for societal protection decision support systems during tsunami and cyclonic events. Driven by demanding societal needs, the developed ADDRESS with a 24/7 manned and automated Mission Control Center and the implemented system integrity proof test interval is found to conform with the IEC 61508 SIL 4 safety and reliability levels and to have an availability of 99.9938%. The graphical display capabilities developed are used for buoy deployment support, early restoration of failed moorings, and for up-keep of system components operating in remote harsh offshore environments by monitoring their performance overtime.
