A system and method for managing a plurality of instrumented function components is disclosed. In one embodiment, operating information about the plurality of instrumented function components is received from an online safety availability application and status information for the plurality of instrumented function components is updated, within an asset management database, based upon the operating information. And based upon the status information, the plurality of instrumented function components are managed.

System and method for continuous online safety and reliability monitoring

A system and method for continuous online safety and reliability monitoring is disclosed. The method includes the steps of obtaining operating information about at least one of a plurality of instrumented function components, which are part of an instrumented function, and determining a probability of failure on demand for the instrumented function based on the operating information. In variations, operating information includes status information, which may be received from and/or provided to an asset management application. In some variations, instantaneous probability of failure on demand, online mean time to failure (MTTF), and online safety integrity level (SIL) are also calculated for an instrumented function. In yet further variations, the system allows a user to predict probability of failure on demand values into the future based on hypothetical and/or future planned test times.
