Abstract

A system and method for utilizing reliability data from a plant to dynamically calculate an expended life for a selected part. A system is provided that includes a central database for storing service data for different parts of a unit within the plant, wherein the service data includes installation data and a service history of the different parts; a data collection engine for dynamically collecting operational data from the plant in a near real-time manner, wherein the operational data is collected, processed and stored independently from the central database; and a lifetime calculation engine for implementing a lifetime calculation equation for the selected part, wherein the lifetime calculation equation utilizes the service data and the operational data to determine the expended life of the selected part.

Claims

1. A system embodied in a computer readable memory for utilizing reliability data from a plant to dynamically calculate an expended life for a selected part, comprising:

a central database for storing service data for different parts of a unit within the plant, wherein the service data includes installation data and a service history of the different parts including usage information from a plurality of different units in which a given part was installed;

a data collection engine for dynamically collecting a continuous stream of operational data from the plant, wherein the operational data is collected, processed and stored independently from the central database;

a lifetime calculation engine for implementing a lifetime calculation equation for the selected part, wherein the lifetime calculation equation utilizes the service data and the continuous stream of operational data obtained from the data collection engine without human intervention to dynamically calculate the expended life of the selected part in a continuous and near real-time manner; and

an output for dynamically displaying the expended life of the selected part.

2. The system of claim 1, wherein the operational data includes information selected from the group consisting of:

hours of operation, number of starts, number of trips, and operating temperature.

3. A method of utilizing reliability data from a plant to dynamically calculate an expended life for a selected part, comprising:

storing in a database static data for parts of a unit within a plant, wherein the static data includes past usage data for individual parts tracked across a plurality of different units;

collecting and storing a continuous stream of dynamic operational data from the plant in a near real-time manner without human intervention;

calculating the expended life of the selected part using a lifetime calculation equation for the selected part, wherein the lifetime calculation equation utilizes the static data and the continuous stream of dynamic operational data without human intervention and wherein the expended life is continuously recalculated in near real-time in response to changes in the continuous stream of dynamic operational data; and

outputting expended life information.

4. The method of claim 3, wherein the expended life information is dynamically outputted to display continuous recalculations of the expended life.
