Abstract

A system includes a risk assessment system. The risk assessment system includes a risk calculation system configured to calculate a risk based on one or more static inputs and one or more dynamic inputs. The one or more dynamic inputs includes a location of a human resource, a mobile resource, or a combination thereof. The risk assessment system further includes a decision support system (DSS) configured to use the risk to derive one or more decisions based on the risk, the one or more static inputs, and the one or more dynamic inputs. The one or more decisions are configured to aid in operating an industrial facility.

Claims

a processor configured to execute a risk assessment system of a gas turbine system, comprising;

a risk calculation system executed by the processor and configured to calculate a risk based on one or more static inputs and one or more dynamic inputs, wherein the risk calculation system is configured receive the one or more static inputs and the one or more dynamic inputs from a sensor as an indication of a location of a human resource, a location of a mobile resource, or a combination thereof, and wherein the risk calculation system is configured to update the risk based on signals received from the sensor and based on a current measurement of an operating condition of the gas turbine system; and

a decision support system (DSS) executed by the processor and configured to use the risk to derive one or more decisions based on the risk, the one or more static inputs, and the one or more dynamic inputs, wherein the one or more decisions are configured to aid in operating an industrial facility comprising the gas turbine system.

2. The system of claim 1, wherein the risk calculation system comprises a statistical model, a physics-based model, a heuristic model, or a combination thereof.

3. The system of claim 1, wherein the risk calculation system comprises an accident scenario review (ASR) model configured to derive the probability of an undesired work stoppage event, an accident, or a combination thereof.

4. The system of claim 1, wherein the risk calculation system is configured to calculate the risk comprising multiple layers of concurrent contributing risk factors.

5. The system of claim 1, wherein the one or more static inputs comprises a design data, a manufacturing data, a plant configuration, a failure mode analysis, a regulation, a margin for unknown factors, or a combination thereof.

6. The system of claim 1, wherein the one or more dynamic inputs comprises a plant instrumentation input, a plant equipment input, a plant external independent systems data, a business environment input, an external systems input, a replacement of unknown factors input, a human resources input, a mobile resources input, or a combination thereof.

7. The system of claim 1, wherein the location of the human resource, the location of the mobile resource, or the combination thereof, comprises a confined space, a possibly hazardous area, a restricted area, or a combination thereof, within the industrial facility.

8. The system of claim 1, wherein the DSS is configured to derive the one or more decisions via determining a level of the risk.

9. The system of claim 1, comprising a controller configured to use the one or more decisions to execute a control action configured to control at least one component of the industrial facility.

10. The system of claim 9, wherein the control action corresponds to at least one determined risk level.

11. The system of claim 9, wherein the control action comprises an alarm, an operator intervention, an isolation of the at least one component, a shutdown of the at least one component, or a combination thereof.

12. The system of claim 1, wherein the DSS is configured to use an event rule, a mitigation action algorithm, a recommended action algorithm, a risk calculation algorithm, a failure prediction algorithm, a model updating algorithm, an action scheduling algorithm, or a combination thereof, to derive the one or more decisions.

21. The system of claim 1, wherein the risk calculation system is configured to update the risk continuously during operations of the industrial facility based on the signals received from the sensor.

13. A method, comprising:

receiving one or more static inputs and one or more dynamic inputs from a plurality of sensors, wherein the plurality of sensors are configured to provide an indication of a location of a human resource, a location of a mobile resource, or a combination thereof, as the one or more dynamic inputs;
