## 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

### Claim 1

A system, comprising:
a risk assessment system comprising:
a risk calculation system configured to calculate a risk based on one or more static inputs and one or more dynamic inputs, wherein the one or more dynamic inputs comprises a location of a human resource, a mobile resource, or a combination thereof; and
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, wherein the one or more decisions are configured to aid in operating an industrial facility.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 1)

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

### Claim 5 (depends on 1)

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.

### Claim 6 (depends on 1)

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.

### Claim 7 (depends on 1)

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

### Claim 8 (depends on 1)

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

### Claim 9 (depends on 1)

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.

### Claim 10 (depends on 9)

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

### Claim 11 (depends on 9)

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.

### Claim 12 (depends on 1)

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.

### Claim 13

A method, comprising:
receiving one or more static inputs and one or more dynamic inputs, wherein the one or more dynamic inputs comprises a location of a human resource, a mobile resource, or a combination thereof;
calculating a risk based on the one or more static inputs and one or more dynamic inputs, wherein the one or more static inputs and the one or more dynamic inputs are based on an industrial facility; and
deriving a decision based on the calculation of the risk, wherein the decision comprises a determined level of the risk and is configured to aid in operations of the industrial facility.

### Claim 14 (depends on 13)

The method of claim 13, wherein calculating the risk based on the one or more dynamic inputs comprises calculating a probability of the location of the human resource, the mobile resource, or the combination thereof.

### Claim 15 (depends on 13)

The method of claim 13, wherein receiving the one or more dynamic inputs comprises detecting the location of the human resource, the mobile resource, or the combination thereof, via a plurality of sensors disposed in a confined space, a possibly hazardous area, a restricted area, or a combination thereof, in the industrial facility.

### Claim 16 (depends on 13)

The method of claim 13, comprising:
determining a first control action if the determined level of the risk is of a first level, wherein determining the first control action comprises selecting a first mitigation action; and
determining a second control action if the determined level of the risk is of a second level, wherein determining the second control action comprises selecting a second mitigation action.

### Claim 17 (depends on 13)

The method of claim 13, comprising executing via a controller a control action for controlling at least one component of the industrial facility based on the decision.

### Claim 18

A control system comprising:
a risk assessment system comprising:
a risk calculation system configured to calculate a risk based on one or more static inputs and one or more dynamic inputs received via a plurality of sensors, wherein the one or more dynamic inputs comprises a location of a human resource, a mobile resource, or a combination thereof, inside of an industrial facility;
a decision support system (DSS) configured to use the risk to provide a decision based on the risk; and
a controller configured to use the decision to execute a control action configured to control at least one component of the industrial facility.

### Claim 19 (depends on 18)

The system of claim 18, wherein the at least one component comprises a turbine system configured to provide electrical power, mechanical power, or a combination thereof.

### Claim 20 (depends on 18)

The system of claim 18, wherein the location comprises a confined space, a possibly hazardous area, a restricted area, or a combination thereof, nearby or inside a gas turbine system, a gasifier, a gas treatment system, a steam generator, an air compressor, or a combination thereof.
