Abstract

A method and a system for analysis of turbomachinery are provided. In one embodiment, a system includes a request initiation system configured to initiate a departure request for a turbomachinery. The system further includes a commercial screening system configured to receive the departure request and to derive a commercial evaluation based on the departure request. The system also includes a technical evaluation system configured to derive a technical evaluation profile based on the departure request. The system additionally includes a request acceptance system configured to derive at maintenance action based on the commercial evaluation and the technical evaluation profile, wherein the technical evaluation profile comprises a technical analysis of the turbomachinery.

Claims

1. A system comprising:

a request initiation system configured to initiate a departure request for a turbomachinery;

a commercial screening system configured to receive the departure request and to derive a commercial evaluation profile based on the departure request;

a technical evaluation system configured to derive a technical evaluation profile based on the departure request, wherein the technical evaluation profile comprises a technical analysis of the turbomachinery; and

a request acceptance system configured to derive a maintenance action based on the commercial evaluation profile and the technical evaluation profile.

2. The system of claim 1, comprising a field execution system configured to track the maintenance action based on the technical evaluation profile.

3. The system of claim 2, wherein the maintenance action comprises a condition based maintenance interval (CBM-I) and the field execution system is configured to collect data to validate the CBM-I.

4. The system of claim 1, wherein the departure request comprises a deviation from a condition based maintenance outage (CBM-O), a deviation from a condition based maintenance interval CBM-I, or a combination thereof.

5. The system of claim 1, wherein the request initiation system is configured to use a current maintenance schedule to initiate the departure request.

6. The system of claim 1, wherein the commercial screening system comprises a cost benefit analysis model, an economic model, or a combination thereof.

7. The system of claim 1, wherein the technical evaluation system comprises a statistical analysis model, a visual inspection model, a physics-based model, or a combination thereof.

8. The system of claim 1, wherein the acceptance system comprises a regulatory model, a contractual model, or a combination thereof.

9. The system of claim 1, wherein the turbomachinery comprises a turbine, a compressor, a pump, or a combination thereof.

10. The system of claim 1, wherein the turbomachinery comprises a turbine driven generator system.

11. A method, comprising:

initiating a maintenance change request for a turbomachinery;

performing a commercial screening based on the maintenance change request;

performing a technical screening if the commercial screening determines that the maintenance change request is commercially feasible;

performing a technical risk assessment if the technical screening determines that the maintenance change request is technically feasible;

providing a technical recommendation;

deriving a maintenance action based on the technical recommendation, and executing the maintenance action if the technical risk assessment determines that a risk of the maintenance change request is acceptable.

12. The method of claim 11, wherein executing the maintenance action comprises extending a maintenance interval and collecting validation data to validate the maintenance interval.

13. The method of claim 11, wherein performing the commercial screening comprises performing a cost based analysis, an economic analysis, or a combination thereof.

14. The method of claim 11, wherein performing the technical screening comprises at least one of visually inspecting the turbomachinery, performing a statistical analysis of the turbomachinery, or performing a physics-based analysis of the turbomachinery.

15. The method of claim 11, wherein performing the technical risk assessment comprises assessing a risk of performance degradation of the turbomachinery.

16. The method of claim 11, wherein deriving the maintenance action comprises analyzing at least one of a regulatory model or a contractual model.

17. A non-transitory machine readable media, comprising:

instructions configured to initiate a maintenance change request relating to turbomachinery;

instructions configured to commercially screen the maintenance change request to produce a commercial report;

instructions configured to technically analyze the maintenance change request to produce a technical report; and

instructions configured to accept the commercial report and the technical report to produce a maintenance action.

18. The non-transitory machine readable media of claim 17, comprising instructions configured to generate a maintenance execution report based on the maintenance action.

19. The non-transitory machine readable media of claim 17, wherein the instructions configured to produce the commercial report comprise instructions configured to produce a cost based analysis, an economic analysis, or a combination thereof.

20. The non-transitory machine readable media of claim 17, wherein the instructions configured to technically analyze the maintenance change comprise instructions configured to apply a physics-based model, a statistical model, or a combination thereof.
