What is the general Relaiability/Availability figures of Oil and Gas Rotating Equipment. Just want to refer our equipment reliability with similar ones in the industry. Is there any industrial guideline to set target KPI.

I thought OREDA databank book would have this info. Pls pruchase or get the latest edition for latest data.

Josh,
OREDA has failure data, not Availability or Reliability data.

Rephrased, I thought OREDA would contain those failure data which can be used for calculation of equipment reliability figures, at least a range.

Josh,
The failure rate data is given as the range (min, max) and mean values. The range can be very large, max/min may sometimes be 1000 or more. Mean values need not be representative of your installation.
Also the failure rate data is at Functional Failure level, e.g. Stopped while running or Fail to start. This can be decomposed into the Failure mode level by using decomposition tables which are provided, but there are many possibilities to introduce errors.
Failure rates are a measure of Reliability, but at the Failure Mode level, not at Equipment level, where several FMs may contribute.
Thus OREDA has its uses, but not for benchmarking Reliability: Availability is even more complex, so we are better off looking at actual run length performance of our equipment, using field data.

Karthik,

Before setting up the targets for the Reliability and Availability of your machines, you should first calculate the Rel / Availability performance of your machines.

Also you need to evaluate the production capacity (normal operation) in addition to the equipment configuration. e.g for n+1 configuration, you could consider keeping availability target lower than as compared to n+0 where you have no redundancy, where you need to have higher availability target.

To have realistic targets for Rel / Ava, you should have a clear approach. Just by selecting a target of 98 or 99 % from top of the head would not help in improving the performance.
