Risk Analysis

Glossary

Analysis Date: information up to this date was used for the following risk analysis. Most likely this is the most recent complete diagnostic data set received on the given turbine. We may have some data since that date, but we do not have more recent diagnostic data. Therefore the risk analysis is dated from the Analysis Date.

Failure Probability: the likelihood that the given asset or component will have an unscheduled failure in the proceeding 90-900 days from the Analysis Date. Red means the probability is very high; Orange means high; Green means low; Neutral means that there is no identifiable probability in either direction. Failure Probability is a function of the Severity and Similarity of the risk analysis.

Severity: the gearbox risk analysis algorithm identifies similar gearboxes and assesses the health of these similar gearboxes. The severity is a measure of the health of these similar gearboxes. High severity signifies that similar gearboxes are in very poor health. Low Severity signifies that similar gearboxes are not in poor health.

Similarity: the gearbox risk analysis algorithm identifies similar gearboxes and assesses the health of these similar gearboxes. The Similarity is a measure of how similar the identified gearboxes are to the gearbox being analyzed. High Similarity means that the similar gearboxes are very similar. Low Similarity means that the similar gearboxes are not similar.
