There is a vast number of different components used on an oil rig and each one may have a different definition of new, worn, damaged, or depleted. The system includes a measurement component that takes a measurement of the different components, and a health modeling component which calculates the standardized Health Index. Monitoring the Health Indices provides a rig operator information from which decisions on equipment use can be made. ## Claims ### Claim 1 A system for deriving a numerical Health Index for one or more components, the system comprising: a first component having a first feature which decays when the first component is operated, wherein the first component comprises part of a drilling rig; a second component having a second feature which decays when the second component is operated, wherein the second component comprises another part of the drilling rig, and wherein the second component is different from the first component;

taking a second measurement of a feature of a second component, wherein the second component comprises another part of the drilling rig, and wherein the first and second components are different; calculating a first Health Index and a second Health Index from the first and second measurements, respectively, wherein the first and second Health Indices are on a same scale; monitoring at least one of the first and second Health Indices relative to a predetermined Health Index threshold; and altering operation of the first and second components to cause the first and second Health Indices to reach the predetermined Health Index threshold at a same time, wherein an operation of the drilling rig is stopped to perform maintenance on the first and second components when the first and second Health Indices reach the predetermined Health Index threshold, and wherein causing the first and second Health Indices to reach the predetermined Health Index threshold at the same time reduces an amount of time that the operation of the drilling rig is stopped. ### Claim 15 (depends on 14) The method of claim 14 wherein the predetermined Health Index threshold is a first predetermined Health Index threshold, the method further comprising monitoring the at least one of the first and second Health Indices relative to a second predetermined Health Index threshold different from the first predetermined Health Index threshold. ### Claim 16 (depends on 15) The method of claim 15 wherein the first predetermined Health Index threshold has a first associated suggested action and the second predetermined Health Index threshold has a second associated suggested action different from the first associated suggested action. ### Claim 17 (depends on 16) The method of claim 16 wherein the first associated suggested action is performing the maintenance, and the second associated suggested action is shutting down the first and second components. ### Claim 18 (depends on 14) The method of claim 14, further comprising recalculating at least one of the first and second Health Indices after performing the maintenance. ### Claim 19 (depends on 18) The method of claim 18, further comprising: comparing at least one of the first and second Health Indices after the maintenance to itself before the maintenance; and calculating a numerical score representing an effect of the maintenance corresponding to a difference between the at least one of first and second Health Indices before and after the maintenance. ### Claim 20 (depends on 14) The method of claim 14, wherein altering the operation of the first and second components changes the first Health Index, the second Health Index, or both. ### Claim 21 A method for predicting a health of one or more components of an oil rig, the method comprising: calculating a first Health Index for a first component of the oil rig;
