Evaluating equipment efficiency is a good way to estimate the remaining life of equipment in the oil and gas industry. Performance appraisal Evaluates the structural integrity of equipment to determine whether it is suitable for its intended performance.
This type of assessment provides a quantitative estimate of the equipment structural integrity and is part of an asset management system. This assessment actually determines whether or not a piece of equipment needs to be replaced or repaired.
FFS evaluation usually requires a standard list of information including basic design conditions, building materials, and maintenance history. While this information is part of the standard record in many facilities, it is not always readily available. There are three levels of evaluation, all of which are gradual:
Level one assessment:
Level one assessment requires the least amount of data and experience. This type of evaluation usually uses tables and curves and requires little calculation. This level of inspection takes less time than the other two.
Level two assessment:
If the level one assessment does not meet the acceptance criteria on a piece of equipment, a level two assessment can be performed. Level two assessment requires much more computation to replace the simple and conservative level one assessment. Computing is usually so complex that FFS software is often required.
Level three assessment:
Compared to the previous two levels, the third level assessment requires more accurate data and a significant amount of operational experience on the part of the inspector. Level 3 analysis is rarely performed because of errors that may occur due to the use of more advanced equipment.
Factors involved in selecting the FFS level include the amount of available data for evaluation, the quality of that data, and the importance of analysis in equipment performance. Our specialists are highly experienced in developing and applying equipment performance evaluation techniques.
