Fitness for Service Assessment

Fitness-For-Service (FFS) is an essential methodology in the ‘run-repair-replace’ decision making process. There are various methods to complete assessments, but the most used methods are contained with the American petroleum Standard API-579-1 / ASME FFS-1. The Standard provides a means to assess damaged pressure equipment dependant on the mode of the damage. The damage is usually caused by some form of environmental degradation, however mechanical damage is also included. IBS help its clients provide the fixed equipment status assessments to the API-579-1/ASME FFS-1. If required by clients, we are able to select the correct inspection techniques and methods to be able to gather the pertinent equipment information that will aid complete the FFS assessment.

A fitness-for-service assessment is often used by operators to demonstrate to regulatory bodies that the condition of an asset is clearly understood and that future actions are properly planned. Assessments can be conducted for a range of different defects.
