Our designers are mechanical engineers with 20+ years of relevant experience .
Fitness for Service (FFS) is a best practice and standard used by the oil & gas and chemical process industries for in-service equipment to determine its fitness for continued service. FFS serves as a rational basis for defining flaw acceptance limits and allows engineers to distinguish between acceptable and unacceptable flaws and damage based on industry.
SA-FFS has carried out FFS assessments on pressure vessels, slug catchers, storage tanks, pipelines, piping system and high-temperature equipment in accordance with industry-accepted standards.
The FFS of any particular material is determined by performing a fitness-for-service assessment per standardized methods and criteria. Performing accurate FFS evaluations is an integral aspect of fixed equipment asset integrity management as an alternative to using the original construction design code. The FFS of a piece of equipment may be viewed both in terms of current and future FFS or remaining life.
Most equipment can continue in service despite small flaws, and to repair or replace equipment that can still be used would be an unnecessary and costly expense. In addition, unnecessary weld repairs can do more harm than good and create unnecessary risks to personnel in many cases.
API RP 579-1/ASME FFS-1, Fitness for Service, Second Edition, is one example of a FFS methodology currently used by industry professionals. In general, most FFS assessment standards are broken into multiple levels. Each successive level (e.g., Levels 1, 2 and 3 of the referenced API 579-1/ASSME FFS-1 standard) requires increasing amounts of data, calculations, effort, and cost to arrive at the most accurate outcomes and possible longer equipment remnant life.
In addition to calculations, FFS involves the consideration of additional data (e.g. pitting patterns and depths, corrosion morphology or shape and depth, crack depths and lengths, operating conditions, materials properties, etc.). Inspection information is often critical input to a FFS assessment.
Through established multidisciplinary teams, with specialist knowledge in areas of fracture mechanics, fatigue, finite, materials, inspection and welding, SA-FFS is able to provide industry-leading services to its international network of Industrial Member companies.
SA-FFS wide-ranging expertise is regularly used to develop non-standard testing and assessment methodologies, conforming to the API 579/ASME FFS-1 Level 3 classification.
This capability allows us to take on and solve problems where non-standard geometry, unusual loading, or exotic materials mean that standard FFS approaches are unsuitable.
In order to maximize productivity, your pressure vessels and equipment need to be maintained regularly.
SA asset integrity consulting services maintain your assets to ensure productivity, reliability and safety.

How IT is WORKING ?
SA-FFS started with gathering data regarding your pressure vessels .
SA-FFS technical team to study all available data and request additional data if required .
SA-FFS team design the inspection required either intrusive or NON intrusive and send back to Client for study , agree and implement and send back reports
SA-FFS team will study the new inspection reports for compliance with the a/m plan .
SA-FFS team to run FFS calculations , actual corrosion rate , remaining life time , recommended repairs if any .
Fitness for service Assessment evaluate the structural integrity of components and their suitability for continuous service.
Fitness for service Assessment provides a quantitative measure of the structural integrity of a component containing flaws.
Standards used to carry out these assessments (like API 579-1) provide guidelines which can be used to make run-repair-replace decisions.
Fitness for service Assessment Assisting plant management with identifying appropriate mitigation actions to ensure that the component can be operated safely.
The Fitness for service Assessment can be used to support design, fabrication, operation, change of service and life time extension.
Fitness for service assessment can quickly determine if equipment is safe for immediate return to service.
