Fitness for Service Assessment (FFS)

Fitness For Services (FFS) assessments are quantitative engineering evaluations performed to demonstrate the structural integrity of an in-service component containing a flaw or damage.

FFS is a methodology whereby flaws contained within a structure are assessed to determine the adequacy of the structure for continued service without failure.

API RP 579-1/ASME FFS-1, Fitness-For-Service 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 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 such as pitting patterns and depths, corrosion morphology, crack depths and lengths, operating conditions, and material properties.

Inspection information is often critical input to a FFS assessment.

Types of Damages Assessed via FFS

We work according to the international code API 579-1 / ASME FFS-1 “Fitness-For-Service” published by API and ASME.

Depending on the level of complexity in each situation, we distinguish between Level 1 to Level 3 required and we do so always in accordance with API 579-1 / ASME FFS-1.

Providing Complete Fitness for Service Assessments

Petromaster Ltd routinely conducts fitness-for-service assessments of pressure vessels, piping systems, and storage tanks using API 579 guidelines.

Our engineers and associated strategic partners can provide complete fitness-for-service, mechanical integrity, and remaining-life services.

These services include field inspections and data collection, laboratory mechanical and chemical testing, and cost-effective engineering solutions.
