Fitness for Service

Fitness-for-service Analysis

Fitness for Service (FFS) assessment is performed to make sure that process plant equipment, such as pressure vessels, piping, and tanks, will operate safely and reliably for some desired future period.

CANEIL provides fitness for service assessment according to API Recommended Practice 579. The assessment procedure evaluates the remaining strength of the equipment in its current condition, which may be degraded from its original conditions.

Common degradation mechanisms include general metal loss, localized corrosion, pitting and crevice corrosion, hydrogen attack, embrittlement, fatigue, high-temperature creep, and mechanical distortion. Methods for evaluating the strength and remaining service life of equipment containing these types of degradation are presented and reviewed.

CANEIL's staff have extensive experience in dealing with FFS assessments, including deformation, cyclic operation, general metal loss, and weld defects.

One of CANEIL's biggest advantages to our competitors shows in our ability to send out a single crew with all of the skills necessary for conducting fitness-for-service assessments. Conducting the inspections, non-destructive examinations, and analysis of the data within the organization itself allows for a quicker turn-around and more reliable results.
