FFS assessment

The Fitness For Service assessment (FFS) allows to ensure safe and reliable operation of process equipment, such as pressurized vessels, reactors and storage tanks, for a desired time.

The procedure evaluates the equipment's residual resistance in it's actual state, which could have been degraded by: corrosion, hydrogen attack, fatigue, creep and mechanical distortion.

This constitutes the foundation for:

> Inspection planning

>Define the requirements for equipment improvements or rerate.

>Quantify the equipment's reliability.

Can be integrated with:

> RBIM Assessment

> Service life assessment

> Condition monitoring

Is complemented with:

> Strain, acceleration, thickness
or other measurements.

> Failure analysis

> Process simulation
