Fitness-for-service assessments across Brisbane, the Gold Coast, and Australia-wide

Q-RIIMS provides API 579-based fitness-for-service (FFS) assessments to help asset owners determine whether flawed or damaged equipment can remain safely in operation. We deliver certified evaluations that support compliance, risk reduction, and reliable decision-making for critical equipment.

We assess:

  • Pressure vessels and boilers
  • Piping systems and tanks
  • Weld defects and fabrication flaws
  • Corrosion, erosion, and cracking
  • Remaining life and repair options


Applying FFS to extend equipment life and maintain compliance

Our FFS assessments provide structured evaluations that consider defect type, operating conditions, and applicable codes. By combining engineering analysis with regulatory frameworks, we help clients avoid unnecessary replacements, extend equipment life, and reduce unplanned downtime.

FFS assessments built on recognised codes

We conduct fitness-for-service evaluations according to API 579, ISO, and AS/NZS requirements. Each assessment is supported by clear documentation that meets compliance obligations and enables effective decision-making for continued safe operation.

Our services support:

  • Verification of flaw tolerance and defect criticality
  • Compliance with API 579 and AS/NZS standards
  • Documentation for audits and regulators
  • Repair planning and lifecycle analysis
