Our Fitness-For-Service (FFS) Assessment provides a rigorous engineering evaluation of in-service mechanical equipment to determine its suitability for continued operation in the presence of damage, deterioration, or deviations from original design conditions. The assessment supports informed decisions where corrosion, metal loss, cracking, deformation, or other flaws are identified during inspection or operation. It applies to critical oil and gas plant equipment including pressure vessels, piping systems, heat exchangers, tanks, and other pressure-retaining components.

The assessment is performed using a structured, code-based methodology that integrates inspection data, operating conditions, material properties, and degradation mechanisms. Quantitative evaluations are carried out to assess remaining strength, failure margins, and safe operating limits. Where required, the study includes assessment of corrosion allowances, crack acceptability, local and general metal loss, and re-rating or derating scenarios. Assumptions, limitations, and conservatism levels are clearly documented to ensure transparency and engineering robustness.

The outcome of the FFS Assessment is a clear, defensible basis for operational decision-making. Clients benefit from avoiding unnecessary repairs or premature replacement while ensuring safety and regulatory compliance. The study provides confidence to continue operation, define repair timelines, optimise inspection intervals, and support turnaround or life-extension planning—balancing risk, safety, and cost effectively.
