Our Facility Assessment and Remaining Life Assessment (RLA) service provides a structured and evidence-based evaluation of the mechanical integrity, fitness-for-service, and residual life of critical oil and gas plant equipment. The study focuses on pressure vessels, piping systems, heat exchangers, storage tanks, and static mechanical equipment operating under demanding process, corrosion, and environmental conditions. The objective is to establish a clear understanding of current asset condition and its ability to operate safely and reliably within defined design and regulatory limits.

The assessment integrates document review, operating history, inspection data, degradation mechanism identification, corrosion rate evaluation, and engineering calculations to determine remaining life and potential end-of-life scenarios. Applicable international codes, inspection standards, and industry best practices are applied to assess metal loss, cracking, fatigue, creep, and other damage mechanisms. Where required, fitness-for-service and remaining strength evaluations are performed to support continued operation decisions and inspection interval optimisation.

The outcome of the study is a practical, decision-oriented report that supports asset integrity management, life extension strategies, and capital planning. Clients benefit from clear recommendations on repair, replacement, re-rating, inspection prioritisation, and risk mitigation measures. This study enables operators to improve safety, ensure regulatory compliance, reduce unplanned shutdowns, and make informed decisions on extending the operational life of aging facilities while managing cost and risk effectively.
