Safely Extending the Value of Your Aging Assets
Many critical industrial assets — from power plants and refineries to offshore structures — are operating beyond their original design life. Replacing these assets is often prohibitively expensive. Lifetime Extension (LTE) Studies provide the engineering justification to continue safe operation by combining inspection, analysis, and predictive modeling.
BQCIS performs detailed reviews of design, operational, and maintenance data, identifies degradation mechanisms such as corrosion, fatigue, and creep, and executes targeted inspections to quantify current condition. Using Fitness-for-Service (FFS) assessments in accordance with API 579, our engineers evaluate the asset’s residual strength and estimate its remaining useful life.
Our multidisciplinary teams of mechanical, materials, and NDT specialists deliver data-driven reports that outline the engineering requirements, inspection intervals, and modifications necessary to safely extend the operational life of your critical infrastructure.
Key Life Extension Activities
Key Benefits of Lifetime Extension Studies
Reduced Capital Expenditure
Eliminate unnecessary replacements through validated engineering justification for continued operation.
Verified Structural Integrity
Comprehensive FFS evaluations ensure all components meet design safety margins for extended service.
Improved Risk Management
Accurate degradation models allow proactive mitigation of potential failures and unplanned downtime.
Extended Asset Life
Enable safe, cost-effective operation beyond original design life with confidence in continued integrity.
Success Story
Asset Integrity Study Safely Extends Vessel Life by 10 Years
A petrochemical facility approached the end of a pressure vessel’s design life. Replacing it would require significant capital investment and production loss.
BQCIS conducted a detailed life extension study combining advanced NDT (PAUT & TOFD) with engineering assessment per API 579. Historical performance data and inspection records were fully reviewed.
The FFS analysis verified the vessel’s continued fitness for service with minor modifications. The study provided regulatory approval for a 10-year life extension, avoiding costly replacement and minimizing downtime.
