Ensuring Safe and Reliable Operation of Critical Assets
BQCIS conducts Fitness-for-Service (FFS) evaluations to determine the continued safe operation of pressure vessels, piping systems, storage tanks, and rotating equipment. By combining inspection results with advanced engineering analysis, we quantify remaining life and integrity risks.
Our approach is aligned with API 579, ASME FFS-1, and RBI (Risk-Based Inspection) methodologies — providing clients with engineering assurance for repair, rerating, or continued operation decisions.
Each FFS study includes data collection, damage mechanism identification, stress analysis, and a full engineering assessment of degradation modes including corrosion, cracking, deformation, and weld defects.
Key Activities in Equipment Fitness-for-Service
Key Benefits of Equipment Fitness-for-Service
Operational Continuity
Supports safe, uninterrupted operation by verifying equipment remains structurally sound for service.
Reduced Downtime
Prevents premature replacement by identifying equipment that can continue operation safely.
Extended Asset Life
Optimizes lifecycle management through accurate evaluation of degradation and remaining strength.
Regulatory Compliance
Demonstrates adherence to API and ASME FFS standards to satisfy safety and audit requirements.
Success Story
Pressure Vessel Fitness Evaluation for Petrochemical Facility
An oil & gas operator required a third-party FFS assessment of a corroded reactor vessel to determine whether continued service was safe under current operating pressures.
BQCIS engineers performed Level 2 and Level 3 analyses per API 579, integrating ultrasonic thickness data and finite element stress simulations.
The vessel was deemed fit for continued operation with minor derating, saving the client over $1.2 million in replacement costs while maintaining safety compliance.
