BQCIS

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

Data Compilation & Review

Collecting design documents, inspection records, and service history to establish a baseline for analysis.

Damage Mechanism Evaluation

Identification of active degradation modes such as corrosion, fatigue, creep, or hydrogen embrittlement.

Non-Destructive Examination (NDE)

Integration of NDT results including ultrasonic, radiographic, and magnetic particle testing to determine flaw size and location.

Stress & Fracture Analysis

Finite element analysis and residual stress assessment to predict component strength under operational loads.

Remaining Life Assessment

Determining safe operational duration before repair or replacement becomes necessary.

Engineering Recommendations

Providing repair, rerate, or decommissioning guidance based on engineering evaluation results.

Documentation & Reporting

Preparation of FFS assessment reports including critical findings and compliance certificates.

Follow-Up Verification

Validation of implemented corrective actions and updated inspection plans for continuous assurance.

Regulatory Compliance Support

Ensuring that all FFS assessments and recommendations align with relevant industry codes and local regulations.

Key Benefits of Equipment Fitness-for-Service

Operational Continuity

Operational Continuity

Supports safe, uninterrupted operation by verifying equipment remains structurally sound for service.

Reduced Downtime

Reduced Downtime

Prevents premature replacement by identifying equipment that can continue operation safely.

Extended Asset Life

Extended Asset Life

Optimizes lifecycle management through accurate evaluation of degradation and remaining strength.

Regulatory Compliance

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

The Challenge:

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.

Our Solution:

BQCIS engineers performed Level 2 and Level 3 analyses per API 579, integrating ultrasonic thickness data and finite element stress simulations.

The Result:

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.
