BQCIS

Protecting Critical Midstream and Downstream Assets

Pipelines and aboveground storage tanks (ASTs) are vital for the safe transport and storage of crude oil, natural gas, and refined products. Over time, corrosion, cracking, and structural fatigue threaten their integrity — posing serious safety, environmental, and financial risks.

BQCIS offers comprehensive integrity management solutions including corrosion mapping, ultrasonic gauging, and tank calibration. Our inspections meet stringent global codes such as API 570, API 653, and API 579, providing quantitative data for Fitness-for-Service (FFS) assessments and predictive maintenance programs.

With certified inspectors and state-of-the-art instrumentation, we ensure that every measurement translates into actionable insight, enabling proactive maintenance, lifetime extension, and regulatory compliance.

Key Pipeline & Tank Integrity Activities

Corrosion Mapping & Ultrasonic Thickness Measurement

Using automated ultrasonic corrosion mapping, BQCIS generates high-resolution profiles of wall thickness across pipelines and vessels. This advanced inspection identifies corrosion pits, erosion, and metal loss to millimeter accuracy, providing essential input for API 579 FFS evaluations and enabling predictive maintenance decisions that prevent leaks and unplanned shutdowns.

Storage Tank Inspection & Calibration

Certified API inspectors perform complete tank shell, floor, and roof inspections under API 653 and EEMUA 159. Our calibration and strapping surveys generate precise volume tables for custody transfer and inventory control. Data integrity and traceability are ensured through digital reporting and tamper-proof calibration records.

Key Benefits of Pipeline & Tank Integrity Services

Integrity

Extended Asset Life

Corrosion mapping and FFS assessments allow strategic repair and maintenance planning, extending asset lifespan cost-effectively.

Compliance

Regulatory Compliance

Our inspections meet API, ISO, and local environmental requirements—ensuring operator compliance and audit readiness.

Accuracy

Accurate Custody Transfer

High-precision tank calibration guarantees exact volume determination for fair trade settlement and inventory accounting.

Risk Reduction

Reduced Environmental Risk

Early detection of corrosion or wall loss prevents leaks, protecting surrounding ecosystems and minimizing liability exposure.

Success Story

Corrosion Mapping Prevents Critical Pipeline Failure

The Challenge:

A petrochemical operator required detailed wall-thickness data on a buried effluent line suspected of severe corrosion to decide between repair and full replacement.

Our Solution:

BQCIS performed Automated Ultrasonic Corrosion Mapping over the exposed section, producing a color-coded thickness map. This dataset identified localized metal loss below design limits and allowed precise engineering evaluation.

The Result:

The high-accuracy map supported a targeted repair rather than full replacement, saving significant capital cost while avoiding an environmental incident. The verified data was later used in the client’s formal FFS documentation and risk-based inspection plan.
