Pipelines and terminals are the most sensitive custody points in the energy and petrochemical supply chain.
BQCIS provides independent oversight of line displacements, additive injections, and custody seals, ensuring
full transparency and compliance with ISO,
API, and
ASTM standards.
Our inspectors log every intervention into the
Digital Assurance Hub, creating a defensible chain-of-custody record.

Line Displacement & Verification

• Monitoring of line clearing, displacement volumes, and interface segregation.
• Photo and seal-logged evidence attached to custody transfer certificates.
• Defensible reconciliation to prevent product mixing or loss.

Additive Injection & Blending Oversight

• Witnessing of dye, marker, and inhibitor injections at terminals.
• Independent verification of dosage rates, batch records, and blending procedures.
• Aligned with customs and excise rules for taxation and trade controls.

Custody Seals & Valve Logs

• Application and recording of tamper-proof seals across valves, flanges, and manifolds.
• QR-secured seal logs integrated into the
  Digital Assurance Hub.
• Randomized inspector audits to ensure integrity across high-risk locations.

Terminal Operations Oversight

• Independent supervision of ship-to-terminal, truck-to-terminal, and terminal-to-pipeline transfers.
• Monitoring of interface detection, line flushing, and contamination prevention.
• Variance logs maintained for customs and arbitration defense cases.

• API MPMS — Custody transfer measurement
• ISO Standards — Terminal and pipeline oversight
• ASTM Methods — Additive and blending controls

• Digital Assurance Hub — QR-secured seal and custody records
• Case Studies — Pipeline & terminal dispute resolutions
