BQCIS methodologies are designed to ensure **reliable, repeatable, and defensible results** during
daily terminal monitoring. These standardized steps, aligned with
ASTM,
ISO, and
BQCIS QR verification protocols,
provide transparency across shared facilities.

1. Gauging & Measurement

• Daily soundings and ullage readings from all storage tanks.
• Temperature and density measured at multiple tank levels.
• Automatic Tank Gauging (ATG) systems verified against manual readings.

2. Calibration & Conversion

• Application of ASTM D1250 petroleum measurement tables.
• Verification of tank strapping charts and calibration certificates.
• Conversion of Gross Observed Volume (GOV) to Net Standard Volume (NSV).

3. Line Displacement & Stratification

• Recording and reconciliation of pipeline movements.
• Stratification checks to detect layered product conditions.
• Sampling protocols applied to confirm homogeneity.

4. Variance Tracking

• Comparison of operator logs vs. physical measurements.
• Variance thresholds set (e.g., ±0.3% for refined fuels).
• Immediate notification when deviations exceed limits.

5. Reporting & Transparency

• Daily reports with gauges, density, and calculation sheets.
• Photo-logged evidence of tank levels, seals, and conditions.
• Reports issued with
  QR-secured traceability.

• ASTM D1250 — Petroleum Measurement Tables
• ISO 45001 — HSSE management framework

• BQCIS QR Certificates — Verified measurement packs
• Client Portal — Daily monitoring dashboards
