Service Levels & SLA

We structure service delivery into three tiers — Express, Standard, and Complex — ensuring scalability and predictability.
Each SLA is benchmarked to industry KPIs and tied to your operational demands:

• Express — Inspections within 24–72h, next-day reporting, priority inspector allocation.
• Standard — Routine inspections with full laboratory testing and predictable turnaround cycles.
• Complex — Multi-stream, multi-site programs, ship-to-ship transfers, or seasonal peak operations.

Performance is measured against KPIs such as volume variance, report timeliness, resample rates, and retained sample integrity — with results accessible in the
BQCIS Client Portal.

What We Do (Detailed)

BQCIS provides end-to-end assurance services across the energy value chain, helping clients safeguard value, prevent disputes, and ensure compliance.
Our methodologies are proven, defensible, and internationally recognized.

Cargo Inspection & Loss Control

• Shore & ship tank gauging, temperature & density verification.
• Ullage/sounding checks, displacement validation, custody reconciliation.
• Supervision of bunkering and de-bunkering operations.

Sampling & Laboratory Testing

• Closed/restricted sampling, composite & spot collection.
• Jet A-1: density, flash point, FAME, freezing point.
• Diesel/Gasoline: RON/MON, distillation, sulfur, cetane index.
• Crude oil & marine fuels: API gravity, viscosity, cat fines, BS&W.
• Petrochemicals: purity, inhibitors, contaminants testing.

Tank Calibration & Metering Verification

• Calibration of vertical & horizontal tanks with strapping/proving charts.
• Flow prover coordination & meter factor checks.

Pipeline & Terminal Oversight

• Line displacement verification & interface detection.
• Additive injection witnessing, custody seals, valve status logs.

Documentation & Release

• Reports with calculations, calibration references, and dip charts.
• Settlement backed by QR-secure certificates.

Terminal oversight — Independent custody transfer supervision

How We Work: Inspect · Sample · Test · Reconcile · Certify

Our methodology follows a structured process to ensure accuracy, transparency, and defensibility of every inspection.

Inspect

• Confirm tank/line conditions, seals, permits, and safety readiness.
• Visual inspection supported by photographic logs.

Sample

• Correct ISO/ASTM methods, custody-sealed containers.
• Chain-of-custody documentation from collection to lab delivery.

Test

• Targeted laboratory panels matched to product stream/specification.
• Accredited laboratory facilities under ISO 17025.

Reconcile

• Apply corrections, cross-check gauges/meters, variance analysis.
• Discrepancy thresholds aligned with international tolerance rules.

Certify

• Final reports issued with calculations, seals, photos, and QR-secured certificates.

This step-by-step framework ensures results that are transparent, trusted, and defensible in any jurisdiction.

Crude & Fuel Laboratory Testing

Our laboratories perform comprehensive analysis of crude oils, refined fuels, and petrochemicals
to verify compliance with
ISO
and
ASTM standards.
Results are defensible, fully traceable, and secured through the
Digital Assurance Hub.

• Distillation & Flash Point:
  ASTM D86, D93 protocols for fuels.
• Sulfur & Contaminants: ICP, XRF, Karl Fischer moisture analysis.
• Performance Indicators: Cetane index, RON/MON for gasoline.
• Marine Fuels: Cat fines, viscosity, water content, sulfur compliance under
  IMO.
• Crude Oils: API gravity, BS&W, salt content.

These analyses underpin customs clearances, trade settlements, and refinery compliance worldwide.
