Every bunker delivery verified against ISO 8217 standards through a three-stage chain: supplier test report, BDN delivery specs, and independent lab analysis. Deviations trigger automatic disputes.
Before delivery, the supplier sends their fuel test report. Your analyst logs the specs — density, viscosity, sulfur, cat fines, CCAI, flash point. This sets the baseline expectation for the delivery.
At delivery, the Bunker Delivery Note records the actual fuel specs. TRIVOYA compares BDN values against the supplier's pre-delivery test report. Any deviations are flagged immediately.
Your retained sample goes to FOBAS or VPS for independent analysis. Lab results are compared against both the BDN and the supplier test report. If cat fines, sulfur, water, or density deviate beyond thresholds — a dispute is auto-created.
Every delivery receives a quality score from 0-100 based on 10+ parameters measured against ISO 8217:2017 limits and supplier-port baselines.
| Parameter | ISO 8217 Limit (RMG 380) | What It Means | Engine Risk |
|---|---|---|---|
| Cat Fines (Al+Si) | ≤60 mg/kg (15 onboard) | Aluminium silicate catalyst particles from refinery cracking | Critical — causes cylinder liner wear, piston ring damage |
| Sulfur | ≤0.50% (VLSFO) | Regulatory limit under IMO 2020 | Port State Control detention if exceeded |
| Water | ≤0.50% | Water contamination in fuel | Injector damage, corrosion, microbial growth |
| Viscosity | Depends on grade | Flow characteristics at operating temperature | Affects injection timing and atomization |
| Density | ≤991 kg/m³ | Mass per volume — affects purifier separation | Over 991: purifier cannot separate water/sediment |
| CCAI | ≤870 | Calculated Carbon Aromaticity Index — ignition quality | High CCAI = poor combustion, after-burning |
| Flash Point | ≥60°C | SOLAS safety requirement | Below 60°C = fire/explosion risk, vessel detained |
When lab results deviate from BDN specs beyond thresholds, TRIVOYA auto-creates a dispute case with estimated claim value, supplier history, and supporting evidence.
System compares lab values against BDN. If cat fines, water, sulfur, or density exceed limits, a dispute case is created with severity classification (critical/high/medium) and estimated financial claim.
Track open disputes by case number, supplier, vessel, and estimated claim. Open/close toggle for each case. Full audit trail of the verification chain — test report, BDN, and lab values side by side.
Monitor total claims raised vs total recovered. Recovery rate by supplier. Dispute history feeds into supplier scorecards — persistent quality issues automatically reduce a supplier's quality ranking.
Quarterly reports show total disputes, $ recovered, and supplier quality trends. Clients see the value of quality management — dispute recoveries often pay for the entire platform subscription.
