A Digital Bunkering Solution from order to verified delivery
In the maritime industry, fuel is far more than a line item expense. It’s the largest operating cost, the most critical emissions source, and a growing compliance risk. Yet, for many companies, bunkering remains one of the least digitized, least transparent processes on board.
Our Bunkering Software changes that completely.
Built for shipowners, ports, and suppliers, this solution manages the full fuel lifecycle from initial order to digital Bunker Delivery Note (BDN). It eliminates paperwork, automates compliance, and builds trust between stakeholders with verifiable, auditable data at every step.
End-to-End Workflow: Order to BDN
The platform delivers a seamless bunkering process:
- Fuel Order & Assignment:Initiate digital fuel orders linked to specific vessels, ports, and voyages. Orders include required fuel specs and quantities, and are connected to procurement systems and operational plans.
- Pre-Delivery Validation: Before delivery, the system verifies supplier compliance, ESG standing, and port-specific regulations. Early alerts flag issues before they impact operations.
- Real-Time Delivery Monitoring: During bunkering, live data is captured at the custody transfer point. Metrics like volume, temperature, density, and sulfur content are logged, ensuring delivery accuracy and eliminating disputes.
- Digital Bunker Delivery Note (BDN): Once delivery is complete, a digitally signed, tamper-proof BDN is created. It includes all verified measurements, timestamps, supplier and vessel credentials, and audit-ready fields. The BDN is instantly shared with relevant parties and integrated into your compliance and ESG systems.
Built-In Compliance, Ready for Regulation
Compliance is embedded in the software, reducing manual effort and audit risk:
- MARPOL Annex VI & IMO DCS: All bunker transactions are structured for regulatory compliance and ready for port inspections.
- EU ETS & CSRD: Verified fuel delivery data supports emissions reporting and sustainability disclosures.
- Scope 1 Emissions Integration: Each BDN is automatically tagged and linked to your emissions ledger, forming part of a verifiable ESG trail.
All fuel events are classified using global standards (UNSPSC, NACE) to ensure interoperability, comparability, and traceability.
Features that set you ahead
Custody transfer verification
Stop relying on disputed paperwork. The platform logs and confirms the actual quantity and quality of fuel delivered—at the moment of transfer.
Digital, secure BDNs
Say goodbye to error-prone paper documents. Each delivery ends with a verified BDN that is securely stored, digitally signed, and ready for audit.
Tamper-proof audit trail
Every action—from order to delivery—is logged with user ID, timestamp, and source data. This forms a full audit trail for compliance, dispute resolution, and investor confidence.
