Capture, verify, sign and connect every bunker in real time
Bunker delivery touches suppliers, vessels, surveyors, ports and finance teams, yet the documentation that connects them too often arrives late, in the wrong format, or open to dispute. One platform brings every step together: pre-delivery, capture, validation, signing, blockchain verification and downstream reporting for faster settlement, fewer disputes and stronger compliance.
Replace paper-based delivery workflows
Capture bunker delivery data digitally at the point of transfer. Eliminate manual documentation, reduce errors and ensure consistent, structured data across every transaction for suppliers, vessels and surveyors alike.

Full traceability across every transaction
Maintain a complete, tamper-proof record of bunker delivery data. Support regulatory requirements and internal governance with structured, auditable documentation.
Find out moreOne signature flow: supplier, buyer, surveyor, port
Suppliers, receiving vessels, surveyors and port authorities all sign the same eBDN digitally: no paper hand-offs, no scanned PDFs, no version drift. A single sign-off covers pre- and post-delivery, freeing up barge time so crews can complete more deliveries per day or reduce idle time between operations.

How ZeroNorth eBDN works
ZeroNorth eBDN digitises the entire bunker delivery workflow, from pre-delivery notification through to post-delivery reconciliation, replacing paper-based documentation with a structured, verified digital record.
Capture at source
Crews capture bunker delivery data digitally at the point of transfer. A single sign-off covers pre- and post-delivery, freeing up barge time for the next operation.
Multi-party e-signing
Supplier, vessel, surveyor and port authority sign the same eBDN digitally. No paper hand-offs, no scanned PDFs, no version drift.

Blockchain verification
Every completed eBDN carries a tamper-proof blockchain fingerprint. Disputes about quantity, grade or timestamp are resolvable in seconds, not weeks.
Procurement integration
eBDN data transfers automatically into procurement systems on completion. Quantity discrepancies are flagged before settlement, accelerating payment cycles.
The ZeroNorth advantage
Intelligence built for real maritime operations at scale.

Integrated across procurement and performance
eBDN connects directly with ZeroNorth Bunker Procurement, Voyage Optimisation and Emission Analytics. Delivery data flows into purchase reconciliation, voyage fuel accounting and CII and EU ETS reporting without manual re-entry and without spreadsheet reconciliation.
Structured, verified data at source
Capture delivery data digitally at the point of transfer. 200+ embedded validation checks flag bad data before it lands in your systems. Accuracy starts at the barge, not in back-office reconciliation.
Built for audit and compliance
Every transaction is recorded as an electronically verifiable PDF: tamper-proof, blockchain-fingerprinted and ready for any auditor or regulator. MPA-whitelisted in Singapore and SGTraDex-integrated for trusted data sharing across the bunker supply chain.

What is an eBDN?
An electronic Bunker Delivery Note (eBDN) replaces traditional paper-based delivery documentation with a digital, structured record of bunker transactions.
How does blockchain verification work for an eBDN?
Every completed eBDN carries a blockchain fingerprint, a unique cryptographic record that any third party can verify. Delivered quantity, fuel grade and timestamps are tamper-proof: if any data point is altered after sign-off, the verification fails. Disputes become resolvable in seconds rather than weeks.
How does eBDN reduce reconciliation risk?
By capturing and validating delivery data at source, eBDN ensures alignment between delivered quantities and contractual terms. Discrepancies are flagged in real time, reducing disputes, settlement claims and manual reconciliation effort across both buyer and supplier finance teams.
How does eBDN integrate with procurement workflows?
Delivery data is transferred directly into procurement systems on completion, automatically matching against supplier orders and initiating payment processes without manual intervention. Quantity discrepancies are flagged before settlement, and both buyers and suppliers operate from the same verified data record.
How much time does eBDN save per bunkering event?
Operators using ZeroNorth eBDN save an estimated 30-60 minutes per bunkering event, time previously spent preparing, reviewing, printing and archiving paper BDNs. For a fleet running 500 bunkering operations a year, that translates to over 375 man-hours saved annually. Documentation processing time drops by up to 50%, and barge utilisation improves through faster delivery turnaround.
What does MPA whitelisting mean for eBDN?
MPA whitelisting is the Maritime and Port Authority of Singapore's designation for eBDN solutions that have passed comprehensive testing for regulatory compliance, data accuracy and security. Singapore is the world's largest bunkering hub, and the MPA is moving to mandate eBDN across all Singapore bunker deliveries. ZeroNorth is one of a select few providers to hold this designation.
Does eBDN require onboard hardware?
No. eBDN integrates with existing reporting workflows and systems, minimising implementation effort while improving data accuracy. Crews access the platform through standard web and mobile interfaces.
Who uses ZeroNorth eBDN?
Bunker suppliers, both back-office teams and barge crews, are the primary users. Receiving vessel crews, surveyors and port authorities also interact with the digital workflow. Every party in a bunkering transaction operates from the same verified record, with role-appropriate access.
Is eBDN compliant with industry standards?
Yes. ZeroNorth eBDN is designed to align with regulatory and industry frameworks, including the standards set by the Maritime and Port Authority of Singapore for digital bunkering, ensuring secure, auditable and compliant documentation for every delivery.
Can eBDN data flow automatically into our procurement system and trigger payment processes?
Yes. ZeroNorth eBDN transfers delivery data directly into procurement systems upon completion, automatically matching deliveries against the corresponding supplier orders and initiating payment processes without manual intervention. This removes the manual data entry step that causes most reconciliation errors and accelerates settlement cycles.
