The intelligence layer for bunkering

Most systems record the day. Bunker Agent steers it.

Nominations by email. ETA changes and delayed stems by WhatsApp. Port notices by the hour. Bunker Agent checks it all and turns it into a plan you can deliver.

Intelligent dispatch

Re-plan a disrupted day in seconds.

When a vessel runs late, a berth changes at the last minute or the weather turns, Bunker Agent weighs barge capacities, fuel grades, terminal slots, transit times and crew hours together and proposes the best available schedule. It shows exactly what has changed: which barge has changed hands, which stem has moved and what is now at risk. Your planner approves or declines it with one click.

The reality today

24/7 port operations, held together by spreadsheets and WhatsApp.

Bunkering is inherently dynamic. When an ETA slips or the weather turns, a spreadsheet can’t tell you what has changed, and your team spends hours rekeying nominations and chasing paperwork instead of directing the fleet.

How it fits

Works alongside the systems you already run.

Bunker Agent reads from your inbox, systems, delivery records and AIS, and sends a plan back to your team. Nothing is migrated and nothing is retired – and if you have no systems yet, it can run the whole process.

Port conditions

Plans built around how each port works.

Port authority notices, weather, traffic and water levels feed straight into the plan. Here is one afternoon in Rotterdam.

Each change is proposed to your planner, or applied automatically within the controls you set. Example notices for illustration.

The assistant

Your operators’ right hand.

Ask about any stem, barge or claim. The assistant reads across schedules, contracts, BDNs and email threads, including the PDFs nested inside them, and answers with its sources. It prepares the work. You decide how much it may do: routine steps run automatically, anything commercial waits for approval.

Built on a bunkering data model

Stems, grades, tolerances and laytime are defined in the model, so answers come from the same record your planners use.

Fluent in the trade

It understands nominations, surveyor reports and the shorthand of a bunker desk.

Tested against real cases

Every capability is measured against a library of real bunkering cases before it reaches your team.

The BDN shows 1,494 t delivered against 1,500 t nominated, a difference of 0.4%. The meter record agrees with the BDN to within 0.02%, and the contract allows ±0.5%, so the delivery is within terms.

The buyer’s surveyor used the ordered density rather than the loaded density. Their report is the PDF attached to a forwarded email from Tuesday.

The fuel transition

Methanol, LNG, ammonia and biofuels bring constraints your schedule never had to handle.

Different segregation rules, extended transfer durations, boil-off clocks that won't wait for a free berth. Bunker Agent models them alongside your existing grades, on the same schedule.

What it’s worth

The capacity of three more barges, without adding one.

Across a thirty-barge fleet, ten points of utilisation is the operating time of three barges. Today it is lost in waiting, repositioning and gaps between jobs. Delivery windows and crew rest stay where they are; the plan works around them.

Average transit per trip

Small gains, every day, on every barge. Modelled over a year: c.$250k per barge, and one more delivery a month from each.

Model it on your fleet

An illustrative day. Base case: thirty barges at 60–65% utilisation and $8/t contribution, no double counting. Rebuilt on your own fleet data in the assessment.

For a thirty-barge operation, that is $5–10m a year.

And that is the schedule alone. Fuel and crew hours, chartered tonnage, disputes and demurrage follow. Book a 30-minute working session and we'll model it on your fleet, your ports and your P&L.
