FuelEU Maritime compliance is the greenhouse gas intensity limit that ships calling at EU and EEA ports must meet on the energy they use on board, measured over a calendar year. For a bunker supplier, that turns every stem into a compliance decision the buyer makes before your barge arrives.

The regulation works on a **compliance balance**: a ship builds a surplus when the fuel it burns is cleaner than the limit and a deficit when it is dirtier. Pooling lets ships under one company, or across companies, share that balance. According to [Hellenic Shipping News](https://www.hellenicshippingnews.com/titan-analysis-shows-fueleu-pooling-propelled-liquefied-biomethane-demand/) (October 2026), Titan, part of Molgas, analysed the role of LNG, liquefied biomethane (LBM) and e-methane in FuelEU compliance and how the pooling mechanism has performed so far, modelling an 8,000 TEU containership on a Rotterdam, Antwerp, Hamburg and Algeciras rotation.

## Why pooling changes what a buyer asks you for

Pooling turns a fuel decision into a portfolio decision. A ship with a deficit can be balanced by a sister vessel with a surplus, so the buyer is no longer shopping only for the cheapest grade at your port.

That buyer now asks two questions in the same enquiry: what can you deliver alongside the berth window, and what compliance value does it carry. A supplier who answers both in one quote is easier to shortlist than one who sends a price and waits for a follow-up call.

- **Grade and GHG intensity** of the delivered fuel, not just the grade name
- **Volume** that lets the buyer plan a balance across a rotation rather than a single stem
- **Timing** against the ETA, because a compliance-driven stem is often less flexible than a routine one

## The fuel mix is widening at the same ports

Bunker menus are broadening faster than most suppliers' quotation templates. According to [Hellenic Shipping News](https://www.hellenicshippingnews.com/the-week-in-alt-fuels-building-the-bunker-menu/) (October 2026), China's Ningbo-Zhoushan port saw three bunker vessels supply LNG, methanol and B24 biofuel on 30 September, and the same week brought biofuels, LBM, methanol, ethanol and ammonia activity across several major ports.

Green ammonia is moving from pilot to commercial operation. On 13 October 2026, Shenghang Yongle supplied 1,000 tonnes of green ammonia to Mineral Europa, an ammonia-powered vessel owned by CMB.TECH, in what [Hellenic Shipping News](https://www.hellenicshippingnews.com/worlds-first-commercial-ship-to-ship-green-ammonia-bunkering-completed-in-china/) (October 2026) reports as the first commercial ship-to-ship green ammonia bunkering. [Marine Insight](https://www.marineinsight.com/worlds-first-ship-to-ship-green-ammonia-bunkering-achieved-in-chinas-zhoushan-port/?utm_source=rss&utm_medium=rss&utm_campaign=worlds-first-ship-to-ship-green-ammonia-bunkering-achieved-in-chinas-zhoushan-port) (October 2026) places the transfer at Zhoushan.

CMB.TECH's chief technology officer, Roy Campe, told ENGINE that third-party demand, beyond the company's own fleet, will underpin the commercial viability of its Walvis Bay ammonia bunkering terminal, with the fleet planned to reach 21 ammonia-capable vessels by 2029, per [Hellenic Shipping News](https://www.hellenicshippingnews.com/future-fuel-talks-ammonia-bunkering-needs-customers-beyond-early-adopters-cmb-tech/) (October 2026). Read that as a sales signal: the alternative fuel buyer is not always the ship you see on AIS.

## What compliance costs do to the fuel decision

Fuel is the largest controllable line in a voyage budget, which is why compliance-driven fuel choices reach the purchasing desk so quickly. A 2023 study in the *Journal of Marine Science and Engineering* notes that fuel consumption already makes up 45-55% of a ship's total operational cost, and that bunker procurement and operational consumption are usually managed as two isolated strategies ([MDPI](https://doi.org/10.3390/jmse11050894)).

FuelEU pushes those two strategies together. A purchasing superintendent weighing a bio-blend against VLSFO is now modelling the vessel's year-end balance at the same time as the stem price, and the supplier who frames the quote that way saves the buyer a step.

## Port calls still set the clock

Compliance planning does not relax the berth window. Gibraltar recorded 477 bunker calls in September 2026, up 11% from 431 a year earlier, according to Gibraltar Port Authority data reported by [Hellenic Shipping News](https://www.hellenicshippingnews.com/gibraltar-sees-busiest-september-for-bunker-calls-since-2021/) (October 2026).

Lead times are stretching elsewhere. ENGINE reported for [Hellenic Shipping News](https://www.hellenicshippingnews.com/engine-east-of-suez-bunker-fuel-availability-outlook-206/) (October 2026) that Singapore suppliers recommend 12-15 days' notice for VLSFO, with HSFO expected to stay tight into November. In Northwest Europe, [ENGINE](https://www.hellenicshippingnews.com/engine-europe-africa-bunker-fuel-availability-outlook-204/) (October 2026) reported tight prompt supply in the ARA ports and advised 5-7 days to gather competitive offers.

A compliance-motivated enquiry that arrives after the vessel has sailed is a lost stem. The supplier who reaches the technical manager or purchasing superintendent while the ship is still on passage has the time to build a compliant, deliverable offer.

## A quoting routine for a compliance-driven stem

1. **Confirm the vessel's FuelEU position early.** Ask whether the stem is routine or balance-driven, and which grade carries the compliance value.
2. **Quote grade, GHG intensity, volume and delivery window together.** One message, not four emails.
3. **Name the decision-maker.** Compliance questions usually sit with technical managers, fleet teams and purchasing superintendents, not only the chartering desk.
4. **Follow up on a schedule.** A balance-driven decision often waits for a head-office review, so a structured follow-up beats a single chase.

VesselReach supports this by detecting vessels near your target ports and those scheduled to arrive, identifying the company behind each vessel, and finding the operations, technical, procurement and C-suite contacts by role. That means your quote reaches the purchasing superintendent before the berth window opens. See VesselReach for bunker suppliers.

## How VesselReach helps

FuelEU enquiries reward suppliers who reach the right desk before the vessel arrives. VesselReach turns vessel movements into those conversations.

- **Pre-arrival vessel intelligence:** VesselReach shows vessels near your selected ports and expected arrivals, which means you can open a compliance conversation while the ship is still on passage.
**Decision-maker discovery by role:** VesselReach finds operations, technical, procurement and C-suite contacts behind each vessel, which means your quote lands with the person who owns the fuel decision.
- **Staged email, WhatsApp and phone outreach with automated follow-ups:** VesselReach keeps a balance-driven enquiry moving through a head-office review, which means fewer stems lost to silence.

## Frequently asked questions

### What is FuelEU Maritime compliance in simple terms?

FuelEU Maritime sets a greenhouse gas intensity limit for the energy ships use on voyages to, from and within EU and EEA ports, measured over a calendar year. A ship that beats the limit builds a surplus; one that misses it carries a deficit.

### How does FuelEU pooling affect a bunker enquiry?

Pooling lets ships share compliance balances, so a buyer may need a specific grade or volume to balance another vessel rather than the cheapest stem at your port. Titan's analysis of LNG, LBM and e-methane examined how pooling has performed so far. ([Hellenic Shipping News](https://www.hellenicshippingnews.com/titan-analysis-shows-fueleu-pooling-propelled-liquefied-biomethane-demand/))

### Which alternative fuels are actually being delivered at ports now?

LNG, methanol, B24 biofuel, LBM, ethanol and ammonia have all featured in recent port activity. Ningbo-Zhoushan saw LNG, methanol and B24 supplied on 30 September 2026, and Zhoushan hosted the first commercial ship-to-ship green ammonia bunkering in October 2026. ([Hellenic Shipping News](https://www.hellenicshippingnews.com/the-week-in-alt-fuels-building-the-bunker-menu/))

### How far ahead should a bunker supplier expect enquiries?

Lead times vary by port and grade. ENGINE reported Singapore suppliers recommending 12-15 days' notice for VLSFO in October 2026, while ARA buyers were advised to allow 5-7 days to collect competitive offers. ([Hellenic Shipping News](https://www.hellenicshippingnews.com/engine-east-of-suez-bunker-fuel-availability-outlook-206/))

### Who should a bunker supplier contact about a compliance-driven stem?

Compliance questions usually sit with technical managers, fleet teams and purchasing superintendents, alongside the chartering desk. VesselReach identifies these roles behind each vessel so your quote reaches the person who owns the fuel decision.

## More on this topic

FuelEU maritime compliance is easier to sell when you know what the buyer is measuring. The regulation compares a ship's greenhouse gas intensity with a yearly limit, and the difference is the compliance balance. Ships with a surplus can help ships with a deficit through pooling, so a bunker enquiry may be driven by a balance rather than by price alone. Titan's analysis of LNG, liquefied biomethane and e-methane showed how pooling has shaped demand so far. Suppliers who quote grade, intensity, volume and delivery window together, and who reach the technical or purchasing contact before the vessel berths, are the ones who win the stem.
