Determine whether an alternative-fuel vessel announcement represents a usable transition pathway or stranded optionality.
A dual-fuel vessel is an option on a fuel chain, not proof that the chain exists at commercial scale. Maersk's 2023 annual report records a bounded case: the 2,100-TEU Laura Mærsk completed its first voyage on green methanol and entered Baltic feeder service [1]. The same document reported a larger vessel order book, but orders do not establish future fuel volume. The IMO's 2024 lifecycle guidelines require attention to feedstock, production pathway, transport, bunkering and onboard use [2]. FuelEU Maritime adds a compliance context for greenhouse-gas intensity rather than declaring any engine or fuel label automatically compliant [3].
Compare two linked assets
Build separate records for the vessel and the fuel pathway. The vessel record covers delivery date, engine modes, tank constraints, range, retrofitability, charter terms and fallback fuel. The pathway record covers feedstock, conversion technology, plant status, certification, annual contracted volume, delivery window, bunker ports, storage, price formula and lifecycle intensity. Link them by route and time. A capable engine without compatible bunkering is underused capital; fuel without a committed fleet is demand risk.
Do not collapse 'methanol-capable,' 'methanol-fuelled' and 'lower lifecycle intensity.' The IMO framework separates well-to-tank from tank-to-wake emissions and defines a Fuel Lifecycle Label containing pathway information [2]. The same molecule can therefore carry different lifecycle results depending on feedstock, production energy, transport and verification. Record the actual pathway or mark it unknown.
- Asset proof: delivered, classed, commissioned and route-assigned.
- Input proof: named producer, pathway, volume, start date and certification.
- Logistics proof: bunker port, storage, handling and fallback procedure.
- Commercial proof: price basis, take-or-pay terms and shortage allocation.
Use a coverage ratio, not a vessel count
For each period, divide contracted usable fuel energy by the fleet's expected energy requirement on named services. Apply delivery probability and route accessibility separately. Do not count memoranda of understanding as firm volume. Show an uncontracted gap and a conventional-fuel fallback case. Regulation (EU) 2023/1805 establishes limits on the greenhouse-gas intensity of energy used on board and a verification structure [3]; it does not guarantee that a particular operator can procure a compliant fuel at a chosen port or price.
Worked example, explicitly hypothetical: four dual-fuel ships require 100 energy units annually. Signed contracts cover 55 units, but only 40 can reach their scheduled bunker ports; a new plant expected to supply 25 more units is not yet commissioned. The decision-grade coverage ratio is 40%, not 80%. If fallback fuel keeps the vessels operating, the asset may still be commercially useful, but the emissions and compliance case must use the fallback mix rather than the engine's theoretical capability.
Read the dated case correctly
Laura Mærsk is evidence that a container vessel completed one long delivery voyage on green methanol and then entered service in 2023 [1]. It is not evidence that every ordered vessel had secured lifetime supply, that all methanol pathways had equal lifecycle intensity, or that economics were competitive across routes. Use the case as a completed technical and logistics milestone, then ask what repeated supply evidence exists for the fleet and period under review.
Approve fleet expansion when route-level fuel coverage meets the operating threshold under a delayed-plant scenario, lifecycle evidence is verifiable, and fallback economics are tolerable. If only the vessel side is firm, describe the purchase as dual-fuel optionality. That wording keeps the asset decision separate from the transition outcome.
Take it into the meeting
- Maintain separate vessel and fuel-pathway ledgers.
- Calculate route-accessible contracted fuel coverage by period.
- Label an asset as optionality until its input chain is evidenced.
