Methanol-fuelled ships
The leading 2024–2028 alternative-fuel choice for container fleets. Why it's winning the order book, what's different in the engine room, and what crews need to know.
What it is
Methanol (CH₃OH) burned in dual-fuel diesel or modified Otto-cycle engines. Liquid at ambient temperature + pressure (no cryogenics), simpler bunkering than LNG, lower-toxicity than ammonia. Green methanol produced from biomass or captured CO₂ + renewable hydrogen.
Why it matters
Maersk has bet the container fleet on methanol; ~250 vessels on order across the industry. The fleet is delivering now (Laura Maersk + sister ships). Engineer + officer demand for methanol-experienced crew is already exceeding supply on Maersk + other operators.
Where it stands in 2026
~50 vessels in service, ~250 on order. Bunkering at Singapore, Rotterdam, Ulsan, Yokohama. STCW Reg V/3 (IGF Code) + emerging methanol-specific endorsements. Maersk + COSCO + CMA CGM + Evergreen all have methanol-fleet programmes.
Training implications
- STCW Reg V/3 (IGF Code) — required for engineers + officers on low-flashpoint-fuelled vessels.
- Operator-specific methanol training (combustion, leak response, fire fighting).
- Methanol fire-fighting drills (invisible flame, low temperature — different from HFO fires).
- Bunkering procedure training for methanol delivery.
Safety risks
- Toxic + flammable (lower flash point than HFO).
- Invisible flame — methanol fires don't show on standard thermal cameras.
- Slip + fall risk on spilled methanol (low surface tension).
- Required PPE: alcohol-resistant gloves + face shield + impervious clothing.
Career angles
- Methanol-experienced engineers in scarce supply through 2027.
- Maersk's structured cadet → 3/E → 2/E pipeline on methanol vessels is a strong career path.
- Bunkering + terminal-supervisor demand growing at major hubs.
Common misunderstandings
- 'Methanol is just biofuel.' Methanol is a distinct molecule with its own engine + safety implications.
- 'It's a drop-in replacement.' Dual-fuel engines are needed; conversion costs are significant.
- 'Methanol fires are obvious.' The flame is nearly invisible — IR detection + foam suppression are critical.
