DNV Urges Gas Bunker Vessels to Fuel LNG Growth
A DNV white paper says the LNG bunker fleet must more than double by 2030 as LNG-fuelled ship numbers rise.
Updated on Nov. 6, 2026 in Cruises
DNV has published a white paper on gas bunker vessels to support the shift to alternative marine fuels. LNG is now the most widely adopted gaseous marine fuel, with around 900 LNG-fuelled vessels in operation worldwide.
Why it matters
Bunkering infrastructure is not keeping pace with rapid growth in LNG fuel demand from the fleet. Converting suitable small-scale LNG carriers into bunker vessels is presented as a practical way to accelerate capacity.
DNV's analysis, drawn from the LNG-fuelled fleet, shows around 900 vessels in operation worldwide excluding carriers, with about 650 more expected before 2030. The projections depend on fleet growth that is still unfolding, and the final bunker vessel count remains to be determined.
The players
DNV
DNV is an independent classification society and assurance provider that publishes maritime energy transition research and analysis.
The details
DNV's white paper examines how gas bunker vessels, which share many characteristics with conventional gas carriers, can support alternative fuel adoption. Successful conversion of LNG vessels requires vessel compatibility, ship-to-ship transfer arrangements, vapour and pressure management, and emergency response planning.
Timeline
November 6, 2026: DNV publishes the white paper on gas bunker vessels.
2020 to 2024: LNG consumption by LNG-fuelled vessels rose more than 500%.
2025 to 2030: LNG consumption is expected to grow a further 167%.
By 2030: The global LNG bunker vessel fleet may need to more than double.
Roadmap
The shift toward LNG as a marine fuel has moved faster than the supporting bunkering infrastructure, creating a capacity gap at sea. DNV's projections suggest the bunker vessel fleet will need to grow sharply to keep pace with fuel demand from the rising LNG-fuelled fleet.
Travelers booking cruises on LNG-fuelled ships may see fuel infrastructure shape which ports can refuel vessels efficiently. The gap in bunkering capacity described by DNV could influence itinerary and port-call planning as the fleet expands.
The takeaway
Fuel infrastructure is becoming as important as the ships themselves in the move to cleaner marine fuels. Watching bunkering capacity growth offers a useful signal of how quickly LNG-powered cruising can scale.
