FLEX VOLUNTEER against its type
Built in 2021, it is 7 years newer than the median LNG carrier on this register, which was built in 2014 (396 vessels with a known build year). At 112,000 gross tonnage it is larger than 51% of the other 377 LNG carriers with a recorded tonnage. It is one of 111 LNG carriers here under the Marshall Islands flag, 20.6% of the 538 on the register. The same builder is recorded for 461 other vessels here, 19 of them LNG carriers. The returns for 2021–2025 all give MAJURO as port of registry.
Its 13,298 t of CO₂ for 2025 is 38% below the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 547.4 kg CO₂, close to the type median of 533.6 kg. It logged 1,781 hours at sea against a median of 2,940 hours for its type that year. 1.5% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 5 years with reported emissions, the highest was 2023 (28,120 t) and the lowest 2024 (10,665 t). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 15.2% lower than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 24.7% and CO₂ per nautical mile rose 15.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
