FLEX VIGILANT against its type
It is one of 111 LNG carriers here under the Marshall Islands flag, 20.6% of the 538 on the register. The returns for 2021–2025 all give Majuro as port of registry.
Its 40,477 t of CO₂ for 2025 is 1.9 times the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 463.7 kg CO₂, 13% below the type median of 533.6 kg. It logged 5,999 hours at sea against a median of 2,940 hours for its type that year. 1.3% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 5 years with reported emissions, the highest was 2025 (40,477 t) and the lowest 2023 (15,024 t). Of the 7 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.
