FLEX RAINBOW against its type
Built in 2018, it is 4 years newer than the median LNG carrier on this register, which was built in 2014 (396 vessels with a known build year). At 115,174 gross tonnage it is larger than 68% 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 returns for 2018–2025 all give Majuro as port of registry.
Its 13,992 t of CO₂ for 2025 is 35% below the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 643.6 kg CO₂, 21% above the type median of 533.6 kg. It logged 1,596 hours at sea against a median of 2,940 hours for its type that year. 2.0% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 7 years with reported emissions, the highest was 2022 (54,972 t) and the lowest 2021 (5,157 t). Of the 6 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2018
Position 1 of 6 qualifying lng carriers by EEOI, at the 0th percentile. The dashed line is the type median, 26.2; this vessel reported 1.4.
EEOI divides emissions by transport work, which for this vessel and year was 5,004,934,307 tonne-miles over 38,658 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 104.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 22.4% and CO₂ per nautical mile fell 4.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
