FLEX ENDEAVOUR 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 113,049 gross tonnage it is larger than 53% 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 660 other vessels here, 109 of them LNG carriers. The reported port of registry changed: Valletta (2018–2021), then Majuro (2022–2025).

Its 38,134 t of CO₂ for 2025 is 1.8 times the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 553.6 kg CO₂, close to the type median of 533.6 kg. It logged 4,446 hours at sea against a median of 2,940 hours for its type that year. 1.2% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 7 years with reported emissions, the highest was 2025 (38,134 t) and the lowest 2024 (6,591 t). Of the 8 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2018

Position 2 of 6 qualifying lng carriers by EEOI, at the 20th percentile. The dashed line is the type median, 26.2; this vessel reported 11.8.

EEOI divides emissions by transport work, which for this vessel and year was 2,703,714,164 tonne-miles over 60,000 nautical miles.

Reported CO₂ in 2025 was 19.6% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.

From 2024 to 2025, emissions rose 478.6% and CO₂ per nautical mile fell 24.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
