MYKLEBUST against its type
Built in 2022, it is 9 years newer than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 26,614 gross tonnage it is larger than 58% of the other 525 gas carriers with a recorded tonnage. It is one of 131 gas carriers here under the Liberia flag, 19.0% of the 688 on the register. The same builder is recorded for 983 other vessels here, 64 of them gas carriers. The returns for 2022–2025 all give Monrovia as port of registry.
Its 14,357 t of CO₂ for 2025 is 2.4 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 248.3 kg CO₂, close to the type median of 256.2 kg. It logged 4,536 hours at sea against a median of 1,943 hours for its type that year. 6.9% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 4 years with reported emissions, the highest was 2024 (15,682 t) and the lowest 2022 (6,934 t). Its efficiency percentile within the type went from 21 in 2022 to 38 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 111 of 292 qualifying gas carriers by EEOI, at the 38th percentile. The dashed line is the type median, 27.9; this vessel reported 22.1.
EEOI divides emissions by transport work, which for this vessel and year was 650,523,335 tonne-miles over 57,826 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 107.1% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 8.5% while distance sailed fell 15.4%and CO₂ per nautical mile rose 8.2%.That points mainly to how much the vessel sailed, rather than the other.
