BW FRIGG against its type
Built in 2016, it is 3 years newer than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 47,384 gross tonnage it is larger than 83% of the other 525 gas carriers with a recorded tonnage. It is one of 70 gas carriers here under the Marshall Islands flag, 10.2% of the 688 on the register. The same builder is recorded for 761 other vessels here, 100 of them gas carriers. The returns for 2018–2025 all give Majuro as port of registry.
Its 3,974 t of CO₂ for 2025 is 33% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 355.8 kg CO₂, 39% above the type median of 256.2 kg. It logged 796 hours at sea against a median of 1,943 hours for its type that year. 1.9% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 5 years with reported emissions, the highest was 2021 (6,427 t) and the lowest 2022 (1,969 t). Its efficiency percentile within the type went from 2 in 2018 to 16 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 46 of 292 qualifying gas carriers by EEOI, at the 16th percentile. The dashed line is the type median, 27.9; this vessel reported 15.2.
EEOI divides emissions by transport work, which for this vessel and year was 262,333,333 tonne-miles over 11,170 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 94.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2024, so the series has gaps.
From 2023 to 2025, emissions fell 11.1% while distance sailed fell 14.7%and CO₂ per nautical mile rose 4.2%.That points mainly to how much the vessel sailed, rather than the other.
