CLIPPER HELEN against its type
Built in 2007, it is 6 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 13,893 gross tonnage it is smaller than 70% of the other 525 gas carriers with a recorded tonnage. It is one of 106 gas carriers here under the Singapore flag, 15.4% of the 688 on the register. The same builder is recorded for 65 other vessels here, 10 of them gas carriers. Its MRV returns name it CLIPPER HELEN for 2018–2021 and SANMAR RAGA for 2024–2025. The reported port of registry changed: Stavanger (2018–2021), then SINGAPORE (2024–2025).
Its 9,297 t of CO₂ for 2025 is 1.6 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 244.0 kg CO₂, close to the type median of 256.2 kg. It logged 2,697 hours at sea against a median of 1,943 hours for its type that year. 6.8% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 6 years with reported emissions, the highest was 2020 (20,723 t) and the lowest 2024 (244 t). Its efficiency percentile within the type went from 58 in 2018 to 85 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 248 of 292 qualifying gas carriers by EEOI, at the 85th percentile. The dashed line is the type median, 27.9; this vessel reported 80.0.
EEOI divides emissions by transport work, which for this vessel and year was 116,139,413 tonne-miles over 38,098 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 474.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 3,716.0% and CO₂ per nautical mile fell 1.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
