MARYCAM SWAN against its type
Built in 2009, it is 4 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 16,808 gross tonnage it is smaller than 67% 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 761 other vessels here, 100 of them gas carriers. Its MRV returns name it MARYCAM SWAN for 2018–2022 and TRAMMO MARYCAM for 2023–2025. The reported port of registry changed: panama (2018–2022), then SINGAPORE (2023–2025).
Its 8,610 t of CO₂ for 2025 is 44% above the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 225.3 kg CO₂, 12% below the type median of 256.2 kg. It logged 2,864 hours at sea against a median of 1,943 hours for its type that year. 3.1% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 8 years with reported emissions, the highest was 2022 (12,334 t) and the lowest 2024 (6,302 t). Its efficiency percentile within the type went from 45 in 2018 to 58 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 169 of 292 qualifying gas carriers by EEOI, at the 58th percentile. The dashed line is the type median, 27.9; this vessel reported 34.8.
EEOI divides emissions by transport work, which for this vessel and year was 247,762,014 tonne-miles over 38,209 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 30.9% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 36.6% and CO₂ per nautical mile fell 9.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
