SEAWAYS GATUN against its type
Built in 2007, it is 3 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 27,916 gross tonnage it is larger than 65% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 95 chemical tankers here under the Norway flag, 4.1% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it SEAWAYS GATUN for 2022–2023 and CHAMPION POLAR for 2025. The reported port of registry changed: Monrovia (2022–2023), then Bergen (2025).
Its 7,617 t of CO₂ for 2025 is 38% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 321.7 kg CO₂, 29% above the type median of 250.2 kg. It logged 1,961 hours at sea against a median of 2,106 hours for its type that year. 10.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2025 (7,617 t) and the lowest 2022 (1,702 t). Its efficiency percentile within the type went from 88 in 2023 to 25 in 2025 (lower is more efficient). Of the 4 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 336 of 1,348 qualifying chemical tankers by EEOI, at the 25th percentile. The dashed line is the type median, 14.4; this vessel reported 10.2.
EEOI divides emissions by transport work, which for this vessel and year was 750,476,847 tonne-miles over 23,679 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 347.6% higher than in 2022, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 165.3% while distance sailed rose 178.7%and CO₂ per nautical mile fell 4.8%.That points mainly to how much the vessel sailed, rather than the other.
