SEYMOUR SUN against its type
Built in 2022, it is 12 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,873 gross tonnage it is larger than 97% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 205 chemical tankers here under the Singapore flag, 8.7% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. The returns for 2022–2025 all give SINGAPORE as port of registry.
Its 4,861 t of CO₂ for 2025 is 12% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 217.9 kg CO₂, 13% below the type median of 250.2 kg. It logged 2,092 hours at sea against a median of 2,106 hours for its type that year. 5.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2022 (11,801 t) and the lowest 2025 (4,861 t). Its efficiency percentile within the type went from 37 in 2022 to 30 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 398 of 1,348 qualifying chemical tankers by EEOI, at the 30th percentile. The dashed line is the type median, 14.4; this vessel reported 10.9.
EEOI divides emissions by transport work, which for this vessel and year was 446,003,670 tonne-miles over 22,314 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 58.8% lower than in 2022, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 37.5% and CO₂ per nautical mile fell 12.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
