CHALLENGE PRIME against its type
Built in 2017, it is 7 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,267 gross tonnage it is larger than 70% 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 returns for 2018–2025 all give SINGAPORE as port of registry.
Its 6,334 t of CO₂ for 2025 is 15% 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 276.6 kg CO₂, 11% above the type median of 250.2 kg. It logged 2,077 hours at sea against a median of 2,106 hours for its type that year. 8.7% 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 (6,334 t) and the lowest 2023 (1,545 t). Its efficiency percentile within the type went from 18 in 2018 to 8 in 2025 (lower is more efficient). Of the 2 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 106 of 1,348 qualifying chemical tankers by EEOI, at the 8th percentile. The dashed line is the type median, 14.4; this vessel reported 7.7.
EEOI divides emissions by transport work, which for this vessel and year was 828,007,843 tonne-miles over 22,902 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 118.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, 2024, so the series has gaps.
From 2023 to 2025, emissions rose 309.9% while distance sailed rose 238.4%and CO₂ per nautical mile rose 21.1%.That points mainly to how much the vessel sailed, rather than the other.
