STOLT EFFORT against its type
Built in 1999, it is 11 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 24,509 gross tonnage it is larger than 57% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 48 chemical tankers here under the Cayman Islands flag, 2.0% of the 2,344 on the register. The same builder is recorded for 21 other vessels here, 6 of them chemical tankers. The returns for 2021–2025 all give George Town as port of registry.
Its 7,542 t of CO₂ for 2025 is 36% 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 424.2 kg CO₂, 1.7 times the type median of 250.2 kg. It logged 1,452 hours at sea against a median of 2,106 hours for its type that year. 17.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2018 (9,738 t) and the lowest 2023 (3,786 t). Its efficiency percentile within the type went from 61 in 2018 to 58 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 782 of 1,348 qualifying chemical tankers by EEOI, at the 58th percentile. The dashed line is the type median, 14.4; this vessel reported 16.4.
EEOI divides emissions by transport work, which for this vessel and year was 460,437,118 tonne-miles over 17,778 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 22.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.
From 2024 to 2025, emissions rose 25.2% while distance sailed rose 21.3%and CO₂ per nautical mile rose 3.2%.That points mainly to how much the vessel sailed, rather than the other.
