STOLT PERSEVERANCE against its type
Built in 2001, it is 9 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 25,196 gross tonnage it is larger than 59% 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 9 other vessels here, one of them a chemical tanker. The returns for 2021–2025 all give George Town as port of registry.
Its 7,591 t of CO₂ for 2025 is 37% 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 366.1 kg CO₂, 46% above the type median of 250.2 kg. It logged 1,700 hours at sea against a median of 2,106 hours for its type that year. 10.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2019 (10,057 t) and the lowest 2021 (3,076 t). Its efficiency percentile within the type went from 47 in 2018 to 75 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025
Position 1,011 of 1,348 qualifying chemical tankers by EEOI, at the 75th percentile. The dashed line is the type median, 14.4; this vessel reported 23.1.
EEOI divides emissions by transport work, which for this vessel and year was 329,321,041 tonne-miles over 20,735 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 19.7% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 82.5% while distance sailed rose 122.7%and CO₂ per nautical mile fell 18.0%.That points mainly to how much the vessel sailed, rather than the other.
