STOLT SEA 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 14,900 gross tonnage it is smaller than 63% 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 7 other vessels here. The returns for 2021–2024 all give George Town as port of registry.

Its 3,360 t of CO₂ for 2024 is 42% below the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 267.2 kg CO₂, close to the type median of 253.5 kg. It logged 998 hours at sea against a median of 2,177 hours for its type that year. 2.1% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 6 years with reported emissions, the highest was 2018 (14,033 t) and the lowest 2024 (3,360 t). Its efficiency percentile within the type went from 71 in 2018 to 66 in 2024 (lower is more efficient). Of the 3 comparable vessels listed below with a 2024 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024

Position 782 of 1,194 qualifying chemical tankers by EEOI, at the 66th percentile. The dashed line is the type median, 15.9; this vessel reported 20.7.

EEOI divides emissions by transport work, which for this vessel and year was 162,319,807 tonne-miles over 12,573 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2024 was 76.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.

From 2022 to 2024, emissions fell 33.6% while distance sailed fell 25.5%and CO₂ per nautical mile fell 10.8%.That points mainly to how much the vessel sailed, rather than the other.
