LUCKY CHEMIST against its type
Built in 2015, it is 5 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,735 gross tonnage it is larger than 82% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. The same builder is recorded for 180 other vessels here, 53 of them chemical tankers. Its MRV returns name it STI TRIBECA for 2018–2022 and LUCKY CHEMIST for 2025. The reported port of registry changed: Majuro (2018–2022), then Panama (2025).
Its 7,699 t of CO₂ for 2025 is 39% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 263.6 kg CO₂, close to the type median of 250.2 kg. It logged 2,507 hours at sea against a median of 2,109 hours for its type that year. 6.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2019 (8,058 t) and the lowest 2022 (3,698 t). Its efficiency percentile within the type went from 2 in 2018 to 4 in 2025 (lower is more efficient). Of the 4 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 52 of 1,348 qualifying chemical tankers by EEOI, at the 4th percentile. The dashed line is the type median, 14.4; this vessel reported 6.9.
EEOI divides emissions by transport work, which for this vessel and year was 1,114,115,774 tonne-miles over 29,206 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 63.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions rose 108.2% while distance sailed rose 109.0%and CO₂ per nautical mile fell 0.4%.That points mainly to how much the vessel sailed, rather than the other.
