ALKIVIADIS against its type
Built in 2006, it is 4 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 23,270 gross tonnage it is larger than 51% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 30 chemical tankers here under the Bahamas flag, 1.3% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it ALKIVIADIS for 2018–2020, SEAWAYS AMBROSE for 2021, CHEMTRANS MERCURY for 2022 and ASTON MARINE for 2025. The reported port of registry changed: MAJURO (2021), then Monrovia (2022), then NASSAU (2025).
Its 12,716 t of CO₂ for 2022 is 2.2 times the median of 5,807 t among the 1,486 chemical tankers on this register that reported for 2022. Per nautical mile it emitted 318.9 kg CO₂, 20% above the type median of 266.3 kg. It logged 3,576 hours at sea against a median of 1,995 hours for its type that year. 16.4% of its 2022 emissions were at berth; the median for chemical tankers was 8.6%. Across 5 years with reported emissions, the highest was 2018 (17,465 t) and the lowest 2021 (10,063 t). Its efficiency percentile within the type went from 56 in 2018 to 62 in 2022 (lower is more efficient). The one sister ship listed below with a 2022 return reported a lower CO₂ per nautical mile.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2022
Position 822 of 1,334 qualifying chemical tankers by EEOI, at the 62nd percentile. The dashed line is the type median, 15.7; this vessel reported 18.8.
EEOI divides emissions by transport work, which for this vessel and year was 675,328,731 tonne-miles over 39,873 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 27.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2021 to 2022, emissions rose 26.4% while distance sailed rose 46.6%and CO₂ per nautical mile fell 13.8%.That points mainly to how much the vessel sailed, rather than the other.
