ALPINE MIA against its type

Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,266 gross tonnage it is larger than 69% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The same builder is recorded for 761 other vessels here, 4 of them chemical tankers. Its MRV returns name it ALPINE MIA for 2021–2022 and SEAWAYS MIA for 2024. The reported port of registry changed: Hong Kong (2021–2022), then MAJURO (2024).

Its 6,148 t of CO₂ for 2024 is close to the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 302.6 kg CO₂, 19% above the type median of 253.5 kg. It logged 1,586 hours at sea against a median of 2,177 hours for its type that year. 2.8% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Its efficiency percentile within the type went from 34 in 2021 to 17 in 2024 (lower is more efficient). Of the 2 comparable vessels listed below with a 2024 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024

Position 207 of 1,194 qualifying chemical tankers by EEOI, at the 17th percentile. The dashed line is the type median, 15.9; this vessel reported 9.5.

EEOI divides emissions by transport work, which for this vessel and year was 645,802,521 tonne-miles over 20,317 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2024 was 189.7% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.

From 2021 to 2024, emissions rose 189.7% while distance sailed rose 199.6%and CO₂ per nautical mile fell 3.3%.That points mainly to how much the vessel sailed, rather than the other.
