ALPINE MAYA against its type
Built in 2010, it is the same age as the median chemical tanker on this register (build year 2010, 1,951 vessels with a known build year). At 29,733 gross tonnage it is larger than 81% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 205 chemical tankers here under the Singapore flag, 8.7% of the 2,344 on the register. The same builder is recorded for 96 other vessels here, 31 of them chemical tankers. Its MRV returns name it ALPINE MAYA for 2018–2019 and GREAT MANTA for 2023. The reported port of registry changed: Hong Kong (2018–2019), then SINGAPORE (2023).
Its 2,238 t of CO₂ for 2023 is 59% below the median of 5,393 t among the 1,411 chemical tankers on this register that reported for 2023. Per nautical mile it emitted 310.0 kg CO₂, 20% above the type median of 258.0 kg. It logged 771 hours at sea against a median of 1,919 hours for its type that year. 7.0% of its 2023 emissions were at berth; the median for chemical tankers was 8.2%. Across 3 years with reported emissions, the highest was 2019 (5,093 t) and the lowest 2023 (2,238 t). Its efficiency percentile within the type went from 16 in 2018 to 22 in 2023 (lower is more efficient). The one comparable vessel listed below with a 2023 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2023
Position 265 of 1,230 qualifying chemical tankers by EEOI, at the 22nd percentile. The dashed line is the type median, 15.6; this vessel reported 10.7.
EEOI divides emissions by transport work, which for this vessel and year was 208,347,300 tonne-miles over 7,218 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 56.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2019 to 2023, emissions fell 56.1% while distance sailed fell 55.5%and CO₂ per nautical mile fell 1.2%.That points mainly to how much the vessel sailed, rather than the other.
