HAFNIA ANDROMEDA against its type
Built in 2011, it is 1 year newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,241 gross tonnage it is larger than 94% 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 192 other vessels here, 87 of them chemical tankers. Its MRV returns name it HAFNIA ANDROMEDA for 2018–2024 and MONARCH for 2025. The reported port of registry changed: Valletta (2018–2024), then Majuro (2025).
Its 1,611 t of CO₂ for 2025 is 71% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 345.7 kg CO₂, 38% above the type median of 250.2 kg. It logged 540 hours at sea against a median of 2,106 hours for its type that year. 9.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2019 (10,225 t) and the lowest 2025 (1,611 t). Its efficiency percentile within the type went from 24 in 2018 to 21 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 280 of 1,348 qualifying chemical tankers by EEOI, at the 21st percentile. The dashed line is the type median, 14.4; this vessel reported 9.2.
EEOI divides emissions by transport work, which for this vessel and year was 174,172,973 tonne-miles over 4,660 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 81.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 82.2% while distance sailed fell 83.5%and CO₂ per nautical mile rose 8.2%.That points mainly to how much the vessel sailed, rather than the other.
