HAFNIA AMESSI 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 23,676 gross tonnage it is larger than 54% 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 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it NAVIG8 AMESSI for 2018–2021 and HAFNIA AMESSI for 2022–2025. The reported port of registry changed: Majuro (2018–2022), then SINGAPORE (2023–2025).

Its 6,304 t of CO₂ for 2025 is 14% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 239.2 kg CO₂, close to the type median of 250.2 kg. It logged 2,217 hours at sea against a median of 2,106 hours for its type that year. 5.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2022 (11,531 t) and the lowest 2023 (1,899 t). Its efficiency percentile within the type went from 22 in 2018 to 62 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 832 of 1,348 qualifying chemical tankers by EEOI, at the 62nd percentile. The dashed line is the type median, 14.4; this vessel reported 17.6.

0255075100more efficientless efficientThis vessel: 62nd percentile, EEOI 17.6

EEOI divides emissions by transport work, which for this vessel and year was 358,796,244 tonne-miles over 26,355 nautical miles.

Reported CO₂ in 2025 was 13.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.

From 2023 to 2025, emissions rose 232.0% while distance sailed rose 243.6%and CO₂ per nautical mile fell 3.4%.That points mainly to how much the vessel sailed, rather than the other.
