HAFNIA AMETHYST 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 474 chemical tankers here under the Marshall Islands flag, 20.2% 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 AMETHYST for 2018–2021 and HAFNIA AMETHYST for 2022–2025. The returns for 2018–2025 all give Majuro as port of registry.

Its 6,923 t of CO₂ for 2025 is 25% 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 245.6 kg CO₂, close to the type median of 250.2 kg. It logged 2,778 hours at sea against a median of 2,106 hours for its type that year. 2.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2021 (8,257 t) and the lowest 2022 (2,389 t). Its efficiency percentile within the type went from 12 in 2018 to 23 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 316 of 1,348 qualifying chemical tankers by EEOI, at the 23rd percentile. The dashed line is the type median, 14.4; this vessel reported 9.8.

0255075100more efficientless efficientThis vessel: 23rd percentile, EEOI 9.8

EEOI divides emissions by transport work, which for this vessel and year was 710,078,974 tonne-miles over 28,195 nautical miles.

Reported CO₂ in 2025 was 104.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2024, so the series has gaps.

From 2023 to 2025, emissions rose 11.9% while distance sailed rose 17.8%and CO₂ per nautical mile fell 5.0%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 6 MRV reporting years, an efficiency ranking, 5 of 5 vessel particulars and a name history. Not found in the sources for this vessel: AIS movements in Norwegian waters, a licensed photograph, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
