ARCHON against its type

Built in 2016, it is 6 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,770 gross tonnage it is larger than 83% 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. Its MRV returns name it ARCHON for 2018–2021 and CATHERINE GRACE for 2022–2025. The returns for 2022–2025 all give Majuro as port of registry.

Its 5,955 t of CO₂ for 2025 is close to the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 265.1 kg CO₂, close to the type median of 250.2 kg. It logged 1,872 hours at sea against a median of 2,106 hours for its type that year. 8.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2020 (8,026 t) and the lowest 2023 (1,006 t). Its efficiency percentile within the type was 8 in both 2018 and 2025. Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 104 of 1,348 qualifying chemical tankers by EEOI, at the 8th percentile. The dashed line is the type median, 14.4; this vessel reported 7.6.

Reported CO₂ in 2025 was 39.5% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 312.0% while distance sailed rose 290.8%and CO₂ per nautical mile rose 5.4%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 8 MRV reporting years, an efficiency ranking, 4 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.
