ARDMORE PURPOSE against its type

Built in 2020, it is 10 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,087 gross tonnage it is larger than 92% 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 563 other vessels here, 2 of them chemical tankers. Its MRV returns name it GWN 2 for 2020–2021, NORDTOKYO for 2022–2024 and ARDMORE PURPOSE for 2025. The reported port of registry changed: MONROVIA (2020), then Singapore (2021), then MADEIRA (2022–2024), then Majuro (2025).

Its 4,745 t of CO₂ for 2025 is 14% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 291.1 kg CO₂, 16% above the type median of 250.2 kg. It logged 1,663 hours at sea against a median of 2,109 hours for its type that year. 15.5% 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 (9,864 t) and the lowest 2023 (354 t). Its efficiency percentile within the type went from 43 in 2020 to 65 in 2024 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 6.9% higher than in 2020, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 118.6% and CO₂ per nautical mile rose 23.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 6 MRV reporting years, 5 of 5 vessel particulars and a name history. Not found in the sources for this vessel: an efficiency ranking, 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.
