ARDMORE CHIPPEWA 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 15,591 gross tonnage it is smaller than 62% 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 52 other vessels here, 48 of them chemical tankers. The returns for 2018–2025 all give Majuro as port of registry.

Its 7,855 t of CO₂ for 2025 is 42% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 232.5 kg CO₂, close to the type median of 250.2 kg. It logged 2,931 hours at sea against a median of 2,109 hours for its type that year. 8.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2024 (8,442 t) and the lowest 2021 (1,765 t). Its efficiency percentile within the type went from 60 in 2018 to 50 in 2025 (lower is more efficient). Of the 6 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 670 of 1,348 qualifying chemical tankers by EEOI, at the 50th percentile. The dashed line is the type median, 14.4; this vessel reported 14.3.

EEOI divides emissions by transport work, which for this vessel and year was 547,799,860 tonne-miles over 33,791 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 188.8% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.

From 2024 to 2025, emissions fell 6.9% while distance sailed fell 4.8%and CO₂ per nautical mile fell 2.3%.That points mainly to how much the vessel sailed, rather than the other.
