ARDMORE SEAVANGUARD against its type

Built in 2014, it is 4 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,030 gross tonnage it is larger than 91% 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 returns for 2018–2025 all give Majuro as port of registry.

Its 5,533 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 353.9 kg CO₂, 41% above the type median of 250.2 kg. It logged 1,266 hours at sea against a median of 2,106 hours for its type that year. 11.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2023 (10,711 t) and the lowest 2022 (3,158 t). Its efficiency percentile within the type went from 51 in 2018 to 33 in 2025 (lower is more efficient). The one comparable vessel listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025

Position 442 of 1,348 qualifying chemical tankers by EEOI, at the 33rd percentile. The dashed line is the type median, 14.4; this vessel reported 11.5.

EEOI divides emissions by transport work, which for this vessel and year was 481,132,174 tonne-miles over 15,635 nautical miles.

Reported CO₂ by year

2018: 8,011 t20188,0112021: 3,956 t20212022: 3,158 t20222023: 10,711 t20232024: 3,865 t20242025: 5,533 t20255,533

Reported CO₂ in 2025 was 30.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.

From 2024 to 2025, emissions rose 43.2% while distance sailed rose 13.5%and CO₂ per nautical mile rose 26.1%.That points mainly to how efficiently it sailed, rather than the other.

Sources and how to read this

This page draws on 6 MRV reporting years, an efficiency ranking, 4 of 5 vessel particulars and AIS movements in Norwegian waters. Not found in the sources for this vessel: a name history, 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.
