ARDMORE SEAHAWK 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 29,737 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. The same builder is recorded for 180 other vessels here, 53 of them chemical tankers. The returns for 2018–2025 all give Majuro as port of registry.

Its 5,848 t of CO₂ for 2025 is close to the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 281.0 kg CO₂, 12% above the type median of 250.2 kg. It logged 1,957 hours at sea against a median of 2,109 hours for its type that year. 3.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2024 (9,706 t) and the lowest 2019 (3,077 t). Its efficiency percentile within the type went from 11 in 2018 to 24 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 330 of 1,348 qualifying chemical tankers by EEOI, at the 24th percentile. The dashed line is the type median, 14.4; this vessel reported 10.0.

EEOI divides emissions by transport work, which for this vessel and year was 582,473,108 tonne-miles over 20,810 nautical miles.

Reported CO₂ by year

2018: 7,103 t20187,1032019: 3,077 t20192022: 4,048 t20222023: 9,331 t20232024: 9,706 t20242025: 5,848 t20255,848

Reported CO₂ in 2025 was 17.7% lower 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 39.8% while distance sailed fell 40.8%and CO₂ per nautical mile rose 1.9%.That points mainly to how much the vessel sailed, rather than the other.
