PTI HUANG HE 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 29,557 gross tonnage it is larger than 77% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The same builder is recorded for 180 other vessels here, 53 of them chemical tankers. Its MRV returns name it PTI HUANG HE for 2019–2022 and ARCHANGELOS MICHAEL for 2025. The reported port of registry changed: Hong Kong (2019–2022), then Monrovia (2025).
Its 7,353 t of CO₂ for 2025 is 33% 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 363.3 kg CO₂, 45% above the type median of 250.2 kg. It logged 2,135 hours at sea against a median of 2,109 hours for its type that year. 15.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2019 (11,201 t) and the lowest 2022 (2,809 t). Its efficiency percentile within the type went from 10 in 2019 to 51 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 692 of 1,348 qualifying chemical tankers by EEOI, at the 51st percentile. The dashed line is the type median, 14.4; this vessel reported 14.8.
EEOI divides emissions by transport work, which for this vessel and year was 498,541,017 tonne-miles over 20,242 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 34.3% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions rose 161.8% while distance sailed rose 103.8%and CO₂ per nautical mile rose 28.5%.That points mainly to how much the vessel sailed, rather than the other.
