DING HENG 39 against its type
Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,722 gross tonnage it is smaller than 74% 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 52 other vessels here, 48 of them chemical tankers. Its MRV returns name it DREGGEN for 2018–2022 and DING HENG 39 for 2024–2025. The reported port of registry changed: George Town (2018–2021), then BERGEN (2022), then Monrovia (2024–2025).
Its 1,952 t of CO₂ for 2025 is 65% 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 233.9 kg CO₂, close to the type median of 250.2 kg. It logged 701 hours at sea against a median of 2,109 hours for its type that year. 4.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2019 (10,611 t) and the lowest 2021 (394 t). Its efficiency percentile within the type went from 80 in 2018 to 54 in 2024 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 645 of 1,194 qualifying chemical tankers by EEOI, at the 54th percentile. The dashed line is the type median, 15.9; this vessel reported 17.2.
EEOI divides emissions by transport work, which for this vessel and year was 433,350,816 tonne-miles over 32,301 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 7.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 73.8% and CO₂ per nautical mile rose 1.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
