DING HENG 38 against its type
Built in 2010, it is the same age as the median chemical tanker on this register (build year 2010, 1,951 vessels with a known build year). At 12,862 gross tonnage it is smaller than 65% 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 95 other vessels here, 6 of them chemical tankers. Its MRV returns name it STRAUM for 2019–2022 and DING HENG 38 for 2024–2025. The reported port of registry changed: Bergen (2019–2022), then MONROVIA (2024–2025).
Its 2,201 t of CO₂ for 2025 is 60% 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 295.3 kg CO₂, 18% above the type median of 250.2 kg. It logged 653 hours at sea against a median of 2,109 hours for its type that year. 2.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2021 (6,315 t) and the lowest 2024 (804 t). Its efficiency percentile within the type went from 80 in 2019 to 66 in 2022 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 61.0% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 173.9% and CO₂ per nautical mile fell 16.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
