CHEMBULK SINGAPORE against its type
Built in 2007, it is 3 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,534 gross tonnage it is smaller than 78% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 15 chemical tankers here under the South Korea flag, 0.6% of the 2,344 on the register. The same builder is recorded for 76 other vessels here, 58 of them chemical tankers. Its MRV returns name it CHEMBULK SINGAPORE for 2019 and DS OCEAN for 2024–2025. The reported port of registry changed: Majuro (2019), then Jeju (2024–2025).
Its 2,844 t of CO₂ for 2024 is 51% below the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 232.8 kg CO₂, close to the type median of 253.5 kg. It logged 1,050 hours at sea against a median of 2,177 hours for its type that year. 6.6% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Its efficiency percentile within the type went from 48 in 2019 to 49 in 2024 (lower is more efficient). Of the 3 sister ships listed below with a 2024 return, 1 reported a lower CO₂ per nautical mile than this vessel.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024
Position 583 of 1,194 qualifying chemical tankers by EEOI, at the 49th percentile. The dashed line is the type median, 15.9; this vessel reported 15.6.
EEOI divides emissions by transport work, which for this vessel and year was 182,171,044 tonne-miles over 12,213 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 42.6% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2023, so the series has gaps.
From 2019 to 2024, emissions fell 42.6% while distance sailed fell 31.4%and CO₂ per nautical mile fell 16.3%.That points mainly to how much the vessel sailed, rather than the other.
