CLEAROCEAN MARIGOLD against its type
Built in 2014, it is 4 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,705 gross tonnage it is larger than 81% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 205 chemical tankers here under the Singapore flag, 8.7% of the 2,344 on the register. Its MRV returns name it CLEAROCEAN MARY for 2018–2023 and CLEAROCEAN MARIGOLD for 2025. The reported port of registry changed: Monrovia (2018–2023), then SINGAPORE (2025).
Its 3,559 t of CO₂ for 2025 is 36% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 251.4 kg CO₂, close to the type median of 250.2 kg. It logged 1,209 hours at sea against a median of 2,106 hours for its type that year. 2.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2018 (6,908 t) and the lowest 2023 (3,531 t). Its efficiency percentile within the type went from 69 in 2018 to 25 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 345 of 1,348 qualifying chemical tankers by EEOI, at the 25th percentile. The dashed line is the type median, 14.4; this vessel reported 10.2.
EEOI divides emissions by transport work, which for this vessel and year was 347,566,406 tonne-miles over 14,155 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 48.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 0.8% while distance sailed rose 14.8%and CO₂ per nautical mile fell 12.2%.
