DORADO CHEM against its type
Built in 2005, it is 5 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 25,400 gross tonnage it is larger than 59% 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. Columbia Shipmanagement Ltd. is linked to 43 vessels on this register. Its MRV returns name it ROLLS I for 2019–2024 and DORADO CHEM for 2025. The reported port of registry changed: Panama (2019–2024), then Monrovia (2025).
Its 9,799 t of CO₂ for 2025 is 1.8 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 309.6 kg CO₂, 24% above the type median of 250.2 kg. It logged 3,048 hours at sea against a median of 2,109 hours for its type that year. 11.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2023 (10,746 t) and the lowest 2020 (1,734 t). Its efficiency percentile within the type went from 50 in 2019 to 64 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
