PURPLE RAY against its type
It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The returns for 2020–2025 all give Monrovia as port of registry.
Its 4,818 t of CO₂ for 2025 is 13% 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 150.9 kg CO₂, 40% below the type median of 250.2 kg. It logged 2,512 hours at sea against a median of 2,106 hours for its type that year. 3.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2024 (7,208 t) and the lowest 2025 (4,818 t). Its efficiency percentile within the type went from 24 in 2020 to 23 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
