BROOK against its type
Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 8,689 gross tonnage it is smaller than 84% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. Its MRV returns name it BROOK for 2020 and OWL 3 for 2021–2024. The returns for 2020–2024 all give Majuro as port of registry.
Its 2,266 t of CO₂ for 2024 is 61% 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 233.7 kg CO₂, close to the type median of 253.5 kg. It logged 908 hours at sea against a median of 2,177 hours for its type that year. 1.7% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 3 years with reported emissions, the highest was 2020 (2,343 t) and the lowest 2021 (2,117 t). The one comparable vessel listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2024
Position 990 of 1,194 qualifying chemical tankers by EEOI, at the 83rd percentile. The dashed line is the type median, 15.9; this vessel reported 32.0.
EEOI divides emissions by transport work, which for this vessel and year was 70,844,903 tonne-miles over 9,695 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 3.3% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2021 to 2024, emissions rose 7.0% and CO₂ per nautical mile rose 15.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
