MERSEY against its type
Built in 2019, it is 9 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,917 gross tonnage it is larger than 85% 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. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it ORPHEUS for 2019–2022 and MERSEY for 2023–2024. The returns for 2019–2024 all give Majuro as port of registry.
Its 2,731 t of CO₂ for 2024 is 53% 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 268.3 kg CO₂, close to the type median of 253.5 kg. It logged 1,005 hours at sea against a median of 2,177 hours for its type that year. 2.1% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 6 years with reported emissions, the highest was 2023 (9,597 t) and the lowest 2024 (2,731 t). Its efficiency percentile within the type went from 8 in 2019 to 57 in 2024 (lower is more efficient). The one sister ship listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2024
Position 678 of 1,194 qualifying chemical tankers by EEOI, at the 57th percentile. The dashed line is the type median, 15.9; this vessel reported 17.7.
EEOI divides emissions by transport work, which for this vessel and year was 154,481,335 tonne-miles over 10,179 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 9.4% lower than in 2019, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 71.5% while distance sailed fell 70.7%and CO₂ per nautical mile fell 2.8%.That points mainly to how much the vessel sailed, rather than the other.
