CHEM SEA 1 against its type
Built in 2016, it is 6 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 16,084 gross tonnage it is smaller than 61% 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 NAVIG8 SIRIUS for 2018 and CHEM SEA 1 for 2023. The reported port of registry changed: Majuro (2018), then Madeira (2023).
Its 2,244 t of CO₂ for 2023 is 58% below the median of 5,393 t among the 1,411 chemical tankers on this register that reported for 2023. Per nautical mile it emitted 243.3 kg CO₂, close to the type median of 258.0 kg. It logged 774 hours at sea against a median of 1,919 hours for its type that year. 11.1% of its 2023 emissions were at berth; the median for chemical tankers was 8.2%. Its efficiency percentile within the type went from 40 in 2018 to 30 in 2023 (lower is more efficient). The one comparable vessel listed below with a 2023 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2023
Position 370 of 1,230 qualifying chemical tankers by EEOI, at the 30th percentile. The dashed line is the type median, 15.6; this vessel reported 12.2.
EEOI divides emissions by transport work, which for this vessel and year was 183,475,879 tonne-miles over 9,223 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 60.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, so the series has gaps.
From 2018 to 2023, emissions fell 60.0% while distance sailed fell 67.3%and CO₂ per nautical mile rose 22.3%.That points mainly to how much the vessel sailed, rather than the other.
