CHEM SCEPTRUM against its type
Built in 2017, it is 7 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 71 chemical tankers here under the Portugal flag, 3.0% of the 2,344 on the register. Its MRV returns name it NAVIG8 SCEPTRUM for 2018 and CHEM SCEPTRUM for 2024. The reported port of registry changed: Majuro (2018), then Madeira (2024).
Its 2,345 t of CO₂ for 2024 is 60% 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 240.7 kg CO₂, close to the type median of 253.5 kg. It logged 930 hours at sea against a median of 2,177 hours for its type that year. 10.8% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Its efficiency percentile within the type went from 44 in 2018 to 31 in 2024 (lower is more efficient).

Efficiency against its own type2024
Position 369 of 1,194 qualifying chemical tankers by EEOI, at the 31st percentile. The dashed line is the type median, 15.9; this vessel reported 11.7.
EEOI divides emissions by transport work, which for this vessel and year was 200,076,792 tonne-miles over 9,743 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 44.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, 2023, so the series has gaps.
From 2018 to 2024, emissions fell 44.4% while distance sailed fell 46.5%and CO₂ per nautical mile rose 3.9%.That points mainly to how much the vessel sailed, rather than the other.
