CHEMTRANS NAOS against its type
Built in 2006, it is 4 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 41,583 gross tonnage it is smaller than 65% of the other 2,841 oil tankers with a recorded tonnage. It is one of 29 oil tankers here under the Cyprus flag, 0.8% of the 3,548 on the register. The same builder is recorded for 146 other vessels here, 55 of them oil tankers. Its MRV returns name it COMPASS for 2019, CHEMTRANS NAOS for 2022 and CHORA for 2023. The reported port of registry changed: Singapore (2019), then Limassol (2022), then MONROVIA (2023).
Its 7,527 t of CO₂ for 2023 is close to the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 421.7 kg CO₂, close to the type median of 408.5 kg. It logged 5,684 hours at sea against a median of 1,807 hours for its type that year. 13.6% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 3 years with reported emissions, the highest was 2023 (7,527 t) and the lowest 2022 (2,545 t). Its efficiency percentile within the type went from 79 in 2019 to 97 in 2023 (lower is more efficient). The one sister ship listed below with a 2023 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2023
Position 1,573 of 1,615 qualifying oil tankers by EEOI, at the 97th percentile. The dashed line is the type median, 8.0; this vessel reported 31.9.
EEOI divides emissions by transport work, which for this vessel and year was 235,748,512 tonne-miles over 17,850 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 29.8% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.
From 2022 to 2023, emissions rose 195.7% while distance sailed rose 225.2%and CO₂ per nautical mile fell 9.1%.That points mainly to how much the vessel sailed, rather than the other.
