SOFIA II against its type
Built in 2008, it is 2 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 55,898 gross tonnage it is smaller than 57% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 57 other vessels here, 42 of them oil tankers. Its MRV returns name it STAVANGER BLISS for 2018 and SOFIA II for 2023–2024. The returns for 2023–2024 all give Monrovia as port of registry.
Its 8,713 t of CO₂ for 2024 is close to the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 634.7 kg CO₂, 1.6 times the type median of 408.2 kg. It logged 2,300 hours at sea against a median of 2,020 hours for its type that year. 28.7% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Its efficiency percentile within the type went from 44 in 2023 to 67 in 2024 (lower is more efficient). The one sister ship listed below with a 2024 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2024
Position 1,044 of 1,566 qualifying oil tankers by EEOI, at the 67th percentile. The dashed line is the type median, 7.6; this vessel reported 9.1.
EEOI divides emissions by transport work, which for this vessel and year was 956,428,101 tonne-miles over 13,728 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 44.4% lower than in 2023, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, so the series has gaps.
From 2023 to 2024, emissions fell 44.4% while distance sailed fell 72.5%and CO₂ per nautical mile rose 102.3%.
