SIRIUS against its type

Built in 2009, it is 1 year older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 81,339 gross tonnage it is larger than 73% 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 761 other vessels here, 193 of them oil tankers. The returns for 2018–2021 all give Monrovia as port of registry.

Its 7,217 t of CO₂ for 2021 is close to the median of 7,717 t among the 1,777 oil tankers on this register that reported for 2021. Per nautical mile it emitted 524.3 kg CO₂, 28% above the type median of 409.1 kg. It logged 1,115 hours at sea against a median of 1,921 hours for its type that year. 12.3% of its 2021 emissions were at berth; the median for oil tankers was 8.8%. Across 4 years with reported emissions, the highest was 2019 (26,919 t) and the lowest 2021 (7,217 t). Its efficiency percentile within the type went from 71 in 2018 to 14 in 2021 (lower is more efficient).

Efficiency against its own type2021

Position 236 of 1,636 qualifying oil tankers by EEOI, at the 14th percentile. The dashed line is the type median, 8.4; this vessel reported 5.1.

EEOI divides emissions by transport work, which for this vessel and year was 1,420,627,953 tonne-miles over 13,765 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2021 was 29.2% lower than in 2018, for EU/EEA voyages only.

From 2020 to 2021, emissions fell 21.8% while distance sailed fell 26.4%and CO₂ per nautical mile rose 6.2%.That points mainly to how much the vessel sailed, rather than the other.
