BW ORINOCO against its type
Built in 2007, it is 3 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 43,797 gross tonnage it is smaller than 59% of the other 2,841 oil tankers with a recorded tonnage. It is one of 8 oil tankers here under the Antigua and Barbuda flag, 0.2% 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 BW ORINOCO for 2018–2020 and MARALTA for 2024. The reported port of registry changed: Singapore (2018–2020), then St. John's (2024).
Its 4,028 t of CO₂ for 2024 is 51% below the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 361.8 kg CO₂, 11% below the type median of 408.2 kg. It logged 989 hours at sea against a median of 2,020 hours for its type that year. 4.1% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 4 years with reported emissions, the highest was 2018 (9,045 t) and the lowest 2019 (2,553 t). Its efficiency percentile within the type went from 66 in 2018 to 26 in 2024 (lower is more efficient). The one sister ship listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2024
Position 408 of 1,566 qualifying oil tankers by EEOI, at the 26th percentile. The dashed line is the type median, 7.6; this vessel reported 5.7.
EEOI divides emissions by transport work, which for this vessel and year was 709,202,465 tonne-miles over 11,133 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 55.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, so the series has gaps.
From 2020 to 2024, emissions fell 54.5% while distance sailed fell 43.6%and CO₂ per nautical mile fell 19.3%.That points mainly to how much the vessel sailed, rather than the other.
