SEA RUBY against its type
Built in 2017, it is 7 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 154,236 gross tonnage it is larger than 87% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% 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 2022–2023 all give Majuro as port of registry.
Its 28,775 t of CO₂ for 2023 is 3.8 times the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 528.1 kg CO₂, 29% above the type median of 408.5 kg. It logged 5,479 hours at sea against a median of 1,807 hours for its type that year. 10.3% 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 (28,775 t) and the lowest 2022 (5,193 t). Its efficiency percentile within the type went from 1 in 2018 to 6 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 102 of 1,615 qualifying oil tankers by EEOI, at the 6th percentile. The dashed line is the type median, 8.0; this vessel reported 4.3.
EEOI divides emissions by transport work, which for this vessel and year was 6,738,840,749 tonne-miles over 54,485 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 159.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, so the series has gaps.
From 2022 to 2023, emissions rose 454.1% while distance sailed rose 421.9%and CO₂ per nautical mile rose 6.2%.That points mainly to how much the vessel sailed, rather than the other.
