KINYRAS 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 86,952 gross tonnage it is larger than 86% 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. Its MRV returns name it RIDGEBURY CAPTAIN DROGIN for 2018–2021 and KINYRAS for 2022–2025. The reported port of registry changed: Majuro (2018–2021), then Monrovia (2022–2025).
Its 10,699 t of CO₂ for 2024 is 31% above the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 543.8 kg CO₂, 33% above the type median of 408.2 kg. It logged 1,588 hours at sea against a median of 2,020 hours for its type that year. 0.0% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 6 years with reported emissions, the highest was 2020 (20,968 t) and the lowest 2021 (2,512 t). Its efficiency percentile within the type went from 60 in 2018 to 20 in 2024 (lower is more efficient). Of the 3 sister ships listed below with a 2024 return, 2 reported a lower CO₂ per nautical mile than this vessel.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024
Position 313 of 1,566 qualifying oil tankers by EEOI, at the 20th percentile. The dashed line is the type median, 7.6; this vessel reported 5.1.
EEOI divides emissions by transport work, which for this vessel and year was 2,089,730,469 tonne-miles over 19,677 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 44.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2022 to 2024, emissions fell 11.3% while distance sailed fell 12.7%and CO₂ per nautical mile rose 1.6%.That points mainly to how much the vessel sailed, rather than the other.
