HYDRA against its type
Built in 2004, it is 6 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 56,172 gross tonnage it is smaller than 56% of the other 2,841 oil tankers with a recorded tonnage. It is one of 289 oil tankers here under the Malta flag, 8.1% of the 3,548 on the register. The same builder is recorded for 57 other vessels here, 42 of them oil tankers. The returns for 2018–2025 all give Valletta as port of registry.
Its 3,673 t of CO₂ for 2024 is 55% 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 380.1 kg CO₂, close to the type median of 408.2 kg. It logged 868 hours at sea against a median of 2,020 hours for its type that year. 6.9% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 5 years with reported emissions, the highest was 2019 (12,995 t) and the lowest 2020 (2,475 t). Its efficiency percentile within the type went from 51 in 2018 to 12 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.
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 184 of 1,566 qualifying oil tankers by EEOI, at the 12th percentile. The dashed line is the type median, 7.6; this vessel reported 4.5.
EEOI divides emissions by transport work, which for this vessel and year was 819,790,179 tonne-miles over 9,662 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 12.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2023 to 2024, emissions rose 35.0% while distance sailed rose 67.1%and CO₂ per nautical mile fell 19.2%.That points mainly to how much the vessel sailed, rather than the other.
