HELLAS MARIANNA against its type
Built in 2018, it is 8 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 29,450 gross tonnage it is smaller than 78% 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 77 other vessels here, 20 of them oil tankers. The returns for 2018–2024 all give Valletta as port of registry.
Its 3,273 t of CO₂ for 2024 is 60% 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 227.4 kg CO₂, 44% below the type median of 408.2 kg. It logged 1,135 hours at sea against a median of 2,020 hours for its type that year. 7.9% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 6 years with reported emissions, the highest was 2018 (8,330 t) and the lowest 2019 (794 t). Its efficiency percentile within the type went from 45 in 2018 to 46 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 723 of 1,566 qualifying oil tankers by EEOI, at the 46th percentile. The dashed line is the type median, 7.6; this vessel reported 7.3.
EEOI divides emissions by transport work, which for this vessel and year was 450,213,205 tonne-miles over 14,395 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 60.7% 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 42.8% while distance sailed fell 33.9%and CO₂ per nautical mile fell 13.5%.That points mainly to how much the vessel sailed, rather than the other.
