SEAODYSSEY against its type
It is one of 139 oil tankers here under the Hong Kong flag, 3.9% of the 3,548 on the register. The returns for 2020–2025 all give Hong Kong as port of registry.
Its 15,809 t of CO₂ for 2025 is 2.0 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 397.0 kg CO₂, close to the type median of 403.2 kg. It logged 3,619 hours at sea against a median of 2,030 hours for its type that year. 5.3% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2025 (15,809 t) and the lowest 2022 (1,752 t). Its efficiency percentile within the type went from 35 in 2020 to 33 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 482 of 1,448 qualifying oil tankers by EEOI, at the 33rd percentile. The dashed line is the type median, 7.5; this vessel reported 6.2.
EEOI divides emissions by transport work, which for this vessel and year was 2,533,530,449 tonne-miles over 39,819 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 504.8% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 373.6% while distance sailed rose 373.5%and CO₂ per nautical mile rose <0.1%.That points mainly to how much the vessel sailed, rather than the other.
