SEAGALAXY against its type
Built in 2019, it is 9 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 63,513 gross tonnage it is larger than 65% of the other 2,841 oil tankers with a recorded tonnage. 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 2021–2025 all give Hong Kong as port of registry.
Its 16,914 t of CO₂ for 2025 is 2.1 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 386.8 kg CO₂, close to the type median of 403.2 kg. It logged 3,938 hours at sea against a median of 2,030 hours for its type that year. 7.5% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2025 (16,914 t) and the lowest 2020 (3,489 t). Its efficiency percentile within the type went from 27 in 2019 to 34 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 495 of 1,448 qualifying oil tankers by EEOI, at the 34th percentile. The dashed line is the type median, 7.5; this vessel reported 6.3.
EEOI divides emissions by transport work, which for this vessel and year was 2,680,454,834 tonne-miles over 43,726 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 119.3% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 130.7% while distance sailed rose 25.4%and CO₂ per nautical mile rose 83.9%.That points mainly to how efficiently it sailed, rather than the other.
