OCEAN EUPHROSYNE against its type
Built in 2006, it is 4 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 29,242 gross tonnage it is smaller than 79% 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 983 other vessels here, 270 of them oil tankers. Its MRV returns name it TORM REPUBLICAN for 2018–2023 and OCEAN EUPHROSYNE for 2025. The reported port of registry changed: Copenhagen (2018–2023), then Monrovia (2025).
Its 2,883 t of CO₂ for 2025 is 64% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 266.1 kg CO₂, 34% below the type median of 403.2 kg. It logged 1,405 hours at sea against a median of 2,030 hours for its type that year. 6.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2022 (5,599 t) and the lowest 2025 (2,883 t). Its efficiency percentile within the type went from 55 in 2021 to 68 in 2023 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2025 was 28.6% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2020, 2024, so the series has gaps.
From 2023 to 2025, emissions fell 47.8% and CO₂ per nautical mile rose 5.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
