FOS ATHENS against its type
It is one of 27 oil tankers here under the Türkiye flag, 0.8% of the 3,548 on the register. Its MRV returns name it FOS ATHENS for 2019–2022 and T.KURUCESME for 2023–2025. The reported port of registry changed: Majuro (2019–2022), then Istanbul (2023–2025).
Its 3,323 t of CO₂ for 2025 is 58% 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 422.2 kg CO₂, close to the type median of 403.2 kg. It logged 846 hours at sea against a median of 2,030 hours for its type that year. 11.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2023 (7,253 t) and the lowest 2020 (1,262 t). Its efficiency percentile within the type went from 25 in 2019 to 50 in 2024 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 17.5% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions fell 43.5% and CO₂ per nautical mile fell 7.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

This page draws on 6 MRV reporting years, 1 of 5 vessel particulars and a name history. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, a licensed photograph, a sanctions listing and US port state inspections.
Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
