ARCHELAOS 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 62,508 gross tonnage it is larger than 59% of the other 2,841 oil tankers with a recorded tonnage. It is one of 215 oil tankers here under the Greece flag, 6.1% of the 3,548 on the register. The same builder is recorded for 194 other vessels here, 56 of them oil tankers. Its MRV returns name it FOLEGANDROS for 2019–2020, ARCHELAOS for 2021, HIBERNIAN TIDE for 2022 and MINERVA ZOE for 2023–2025. The reported port of registry changed: Piraeus (2019–2020), then Monrovia (2021–2022), then PIRAEUS (2023–2025).
Its 4,034 t of CO₂ for 2025 is 49% 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 457.6 kg CO₂, 13% above the type median of 403.2 kg. It logged 753 hours at sea against a median of 2,030 hours for its type that year. 11.4% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2020 (20,225 t) and the lowest 2021 (1,149 t). Its efficiency percentile within the type went from 13 in 2019 to 35 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 510 of 1,448 qualifying oil tankers by EEOI, at the 35th percentile. The dashed line is the type median, 7.5; this vessel reported 6.4.
EEOI divides emissions by transport work, which for this vessel and year was 632,335,423 tonne-miles over 8,816 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 55.3% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 65.8% while distance sailed fell 71.7%and CO₂ per nautical mile rose 21.1%.That points mainly to how much the vessel sailed, rather than the other.
