OLYMPOS SEAWAYS against its type
Built in 2002, it is the same age as the median ro-ro ship on this register (build year 2002, 281 vessels with a known build year). At 26,469 gross tonnage it is larger than 68% of the other 269 ro-ro ships with a recorded tonnage. It is one of 18 ro-ro ships here under the Türkiye flag, 5.8% of the 311 on the register. The same builder is recorded for 59 other vessels here, 45 of them ro-ro ships. Its MRV returns name it UND BIRLIK for 2018–2019 and OLYMPOS SEAWAYS for 2020–2025. The returns for 2018–2025 all give Istanbul as port of registry.
Its 49,110 t of CO₂ for 2025 is 2.3 times the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 369.6 kg CO₂, 13% above the type median of 327.0 kg. It logged 7,105 hours at sea against a median of 4,872 hours for its type that year. 1.1% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 8 years with reported emissions, the highest was 2025 (49,110 t) and the lowest 2020 (35,242 t). Its efficiency percentile within the type went from 48 in 2018 to 84 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 162 of 192 qualifying ro-ro ships by EEOI, at the 84th percentile. The dashed line is the type median, 85.3; this vessel reported 163.9.
EEOI divides emissions by transport work, which for this vessel and year was 299,544,617 tonne-miles over 132,892 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 7.8% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 22.7% while distance sailed rose 19.3%and CO₂ per nautical mile rose 2.8%.That points mainly to how much the vessel sailed, rather than the other.
