BLUE STAR PATMOS against its type
Built in 2012, it is 12 years newer than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 18,498 gross tonnage it is smaller than 58% of the other 470 ro-pax ships with a recorded tonnage. It is one of 48 ro-pax ships here under the Greece flag, 9.7% of the 493 on the register. The same builder is recorded for 660 other vessels here, 7 of them ro-pax ships. Blue Star Ferries is linked to 2 vessels on this register. The returns for 2018–2025 all give Piraeus as port of registry.
Its 88,731 t of CO₂ for 2025 is 3.0 times the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 733.6 kg CO₂, 1.6 times the type median of 467.6 kg. It logged 5,884 hours at sea against a median of 4,243 hours for its type that year. 0.4% of its 2025 emissions were at berth; the median for ro-pax ships was 6.7%. Across 8 years with reported emissions, the highest was 2025 (88,731 t) and the lowest 2020 (50,670 t). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.
