BLUE STAR DELOS against its type

Built in 2011, it is 11 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. The returns for 2018–2025 all give Piraeus as port of registry.

Its 76,713 t of CO₂ for 2025 is 2.6 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 729.8 kg CO₂, 1.6 times the type median of 467.6 kg. It logged 4,680 hours at sea against a median of 4,243 hours for its type that year. 5.9% 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 2019 (83,355 t) and the lowest 2020 (60,088 t). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 0.2% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 5.8% and CO₂ per nautical mile fell 0.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

This page draws on 8 MRV reporting years, 5 of 5 vessel particulars and a licensed photograph. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, a name history, 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.
