PRINSESSE ISABELLA against its type

Built in 2015, it is 15 years newer than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 5,478 gross tonnage it is smaller than 94% of the other 470 ro-pax ships with a recorded tonnage. It is one of 29 ro-pax ships here under the Denmark flag, 5.9% of the 493 on the register. The same builder is recorded for 6 other vessels here, 2 of them ro-pax ships. The returns for 2022–2025 all give Sælvig as port of registry.

Its 6,146 t of CO₂ for 2025 is 80% below the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 120.4 kg CO₂, 74% below the type median of 467.6 kg. It logged 4,771 hours at sea against a median of 4,243 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for ro-pax ships was 6.7%. Across 4 years with reported emissions, the highest was 2022 (7,086 t) and the lowest 2023 (5,482 t). Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Sources and how to read this

This page draws on 4 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.
