SIRENA against its type

Built in 1999, it is 11 years older than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 30,277 gross tonnage it is smaller than 81% of the other 177 cruise ships with a recorded tonnage. It is one of 13 cruise ships here under the Marshall Islands flag, 6.4% of the 202 on the register. The same builder is recorded for 51 other vessels here, 35 of them cruise ships. Oceania Cruises is linked to 6 vessels on this register. The returns for 2018–2025 all give Majuro as port of registry.

Its 22,530 t of CO₂ for 2025 is 28% below the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 515.7 kg CO₂, 37% below the type median of 821.3 kg. It logged 3,066 hours at sea against a median of 3,133 hours for its type that year. 16.0% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 7 years with reported emissions, the highest was 2023 (23,968 t) and the lowest 2020 (920 t). Of the 8 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 89.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.

From 2024 to 2025, emissions rose 15.1% and CO₂ per nautical mile rose 1.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 7 MRV reporting years, 5 of 5 vessel particulars, AIS movements in Norwegian waters, a licensed photograph and US port state inspections. Not found in the sources for this vessel: an efficiency ranking, a name history and a sanctions listing.

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.
