CORVO against its type
Built in 2007, it is 2 years older than the median vessel in the other ship types category on this register, which was built in 2009 (451 vessels with a known build year). At 7,064 gross tonnage it is smaller than 72% of the other 436 vessels in the other ship types category with a recorded tonnage. It is one of 52 vessels in the other ship types category here under the Portugal flag, 10.4% of the 499 on the register. The same builder is recorded for 22 other vessels here, one of them a vessel in the other ship types category. The returns for 2018–2025 all give Ponta Delgada as port of registry.
Its 11,310 t of CO₂ for 2025 is 2.2 times the median of 5,122 t among the 335 vessels in the other ship types category on this register that reported for 2025. Per nautical mile it emitted 210.7 kg CO₂, close to the type median of 231.1 kg. It logged 3,931 hours at sea against a median of 2,231 hours for its type that year. 7.0% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 8 years with reported emissions, the highest was 2019 (13,224 t) and the lowest 2020 (5,632 t). Of the 6 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 48 of 119 qualifying other ship typess by EEOI, at the 40th percentile. The dashed line is the type median, 69.3; this vessel reported 55.0.
EEOI divides emissions by transport work, which for this vessel and year was 205,485,283 tonne-miles over 53,685 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 19.0% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 12.8% and CO₂ per nautical mile rose 0.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
