SEA DISCOVERY against its type

Built in 2012, it is 5 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 6,872 gross tonnage it is larger than 54% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 187 general cargo ships here under the Portugal flag, 6.1% of the 3,081 on the register. The reported port of registry changed: Limassol (2019–2022), then Oslo (2023–2024), then Madeira (2025).

Its 8,198 t of CO₂ for 2025 is 2.9 times the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 153.9 kg CO₂, 26% above the type median of 122.2 kg. It logged 5,212 hours at sea against a median of 3,044 hours for its type that year. 4.1% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2018 (9,770 t) and the lowest 2024 (7,255 t). Of the 7 comparable vessels listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 16.1% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 13.0% and CO₂ per nautical mile rose 1.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
