ASTURIAS against its type
Built in 2010, it is 8 years newer than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 39,362 gross tonnage it is larger than 90% of the other 269 ro-ro ships with a recorded tonnage. It is one of 16 ro-ro ships here under the Portugal flag, 5.1% of the 311 on the register. Its MRV returns name it VIKING AMBER for 2018–2023 and ASTURIAS for 2024–2025. The reported port of registry changed: Singapore (2018–2021), then Majuro (2022–2023), then MADEIRA (2024–2025).
Its 16,631 t of CO₂ for 2025 is 22% below the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 328.4 kg CO₂, close to the type median of 327.0 kg. It logged 4,114 hours at sea against a median of 4,872 hours for its type that year. 6.5% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 7 years with reported emissions, the highest was 2023 (22,145 t) and the lowest 2020 (6,687 t). Its efficiency percentile within the type went from 94 in 2019 to 69 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
