NEPTUNE DYNAMIS against its type
Built in 2002, it is the same age as the median ro-ro ship on this register (build year 2002, 281 vessels with a known build year). At 21,554 gross tonnage it is larger than 52% of the other 269 ro-ro ships with a recorded tonnage. It is one of 52 ro-ro ships here under the Malta flag, 16.7% of the 311 on the register. The same builder is recorded for 33 other vessels here, 8 of them ro-ro ships. The returns for 2018–2025 all give Valletta as port of registry.
Its 19,250 t of CO₂ for 2025 is close to the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 310.5 kg CO₂, close to the type median of 327.0 kg. It logged 5,249 hours at sea against a median of 4,872 hours for its type that year. 7.4% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 8 years with reported emissions, the highest was 2020 (20,853 t) and the lowest 2021 (17,254 t). Its efficiency percentile within the type went from 93 in 2018 to 97 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.
