OPALINE 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 33,960 gross tonnage it is larger than 87% 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 59 other vessels here, 45 of them ro-ro ships. The returns for 2019–2025 all give Valletta as port of registry.
Its 17,695 t of CO₂ for 2025 is 17% 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 323.9 kg CO₂, close to the type median of 327.0 kg. It logged 4,012 hours at sea against a median of 4,872 hours for its type that year. 6.7% 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 2021 (26,236 t) and the lowest 2025 (17,695 t). Its efficiency percentile within the type was 29 in both 2019 and 2025. Of the 8 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 57 of 192 qualifying ro-ro ships by EEOI, at the 29th percentile. The dashed line is the type median, 85.3; this vessel reported 66.5.
EEOI divides emissions by transport work, which for this vessel and year was 266,253,085 tonne-miles over 54,637 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 30.3% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 17.4% while distance sailed fell 16.5%and CO₂ per nautical mile fell 1.1%.That points mainly to how much the vessel sailed, rather than the other.
