PORTARIA against its type
Built in 2010, it is the same age as the median chemical tanker on this register (build year 2010, 1,951 vessels with a known build year). At 23,342 gross tonnage it is larger than 53% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. The reported port of registry changed: Geranium Shiptrade SA (2022), then VALLETTA (2023–2025).
Its 11,296 t of CO₂ for 2025 is 2.0 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 295.7 kg CO₂, 18% above the type median of 250.2 kg. It logged 4,854 hours at sea against a median of 2,106 hours for its type that year. 16.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2023 (12,730 t) and the lowest 2024 (11,110 t). Its efficiency percentile within the type went from 64 in 2022 to 60 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.
