ACQUAMARINA against its type

Built in 2004, it is 6 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 8,428 gross tonnage it is smaller than 87% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 43 chemical tankers here under the Italy flag, 1.8% of the 2,344 on the register. Its MRV returns name it ACQUAMARINA for 2018–2023 and GENNARO IEVOLI for 2024–2025. The returns for 2019–2025 all give Ancona as port of registry.

Its 10,539 t of CO₂ for 2025 is 1.9 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 248.6 kg CO₂, close to the type median of 250.2 kg. It logged 4,441 hours at sea against a median of 2,106 hours for its type that year. 7.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2023 (14,944 t) and the lowest 2025 (10,539 t). Its efficiency percentile within the type went from 91 in 2018 to 99 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.
