ASSO VENTIQUATTRO against its type
Built in 2001, it is 10 years older than the median offshore vessel on this register, which was built in 2011 (410 vessels with a known build year). At 2,469 gross tonnage it is smaller than 68% of the other 396 offshore vessels with a recorded tonnage. It is one of 19 offshore vessels here under the Italy flag, 4.6% of the 413 on the register. The same builder is recorded for 12 other vessels here.
Its 7,128 t of CO₂ for 2025 is 1.8 times the median of 4,049 t among the 390 offshore vessels on this register that reported for 2025. Per nautical mile it emitted 537.6 kg CO₂, 1.5 times the type median of 348.3 kg. It logged 7,391 hours at sea against a median of 3,550 hours for its type that year. 4.2% of its 2025 emissions were at berth; the median for offshore vessels was 6.4%. Of the 8 comparable vessels listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.
