GAIA BLU against its type
Built in 1981, it is 30 years older than the median offshore vessel on this register, which was built in 2011 (410 vessels with a known build year). At 2,024 gross tonnage it is smaller than 74% 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 2 other vessels here, one of them an offshore vessel.
Its 4,631 t of CO₂ for 2025 is 14% above the median of 4,049 t among the 390 offshore vessels on this register that reported for 2025. Per nautical mile it emitted 194.2 kg CO₂, 44% below the type median of 348.3 kg. It logged 4,465 hours at sea against a median of 3,550 hours for its type that year. 11.8% of its 2025 emissions were at berth; the median for offshore vessels was 6.4%. The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.
