DAIANA against its type
Built in 2011, it is 4 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 5,629 gross tonnage it is smaller than 56% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 18 general cargo ships here under the Italy flag, 0.6% of the 3,081 on the register. The same builder is recorded for 127 other vessels here, 52 of them general cargo ships. Its MRV returns name it XIAOYI C for 2018 and DAIANA for 2019–2025. The reported port of registry changed: Cowes (2018), then NAPOLI (2019–2025).
Its 4,065 t of CO₂ for 2025 is 44% above the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 146.3 kg CO₂, 20% above the type median of 122.2 kg. It logged 2,894 hours at sea against a median of 3,044 hours for its type that year. 17.4% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2021 (5,718 t) and the lowest 2019 (2,454 t). Its efficiency percentile within the type was 68 in both 2019 and 2025. Of the 7 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.
