KUBROSLI Y against its type
Built in 1981, it is 26 years older than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). It is one of 34 general cargo ships here under the Comoros flag, 1.1% of the 3,081 on the register. Its MRV returns name it PATRA 3 for 2018–2020 and KUBROSLI Y for 2021–2025. The reported port of registry changed: Varna (2018–2020), then Moroni (2021–2025).
Its 741 t of CO₂ for 2025 is 74% below 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 126.2 kg CO₂, close to the type median of 122.2 kg. It logged 614 hours at sea against a median of 3,044 hours for its type that year. 6.8% 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 2019 (5,726 t) and the lowest 2022 (557 t). Its efficiency percentile within the type went from 43 in 2020 to 72 in 2023 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 85.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 39.5% and CO₂ per nautical mile rose 1.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
