OSMAN PRINCE against its type
Built in 1984, it is 23 years older than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 10,733 gross tonnage it is larger than 67% of the other 2,665 general cargo ships with a recorded tonnage. 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 OSMAN PRINCE for 2018–2019 and PROFESSOR B for 2021–2022. The returns for 2018–2022 all give Moroni as port of registry.
Its 494 t of CO₂ for 2022 is 87% below the median of 3,889 t among the 1,306 general cargo ships on this register that reported for 2022. Per nautical mile it emitted 296.3 kg CO₂, 1.5 times the type median of 193.6 kg. It logged 208 hours at sea against a median of 1,979 hours for its type that year. 8.5% of its 2022 emissions were at berth; the median for general cargo ships was 4.3%. Across 4 years with reported emissions, the highest was 2021 (721 t) and the lowest 2018 (205 t).

Reported CO₂ by year
Reported CO₂ in 2022 was 141.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2021 to 2022, emissions fell 31.5% and CO₂ per nautical mile rose 34.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
