DIONE against its type
Built in 2017, it is 5 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 44,043 gross tonnage it is larger than 76% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,601 bulk carriers here under the Panama flag, 19.7% of the 8,138 on the register. The returns for 2018–2025 all give Panama as port of registry.
Its 4,818 t of CO₂ for 2025 is 49% above the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 337.8 kg CO₂, 30% above the type median of 260.7 kg. It logged 1,256 hours at sea against a median of 1,199 hours for its type that year. 5.7% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2021 (11,442 t) and the lowest 2020 (1,856 t). Its efficiency percentile within the type went from 19 in 2018 to 30 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.
