OKIANA against its type

Built in 2004, it is 3 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 38,910 gross tonnage it is larger than 99% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 27 general cargo ships here under the Isle of Man flag, 0.9% of the 3,081 on the register. The same builder is recorded for 468 other vessels here, 92 of them general cargo ships. The returns for 2018–2025 all give Douglas as port of registry.

Its 2,521 t of CO₂ for 2025 is 11% 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 254.1 kg CO₂, 2.1 times the type median of 122.2 kg. It logged 842 hours at sea against a median of 3,044 hours for its type that year. 5.6% 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 2020 (9,336 t) and the lowest 2023 (1,590 t). Of the 6 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 56.7% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 39.8% and CO₂ per nautical mile rose 0.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
