CY INTEROCEAN I against its type
Built in 2016, it is 7 years newer than the median vessel in the other ship types category on this register, which was built in 2009 (451 vessels with a known build year). At 14,766 gross tonnage it is larger than 67% of the other 436 vessels in the other ship types category with a recorded tonnage. It is one of 11 vessels in the other ship types category here under the South Korea flag, 2.2% of the 499 on the register. The reported port of registry changed: Majuro (2018–2020), then Jeju (2021–2025).
Its 9,817 t of CO₂ for 2025 is 1.9 times the median of 5,122 t among the 335 vessels in the other ship types category on this register that reported for 2025. Per nautical mile it emitted 312.8 kg CO₂, 35% above the type median of 231.1 kg. It logged 4,215 hours at sea against a median of 2,231 hours for its type that year. 3.7% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 7 years with reported emissions, the highest was 2019 (15,413 t) and the lowest 2024 (3,103 t). Its efficiency percentile within the type went from 84 in 2018 to 64 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 77 of 119 qualifying other ship typess by EEOI, at the 64th percentile. The dashed line is the type median, 69.3; this vessel reported 86.9.
EEOI divides emissions by transport work, which for this vessel and year was 112,964,672 tonne-miles over 31,388 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 18.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions rose 216.4% and CO₂ per nautical mile fell 25.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
