IOANNA against its type
Built in 2008, it is 2 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 160,836 gross tonnage it is larger than 94% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 761 other vessels here, 193 of them oil tankers. The returns for 2024–2025 all give Monrovia as port of registry.
Its 3,208 t of CO₂ for 2024 is 61% below the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 552.9 kg CO₂, 35% above the type median of 408.2 kg. It logged 641 hours at sea against a median of 2,020 hours for its type that year. 9.0% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Of the 3 sister ships listed below with a 2024 return, 3 reported a lower CO₂ per nautical mile than this vessel.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.
