UOG IOANNIS V 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 42,010 gross tonnage it is smaller than 63% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The returns for 2023–2025 all give MAJURO as port of registry.
Its 637 t of CO₂ for 2025 is 92% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 343.4 kg CO₂, 15% below the type median of 403.2 kg. It logged 165 hours at sea against a median of 2,030 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 3 years with reported emissions, the highest was 2024 (12,243 t) and the lowest 2025 (637 t). Of the 3 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
