IVER BLESSING against its type
Built in 2011, it is 1 year newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 5,948 gross tonnage it is smaller than 98% of the other 2,841 oil tankers with a recorded tonnage. It is one of 10 oil tankers here under the Gibraltar flag, 0.3% of the 3,548 on the register. The same builder is recorded for 983 other vessels here, 270 of them oil tankers. The returns for 2018–2025 all give Gibraltar as port of registry.
Its 5,266 t of CO₂ for 2025 is 34% 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 134.2 kg CO₂, 67% below the type median of 403.2 kg. It logged 4,063 hours at sea against a median of 2,030 hours for its type that year. 4.5% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2023 (7,369 t) and the lowest 2018 (574 t). Of the 7 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 816.9% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.
From 2024 to 2025, emissions rose 1.1% and CO₂ per nautical mile rose 6.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
