IVER BEST 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 6,260 t of CO₂ for 2025 is 21% 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 150.7 kg CO₂, 63% below the type median of 403.2 kg. It logged 4,449 hours at sea against a median of 2,030 hours for its type that year. 10.1% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2025 (6,260 t) and the lowest 2021 (1,742 t). Of the 7 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 16.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.

From 2024 to 2025, emissions rose 30.6% and CO₂ per nautical mile rose 5.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

This page draws on 7 MRV reporting years and 5 of 5 vessel particulars. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, a name history, a licensed photograph, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
