BIT HERO against its type

Built in 2018, it is 8 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 7,447 gross tonnage it is smaller than 97% of the other 2,841 oil tankers with a recorded tonnage. It is one of 5 oil tankers here under the Netherlands flag, 0.1% of the 3,548 on the register. The returns for 2018–2025 all give Dordrecht as port of registry.

Its 1,950 t of CO₂ for 2025 is 75% 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 1,536 hours at sea against a median of 2,030 hours for its type that year. 1.1% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2018 (5,570 t) and the lowest 2025 (1,950 t). Of the 6 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 65.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2023, 2024, so the series has gaps.

From 2022 to 2025, emissions fell 16.8% and CO₂ per nautical mile fell 16.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 5 MRV reporting years, 4 of 5 vessel particulars and a licensed photograph. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, a name history, 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.
