BRITISH HERITAGE against its type

Built in 2017, it is 7 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 85,445 gross tonnage it is larger than 85% of the other 2,841 oil tankers with a recorded tonnage. It is one of 72 oil tankers here under the Denmark flag, 2.0% of the 3,548 on the register. Its MRV returns name it BRITISH HERITAGE for 2018–2019 and ELISABETH MAERSK for 2020–2025. The reported port of registry changed: Douglas (2018–2019), then Svendborg (2020–2025).

Its 8,137 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 453.0 kg CO₂, 12% above the type median of 403.2 kg. It logged 1,453 hours at sea against a median of 2,030 hours for its type that year. 4.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2023 (18,866 t) and the lowest 2020 (4,257 t). Its efficiency percentile within the type went from 24 in 2018 to 3 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 40 of 1,448 qualifying oil tankers by EEOI, at the 3rd percentile. The dashed line is the type median, 7.5; this vessel reported 3.3.

Reported CO₂ in 2025 was 49.8% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 30.5% while distance sailed fell 37.1%and CO₂ per nautical mile rose 10.5%.That points mainly to how much the vessel sailed, rather than the other.
