HISTRIA CROWN against its type

Built in 2012, it is 2 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 25,864 gross tonnage it is smaller than 87% of the other 2,841 oil tankers with a recorded tonnage. It is one of 289 oil tankers here under the Malta flag, 8.1% of the 3,548 on the register. The same builder is recorded for 21 other vessels here, 14 of them oil tankers. The reported port of registry changed: Monrovia (2018–2022), then Valletta (2023–2025).

Its 9,413 t of CO₂ for 2025 is 19% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 330.3 kg CO₂, 18% below the type median of 403.2 kg. It logged 3,143 hours at sea against a median of 2,030 hours for its type that year. 16.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2024 (12,317 t) and the lowest 2018 (7,658 t). Its efficiency percentile within the type went from 86 in 2018 to 88 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025

Position 1,279 of 1,448 qualifying oil tankers by EEOI, at the 88th percentile. The dashed line is the type median, 7.5; this vessel reported 16.9.

EEOI divides emissions by transport work, which for this vessel and year was 557,992,294 tonne-miles over 28,501 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 22.9% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 23.6% while distance sailed fell 16.0%and CO₂ per nautical mile fell 9.0%.That points mainly to how much the vessel sailed, rather than the other.
