SAMSARA 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 82,870 gross tonnage it is larger than 80% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 194 other vessels here, 56 of them oil tankers. The reported port of registry changed: Valletta (2021–2022), then Monrovia (2023–2025).
Its 9,603 t of CO₂ for 2025 is 21% 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 478.2 kg CO₂, 19% above the type median of 403.2 kg. It logged 2,174 hours at sea against a median of 2,030 hours for its type that year. 10.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2021 (11,472 t) and the lowest 2024 (8,473 t). Its efficiency percentile within the type went from 27 in 2021 to 17 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 242 of 1,448 qualifying oil tankers by EEOI, at the 17th percentile. The dashed line is the type median, 7.5; this vessel reported 4.9.
EEOI divides emissions by transport work, which for this vessel and year was 1,951,886,179 tonne-miles over 20,082 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 16.3% lower than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 13.3% while distance sailed rose 30.6%and CO₂ per nautical mile fell 13.2%.That points mainly to how much the vessel sailed, rather than the other.
