SANDRA 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 164,688 gross tonnage it is larger than 99% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. Its MRV returns name it SANDRA for 2018–2019 and WEST LOYALTY for 2023–2025. The reported port of registry changed: Marseille (2018–2019), then Majuro (2023–2025).
Its 11,204 t of CO₂ for 2025 is 41% 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 814.7 kg CO₂, 2.0 times the type median of 403.2 kg. It logged 1,337 hours at sea against a median of 2,030 hours for its type that year. 8.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2019 (36,636 t) and the lowest 2023 (4,998 t). Its efficiency percentile within the type went from 4 in 2018 to 3 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 49 of 1,448 qualifying oil tankers by EEOI, at the 3rd percentile. The dashed line is the type median, 7.5; this vessel reported 3.5.
EEOI divides emissions by transport work, which for this vessel and year was 3,219,683,908 tonne-miles over 13,753 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 44.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2024, so the series has gaps.
From 2023 to 2025, emissions rose 124.2% while distance sailed rose 147.0%and CO₂ per nautical mile fell 9.2%.That points mainly to how much the vessel sailed, rather than the other.
