PALLADIUM 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 62,350 gross tonnage it is larger than 58% 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 461 other vessels here, 179 of them oil tankers. Its MRV returns name it SIGNAL MAYA for 2018–2021 and PALLADIUM for 2024–2025. The reported port of registry changed: VALLETTA (2018–2021), then Monrovia (2024–2025).
Its 6,833 t of CO₂ for 2025 is 14% 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 474.7 kg CO₂, 18% above the type median of 403.2 kg. It logged 1,199 hours at sea against a median of 2,030 hours for its type that year. 7.3% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2020 (19,520 t) and the lowest 2025 (6,833 t). Its efficiency percentile within the type went from 62 in 2018 to 29 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 426 of 1,448 qualifying oil tankers by EEOI, at the 29th percentile. The dashed line is the type median, 7.5; this vessel reported 5.9.
EEOI divides emissions by transport work, which for this vessel and year was 1,154,184,122 tonne-miles over 14,394 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 22.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 23.3% while distance sailed fell 25.2%and CO₂ per nautical mile rose 2.5%.That points mainly to how much the vessel sailed, rather than the other.
