MARLIN MAGNETIC against its type
Built in 2019, it is 9 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 29,991 gross tonnage it is smaller than 72% 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. The same builder is recorded for 77 other vessels here, 20 of them oil tankers. Its MRV returns name it MARLIN MAGNETIC for 2019 and STI MAGNETIC for 2020–2025. The reported port of registry changed: Singapore (2019–2022), then Majuro (2023–2025).
Its 6,253 t of CO₂ for 2025 is 21% 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 261.7 kg CO₂, 35% below the type median of 403.2 kg. It logged 1,945 hours at sea against a median of 2,030 hours for its type that year. 8.2% 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 (11,178 t) and the lowest 2022 (2,581 t). Its efficiency percentile within the type went from 8 in 2019 to 74 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,072 of 1,448 qualifying oil tankers by EEOI, at the 74th percentile. The dashed line is the type median, 7.5; this vessel reported 10.3.
EEOI divides emissions by transport work, which for this vessel and year was 604,699,226 tonne-miles over 23,893 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 5.2% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions fell 4.6% while distance sailed fell 8.0%and CO₂ per nautical mile rose 3.7%.That points mainly to how much the vessel sailed, rather than the other.
