FRIO 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 81,346 gross tonnage it is larger than 74% 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 761 other vessels here, 193 of them oil tankers. Its MRV returns name it FRIO for 2018–2021 and SEAWAYS FRIO for 2022–2025. The returns for 2018–2025 all give Majuro as port of registry.
Its 19,266 t of CO₂ for 2025 is 2.4 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 484.3 kg CO₂, 20% above the type median of 403.2 kg. It logged 3,948 hours at sea against a median of 2,030 hours for its type that year. 6.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2025 (19,266 t) and the lowest 2022 (5,209 t). Its efficiency percentile within the type went from 8 in 2018 to 31 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 451 of 1,448 qualifying oil tankers by EEOI, at the 31st percentile. The dashed line is the type median, 7.5; this vessel reported 6.0.
EEOI divides emissions by transport work, which for this vessel and year was 3,189,682,119 tonne-miles over 39,780 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 0.3% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 246.3% while distance sailed rose 219.4%and CO₂ per nautical mile rose 8.4%.That points mainly to how much the vessel sailed, rather than the other.
