NAVE RIGEL against its type
Built in 2013, it is 3 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 42,341 gross tonnage it is smaller than 62% 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 196 other vessels here, 75 of them oil tankers. The returns for 2019–2025 all give Majuro as port of registry.
Its 192 t of CO₂ for 2025 is 98% 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 435.2 kg CO₂, close to the type median of 403.2 kg. It logged 60 hours at sea against a median of 2,030 hours for its type that year. 0.0% 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 (8,361 t) and the lowest 2025 (192 t). Its efficiency percentile within the type went from 22 in 2019 to 76 in 2024 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 1,200 of 1,566 qualifying oil tankers by EEOI, at the 76th percentile. The dashed line is the type median, 7.6; this vessel reported 10.7.
EEOI divides emissions by transport work, which for this vessel and year was 563,826,454 tonne-miles over 15,111 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 97.7% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 96.8% and CO₂ per nautical mile rose 9.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
