SINGLE against its type
Built in 2007, it is 3 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 23,248 gross tonnage it is smaller than 90% 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 983 other vessels here, 270 of them oil tankers. Its MRV returns name it SINGLE for 2018–2022 and STARLIGHT I for 2023–2025. The returns for 2018–2025 all give Majuro, Marshall Islands as port of registry.
Its 5,514 t of CO₂ for 2025 is 30% 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 332.2 kg CO₂, 18% below the type median of 403.2 kg. It logged 1,681 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 7 years with reported emissions, the highest was 2021 (15,550 t) and the lowest 2020 (992 t). Its efficiency percentile within the type went from 90 in 2018 to 93 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,341 of 1,448 qualifying oil tankers by EEOI, at the 93rd percentile. The dashed line is the type median, 7.5; this vessel reported 20.6.
EEOI divides emissions by transport work, which for this vessel and year was 268,206,226 tonne-miles over 16,599 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 43.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.
From 2024 to 2025, emissions rose 163.5% and CO₂ per nautical mile fell 2.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
