STI MARVEL 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. The reported port of registry changed: Singapore (2019–2021), then Majuro (2023–2025).
Its 946 t of CO₂ for 2025 is 88% 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 281.5 kg CO₂, 30% below the type median of 403.2 kg. It logged 286 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 6 years with reported emissions, the highest was 2024 (7,311 t) and the lowest 2025 (946 t). Its efficiency percentile within the type went from 4 in 2019 to 75 in 2024 (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.

Reported CO₂ by year
Reported CO₂ in 2025 was 83.0% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions fell 87.1% and CO₂ per nautical mile rose 6.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
