STI BERYL 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). It is one of 28 oil tankers here under the India flag, 0.8% 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 STI BERYL for 2018–2021 and JAG PRIYANKA for 2024–2025. The reported port of registry changed: Majuro (2018–2021), then Mumbai (2024–2025).
Its 2,260 t of CO₂ for 2025 is 71% 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 295.3 kg CO₂, 27% below the type median of 403.2 kg. It logged 708 hours at sea against a median of 2,030 hours for its type that year. 11.3% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2021 (8,416 t) and the lowest 2025 (2,260 t). Its efficiency percentile within the type went from 82 in 2019 to 63 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 914 of 1,448 qualifying oil tankers by EEOI, at the 63rd percentile. The dashed line is the type median, 7.5; this vessel reported 8.6.
EEOI divides emissions by transport work, which for this vessel and year was 263,098,952 tonne-miles over 7,653 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 26.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 41.9% while distance sailed fell 48.2%and CO₂ per nautical mile rose 12.1%.That points mainly to how much the vessel sailed, rather than the other.
