PIS SUMATERA 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 29,715 gross tonnage it is smaller than 76% of the other 2,841 oil tankers with a recorded tonnage. It is one of 237 oil tankers here under the Singapore flag, 6.7% 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 VILLE for 2018–2022 and PIS SUMATERA for 2025. The reported port of registry changed: Majuro (2018–2022), then SINGAPORE (2025).

Its 5,752 t of CO₂ for 2025 is 27% 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 309.0 kg CO₂, 23% below the type median of 403.2 kg. It logged 1,695 hours at sea against a median of 2,030 hours for its type that year. 6.3% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2022 (8,094 t) and the lowest 2018 (2,060 t). Its efficiency percentile within the type went from 50 in 2020 to 67 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 964 of 1,448 qualifying oil tankers by EEOI, at the 67th percentile. The dashed line is the type median, 7.5; this vessel reported 9.1.

EEOI divides emissions by transport work, which for this vessel and year was 632,775,578 tonne-miles over 18,612 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 179.2% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2021, 2023, 2024, so the series has gaps.

From 2022 to 2025, emissions fell 28.9% while distance sailed fell 28.9%and CO₂ per nautical mile fell 0.1%.That points mainly to how much the vessel sailed, rather than the other.
