STI REGINA against its type

Built in 2014, it is 4 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 29,735 gross tonnage it is smaller than 75% 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 180 other vessels here, 51 of them oil tankers. The returns for 2018–2025 all give Majuro as port of registry.

Its 2,293 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 273.0 kg CO₂, 32% below the type median of 403.2 kg. It logged 659 hours at sea against a median of 2,030 hours for its type that year. 10.2% 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 (6,256 t) and the lowest 2024 (1,792 t). Its efficiency percentile within the type went from 80 in 2018 to 41 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 592 of 1,448 qualifying oil tankers by EEOI, at the 41st percentile. The dashed line is the type median, 7.5; this vessel reported 6.8.

Reported CO₂ in 2025 was 47.2% 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 28.0% and CO₂ per nautical mile fell 3.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
