STI QUEENS against its type

Built in 2015, it is 5 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 7,695 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 269.8 kg CO₂, 33% below the type median of 403.2 kg. It logged 2,425 hours at sea against a median of 2,030 hours for its type that year. 5.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2018 (8,018 t) and the lowest 2020 (1,738 t). Its efficiency percentile within the type went from 74 in 2018 to 79 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,144 of 1,448 qualifying oil tankers by EEOI, at the 79th percentile. The dashed line is the type median, 7.5; this vessel reported 11.3.

EEOI divides emissions by transport work, which for this vessel and year was 683,430,728 tonne-miles over 28,524 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 4.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2021, so the series has gaps.

From 2024 to 2025, emissions rose 202.5% while distance sailed rose 228.9%and CO₂ per nautical mile fell 8.0%.That points mainly to how much the vessel sailed, rather than the other.
