STI HACKNEY 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 24,162 gross tonnage it is smaller than 88% 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 983 other vessels here, 270 of them oil tankers. The returns for 2018–2025 all give Majuro as port of registry.

Its 10,162 t of CO₂ for 2025 is 28% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 306.0 kg CO₂, 24% below the type median of 403.2 kg. It logged 3,074 hours at sea against a median of 2,030 hours for its type that year. 22.4% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2019 (13,372 t) and the lowest 2021 (9,346 t). Its efficiency percentile within the type went from 82 in 2018 to 91 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,312 of 1,448 qualifying oil tankers by EEOI, at the 91st percentile. The dashed line is the type median, 7.5; this vessel reported 18.9.

EEOI divides emissions by transport work, which for this vessel and year was 537,940,709 tonne-miles over 33,207 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 11.9% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 3.1% while distance sailed fell 7.1%and CO₂ per nautical mile rose 4.3%.That points mainly to how much the vessel sailed, rather than the other.
