STI STEADFAST against its type

Built in 2016, it is 6 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 63,915 gross tonnage it is larger than 66% 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 196 other vessels here, 75 of them oil tankers. The returns for 2018–2025 all give Majuro as port of registry.

Its 13,750 t of CO₂ for 2025 is 1.7 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 436.2 kg CO₂, close to the type median of 403.2 kg. It logged 2,691 hours at sea against a median of 2,030 hours for its type that year. 3.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2025 (13,750 t) and the lowest 2018 (2,369 t). Its efficiency percentile within the type went from 17 in 2018 to 22 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 315 of 1,448 qualifying oil tankers by EEOI, at the 22nd percentile. The dashed line is the type median, 7.5; this vessel reported 5.4.

Reported CO₂ in 2025 was 480.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2023, so the series has gaps.

From 2024 to 2025, emissions rose 57.0% while distance sailed rose 61.6%and CO₂ per nautical mile fell 2.8%.That points mainly to how much the vessel sailed, rather than the other.
