RELIABLE WARRIOR against its type
Built in 2017, it is 7 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 81,287 gross tonnage it is larger than 72% of the other 2,841 oil tankers with a recorded tonnage. It is one of 180 oil tankers here under the Bahamas flag, 5.1% of the 3,548 on the register. The same builder is recorded for 761 other vessels here, 193 of them oil tankers. The returns for 2018–2025 all give Andros as port of registry.
Its 5,056 t of CO₂ for 2025 is 36% 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 538.0 kg CO₂, 33% above the type median of 403.2 kg. It logged 876 hours at sea against a median of 2,030 hours for its type that year. 10.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2020 (14,271 t) and the lowest 2023 (3,553 t). Its efficiency percentile within the type went from 25 in 2018 to 92 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 1,330 of 1,448 qualifying oil tankers by EEOI, at the 92nd percentile. The dashed line is the type median, 7.5; this vessel reported 20.1.
EEOI divides emissions by transport work, which for this vessel and year was 252,159,601 tonne-miles over 9,397 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 30.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions rose 5.4% while distance sailed fell 24.0%and CO₂ per nautical mile rose 38.6%.That points mainly to how efficiently it sailed, rather than the other.
