T RIGEL against its type

Built in 2020, it is 10 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 13,872 gross tonnage it is smaller than 93% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The returns for 2023–2025 all give MONROVIA as port of registry.

Its 5,411 t of CO₂ for 2025 is 32% 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 252.0 kg CO₂, 37% below the type median of 403.2 kg. It logged 1,958 hours at sea against a median of 2,030 hours for its type that year. 11.3% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 3 years with reported emissions, the highest was 2024 (9,934 t) and the lowest 2023 (4,190 t). Its efficiency percentile within the type went from 98 in 2024 to 94 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 29.1% higher than in 2023, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 45.5% while distance sailed fell 44.2%and CO₂ per nautical mile fell 2.3%.That points mainly to how much the vessel sailed, rather than the other.
