BLUE NOVA against its type
Built in 2011, it is 1 year newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 157,225 gross tonnage it is larger than 91% 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 2020–2025 all give Monrovia as port of registry.
Its 27,640 t of CO₂ for 2025 is 3.5 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 769.0 kg CO₂, 1.9 times the type median of 403.2 kg. It logged 3,337 hours at sea against a median of 2,030 hours for its type that year. 6.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2022 (36,733 t) and the lowest 2020 (9,380 t). Its efficiency percentile within the type went from 1 in 2020 to 18 in 2025 (lower is more efficient). Of the 2 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 264 of 1,448 qualifying oil tankers by EEOI, at the 18th percentile. The dashed line is the type median, 7.5; this vessel reported 5.0.
EEOI divides emissions by transport work, which for this vessel and year was 5,506,057,769 tonne-miles over 35,945 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 194.7% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions fell 3.1% while distance sailed fell 13.9%and CO₂ per nautical mile rose 12.5%.
