HERCULES 8000 against its type
Built in 2019, it is 9 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 6,082 gross tonnage it is smaller than 98% of the other 2,841 oil tankers with a recorded tonnage. It is one of 289 oil tankers here under the Malta flag, 8.1% of the 3,548 on the register. Its MRV returns name it HERCULES 8000 for 2019–2023 and VIGO for 2024–2025. The returns for 2019–2025 all give Valletta as port of registry.
Its 1,961 t of CO₂ for 2025 is 75% 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 204.9 kg CO₂, 49% below the type median of 403.2 kg. It logged 974 hours at sea against a median of 2,030 hours for its type that year. 44.6% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2020 (2,293 t) and the lowest 2023 (139 t). Of the 4 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 34.2% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions rose 4.7% and CO₂ per nautical mile fell 53.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
