ADVANTAGE PORTO CERVO 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 46,509 gross tonnage it is smaller than 58% 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 118 other vessels here, 4 of them oil tankers. Its MRV returns name it NAUTICAL SARAH for 2019–2022 and ADVANTAGE PORTO CERVO for 2024–2025. The reported port of registry changed: MONROVIA (2019–2022), then MAJURO (2024–2025).
Its 1,184 t of CO₂ for 2025 is 85% 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 346.9 kg CO₂, 14% below the type median of 403.2 kg. It logged 490 hours at sea against a median of 2,030 hours for its type that year. 7.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2024 (14,759 t) and the lowest 2020 (813 t). Its efficiency percentile within the type went from 21 in 2019 to 33 in 2024 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 82.0% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 92.0% and CO₂ per nautical mile fell 7.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
