ADVANTAGE PORTOFINO against its type
Built in 2018, it is 8 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 DEBORAH for 2019–2022 and ADVANTAGE PORTOFINO for 2023–2025. The reported port of registry changed: MONROVIA (2019–2022), then MAJURO (2023–2025).
Its 5,462 t of CO₂ for 2025 is 31% 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 315.2 kg CO₂, 22% below the type median of 403.2 kg. It logged 1,418 hours at sea against a median of 2,030 hours for its type that year. 4.2% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2022 (9,641 t) and the lowest 2023 (1,834 t). Its efficiency percentile within the type went from 76 in 2019 to 25 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.
