NISSOS SERIFOS against its type

Built in 2012, it is 2 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 61,242 gross tonnage it is larger than 54% 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 563 other vessels here, 217 of them oil tankers. The returns for 2018–2025 all give Majuro as port of registry.

Its 9,449 t of CO₂ for 2025 is 19% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 484.6 kg CO₂, 20% above the type median of 403.2 kg. It logged 1,977 hours at sea against a median of 2,030 hours for its type that year. 11.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2018 (21,597 t) and the lowest 2023 (2,108 t). Its efficiency percentile within the type went from 64 in 2018 to 82 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 56.2% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 40.2% while distance sailed fell 38.6%and CO₂ per nautical mile fell 2.6%.That points mainly to how much the vessel sailed, rather than the other.
