NISSOS SIKINOS against its type

Built in 2020, it is 10 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 81,502 gross tonnage it is larger than 77% 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 461 other vessels here, 179 of them oil tankers. The returns for 2021–2025 all give Majuro as port of registry.

Its 13,465 t of CO₂ for 2025 is 1.7 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 472.7 kg CO₂, 17% above the type median of 403.2 kg. It logged 2,429 hours at sea against a median of 2,030 hours for its type that year. 7.2% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2024 (15,368 t) and the lowest 2021 (2,627 t). Its efficiency percentile within the type went from 11 in 2021 to 30 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 412.5% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2024 to 2025, emissions fell 12.4% while distance sailed fell 16.1%and CO₂ per nautical mile rose 4.5%.That points mainly to how much the vessel sailed, rather than the other.
