ALKIMOS against its type
Built in 2015, it is 5 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 9,366 gross tonnage it is smaller than 96% of the other 2,841 oil tankers with a recorded tonnage. It is one of 237 oil tankers here under the Singapore flag, 6.7% of the 3,548 on the register. Its MRV returns name it ALKIMOS for 2018–2020 and SRIWANGI III for 2024–2025. The returns for 2024–2025 all give Singapore as port of registry.
Its 6,417 t of CO₂ for 2025 is 19% 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 203.2 kg CO₂, 50% below the type median of 403.2 kg. It logged 3,320 hours at sea against a median of 2,030 hours for its type that year. 13.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2019 (8,519 t) and the lowest 2020 (1,318 t). Its efficiency percentile within the type went from 81 in 2018 to 83 in 2019 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 134.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 73.4% and CO₂ per nautical mile fell 4.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
