FAIRCHEM KISO against its type

Built in 2011, it is 1 year newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 11,653 gross tonnage it is smaller than 95% 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. The same builder is recorded for 17 other vessels here. Its MRV returns name it FAIRCHEM KISO for 2018–2022 and NV ATHENA for 2023–2025. The reported port of registry changed: MAJURO (2018–2022), then SINGAPORE (2023–2025).

Its 1,535 t of CO₂ for 2025 is 81% 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 184.5 kg CO₂, 54% below the type median of 403.2 kg. It logged 823 hours at sea against a median of 2,030 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2020 (9,980 t) and the lowest 2025 (1,535 t). Its efficiency percentile within the type went from 41 in 2018 to 93 in 2024 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 61.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.

From 2024 to 2025, emissions fell 66.7% and CO₂ per nautical mile fell 1.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 7 MRV reporting years, 5 of 5 vessel particulars, a name history and a licensed photograph. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
