INGRID KNUTSEN against its type
Built in 2013, it is 3 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 66,038 gross tonnage it is larger than 68% of the other 2,841 oil tankers with a recorded tonnage. It is one of 11 oil tankers here under the United Kingdom flag, 0.3% of the 3,548 on the register. The same builder is recorded for 761 other vessels here, 193 of them oil tankers. Knutsen O.A.S. Shipping AS is linked to 4 vessels on this register.
Its 19,218 t of CO₂ for 2025 is 2.4 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 721.6 kg CO₂, 1.8 times the type median of 403.2 kg. It logged 3,824 hours at sea against a median of 2,030 hours for its type that year. 12.6% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2020 (28,132 t) and the lowest 2021 (17,072 t). Its efficiency percentile within the type went from 93 in 2018 to 91 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,320 of 1,448 qualifying oil tankers by EEOI, at the 91st percentile. The dashed line is the type median, 7.5; this vessel reported 19.3.
EEOI divides emissions by transport work, which for this vessel and year was 994,191,930 tonne-miles over 26,633 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 23.4% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 7.0% while distance sailed fell 3.2%and CO₂ per nautical mile rose 10.6%.That points mainly to how efficiently it sailed, rather than the other.
