KIRSTEN MAERSK against its type

Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). At 24,463 gross tonnage it is smaller than 88% of the other 2,841 oil tankers with a recorded tonnage. It is one of 72 oil tankers here under the Denmark flag, 2.0% of the 3,548 on the register. The same builder is recorded for 192 other vessels here, 71 of them oil tankers. The returns for 2018–2025 all give Copenhagen as port of registry.

Its 9,165 t of CO₂ for 2025 is 16% 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 293.9 kg CO₂, 27% below the type median of 403.2 kg. It logged 2,657 hours at sea against a median of 2,030 hours for its type that year. 12.9% 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 (11,917 t) and the lowest 2019 (1,095 t). Its efficiency percentile within the type went from 76 in 2020 to 89 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 144.3% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 16.6% while distance sailed fell 11.5%and CO₂ per nautical mile fell 5.8%.That points mainly to how much the vessel sailed, rather than the other.
