MAERSK KATALIN against its type

Built in 2012, it is 2 years newer than the median oil tanker on this register, which was built in 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 237 oil tankers here under the Singapore flag, 6.7% 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 2018–2023 all give Singapore as port of registry.

Its 7,010 t of CO₂ for 2023 is close to the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 269.3 kg CO₂, 34% below the type median of 408.5 kg. It logged 2,269 hours at sea against a median of 1,807 hours for its type that year. 10.2% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 6 years with reported emissions, the highest was 2020 (14,678 t) and the lowest 2023 (7,010 t). Its efficiency percentile within the type went from 58 in 2018 to 82 in 2023 (lower is more efficient). The one sister ship listed below with a 2023 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2023

Position 1,333 of 1,615 qualifying oil tankers by EEOI, at the 82nd percentile. The dashed line is the type median, 8.0; this vessel reported 13.6.

EEOI divides emissions by transport work, which for this vessel and year was 517,329,889 tonne-miles over 26,030 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2023 was 27.9% lower than in 2018, for EU/EEA voyages only.

From 2022 to 2023, emissions fell 33.6% while distance sailed fell 27.3%and CO₂ per nautical mile fell 8.6%.That points mainly to how much the vessel sailed, rather than the other.

Where the 2023 emissions occurred

Laden voyages2023

CO₂ on laden voyages: 4,049 t, 58% of total
Fuel, laden: 1,273 t
CO₂ per nm, laden: 254.1 kg

The rest of the 2023 total was emitted on ballast legs or at berth.
