MAERSK PATRAS against its type

Built in 1998, it is 10 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 31,333 gross tonnage it is smaller than 63% of the other 3,000 container ships with a recorded tonnage. It is one of 362 container ships here under the Singapore flag, 10.4% of the 3,495 on the register. The same builder is recorded for 16 other vessels here, all of them container ships. The returns for 2018–2022 all give Singapore as port of registry.

Its 13,545 t of CO₂ for 2022 is 12% below the median of 15,388 t among the 1,858 container ships on this register that reported for 2022. Per nautical mile it emitted 381.2 kg CO₂, 29% below the type median of 539.7 kg. It logged 2,925 hours at sea against a median of 2,699 hours for its type that year. 2.8% of its 2022 emissions were at berth; the median for container ships was 4.2%. Across 5 years with reported emissions, the highest was 2021 (36,956 t) and the lowest 2022 (13,545 t). Its efficiency percentile within the type went from 48 in 2018 to 52 in 2022 (lower is more efficient). Of the 2 sister ships listed below with a 2022 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022

Position 824 of 1,589 qualifying container ships by EEOI, at the 52nd percentile. The dashed line is the type median, 16.9; this vessel reported 17.6.

EEOI divides emissions by transport work, which for this vessel and year was 770,476,109 tonne-miles over 35,534 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2022 was 57.0% lower than in 2018, for EU/EEA voyages only.

From 2021 to 2022, emissions fell 63.3% while distance sailed fell 61.1%and CO₂ per nautical mile fell 5.7%.That points mainly to how much the vessel sailed, rather than the other.

Where the 2022 emissions occurred

Laden voyages2022

CO₂ on laden voyages: 13,172 t, 97% of total
Fuel, laden: 4,230 t
CO₂ per nm, laden: 370.7 kg

The rest of the 2022 total was emitted on ballast legs or at berth.
