ZUMA against its type

Built in 2005, it is 5 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 58,418 gross tonnage it is smaller than 51% of the other 2,841 oil tankers with a recorded tonnage. It is one of 215 oil tankers here under the Greece flag, 6.1% of the 3,548 on the register. The same builder is recorded for 194 other vessels here, 56 of them oil tankers. The reported port of registry changed: Piraeus (2018–2021), then Monrovia (2022–2023).

Its 30,178 t of CO₂ for 2023 is 4.0 times the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 391.5 kg CO₂, close to the type median of 408.5 kg. It logged 6,555 hours at sea against a median of 1,807 hours for its type that year. 5.4% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 6 years with reported emissions, the highest was 2023 (30,178 t) and the lowest 2020 (5,176 t). Its efficiency percentile within the type went from 3 in 2018 to 64 in 2023 (lower is more efficient). Of the 2 sister ships listed below with a 2023 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023

Position 1,033 of 1,615 qualifying oil tankers by EEOI, at the 64th percentile. The dashed line is the type median, 8.0; this vessel reported 9.5.

EEOI divides emissions by transport work, which for this vessel and year was 3,186,725,449 tonne-miles over 77,082 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2023 was 146.4% higher than in 2018, for EU/EEA voyages only.

From 2022 to 2023, emissions rose 187.2% while distance sailed rose 229.7%and CO₂ per nautical mile fell 12.9%.That points mainly to how much the vessel sailed, rather than the other.

Where the 2023 emissions occurred

Laden voyages2023

CO₂ on laden voyages: 15,704 t, 52% of total
Fuel, laden: 5,029 t
CO₂ per nm, laden: 368.6 kg

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