MARS SUN against its type

Built in 2006, it is 4 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 59,158 gross tonnage it is smaller than 50% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 103 other vessels here, 28 of them oil tankers. The returns for 2019–2022 all give Monrovia as port of registry.

Its 10,136 t of CO₂ for 2022 is 41% above the median of 7,189 t among the 1,939 oil tankers on this register that reported for 2022. Per nautical mile it emitted 393.1 kg CO₂, close to the type median of 415.9 kg. It logged 3,478 hours at sea against a median of 1,731 hours for its type that year. 7.7% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Across 4 years with reported emissions, the highest was 2020 (16,509 t) and the lowest 2019 (5,891 t). Its efficiency percentile within the type went from 1 in 2019 to 55 in 2022 (lower is more efficient). Of the 3 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 979 of 1,771 qualifying oil tankers by EEOI, at the 55th percentile. The dashed line is the type median, 8.0; this vessel reported 8.5.

EEOI divides emissions by transport work, which for this vessel and year was 1,189,677,230 tonne-miles over 25,788 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2022 was 72.1% higher than in 2019, for EU/EEA voyages only.

From 2021 to 2022, emissions fell 36.7% while distance sailed fell 31.7%and CO₂ per nautical mile fell 7.4%.That points mainly to how much the vessel sailed, rather than the other.
