MAERSK PRINCESS 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 61,724 gross tonnage it is larger than 56% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. Its MRV returns name it MAERSK PRINCESS for 2018–2019 and SRI ASIH for 2020–2021. The reported port of registry changed: Singapore (2018–2019), then Majuro (2020–2021).

Its 7,195 t of CO₂ for 2021 is close to the median of 7,717 t among the 1,777 oil tankers on this register that reported for 2021. Per nautical mile it emitted 518.9 kg CO₂, 27% above the type median of 409.1 kg. It logged 1,894 hours at sea against a median of 1,921 hours for its type that year. 9.2% of its 2021 emissions were at berth; the median for oil tankers was 8.8%. Across 4 years with reported emissions, the highest was 2020 (11,666 t) and the lowest 2021 (7,195 t). Its efficiency percentile within the type went from 81 in 2018 to 37 in 2021 (lower is more efficient). Of the 2 comparable vessels listed below with a 2021 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2021 was 3.6% lower than in 2018, for EU/EEA voyages only.

From 2020 to 2021, emissions fell 38.3% while distance sailed fell 16.3%and CO₂ per nautical mile fell 26.3%.That points mainly to how efficiently it sailed, rather than the other.
