ALPINE LIBERTY against its type

Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The same builder is recorded for 180 other vessels here, 51 of them oil tankers. The returns for 2019–2023 all give Majuro as port of registry.

Its 4,386 t of CO₂ for 2023 is 41% below the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 325.4 kg CO₂, 20% below the type median of 408.5 kg. It logged 1,115 hours at sea against a median of 1,807 hours for its type that year. 14.8% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 4 years with reported emissions, the highest was 2021 (6,671 t) and the lowest 2023 (4,386 t). Its efficiency percentile within the type went from 71 in 2019 to 60 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 981 of 1,615 qualifying oil tankers by EEOI, at the 60th percentile. The dashed line is the type median, 8.0; this vessel reported 9.1.

EEOI divides emissions by transport work, which for this vessel and year was 483,615,215 tonne-miles over 13,479 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2023 was 31.8% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2021 to 2023, emissions fell 34.2% while distance sailed fell 39.5%and CO₂ per nautical mile rose 8.7%.That points mainly to how much the vessel sailed, rather than the other.
