CONSTELLATION 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 41,994 gross tonnage it is smaller than 65% 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. The returns for 2019–2025 all give Majuro as port of registry.

Its 9,639 t of CO₂ for 2024 is 18% above the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 383.8 kg CO₂, close to the type median of 408.2 kg. It logged 2,166 hours at sea against a median of 2,020 hours for its type that year. 7.1% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 5 years with reported emissions, the highest was 2024 (9,639 t) and the lowest 2023 (4,093 t). Its efficiency percentile within the type went from 65 in 2019 to 66 in 2024 (lower is more efficient). Of the 3 comparable vessels listed below with a 2024 return, 2 reported a lower CO₂ per nautical mile than this vessel.

No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024

Position 1,038 of 1,566 qualifying oil tankers by EEOI, at the 66th percentile. The dashed line is the type median, 7.6; this vessel reported 9.1.

EEOI divides emissions by transport work, which for this vessel and year was 1,062,726,571 tonne-miles over 25,117 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2024 was 9.9% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2023 to 2024, emissions rose 135.5% while distance sailed rose 111.7%and CO₂ per nautical mile rose 11.2%.That points mainly to how much the vessel sailed, rather than the other.
