ASPHALT SYNERGY against its type

Built in 2018, it is 8 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 26,118 gross tonnage it is smaller than 86% 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 same builder is recorded for 40 other vessels here, one of them an oil tanker. The returns for 2018–2025 all give Majuro as port of registry.

Its 13,090 t of CO₂ for 2025 is 1.7 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 290.2 kg CO₂, 28% below the type median of 403.2 kg. It logged 4,290 hours at sea against a median of 2,030 hours for its type that year. 5.6% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2018 (17,035 t) and the lowest 2019 (8,089 t). Its efficiency percentile within the type was 87 in both 2018 and 2025. Of the 8 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,260 of 1,448 qualifying oil tankers by EEOI, at the 87th percentile. The dashed line is the type median, 7.5; this vessel reported 15.4.

EEOI divides emissions by transport work, which for this vessel and year was 847,233,657 tonne-miles over 45,100 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 23.2% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 8.0% while distance sailed rose 0.8%and CO₂ per nautical mile rose 7.2%.That points mainly to how efficiently it sailed, rather than the other.
