COETIVY 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). At 28,725 gross tonnage it is smaller than 81% 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 307 other vessels here, 48 of them oil tankers. Its MRV returns name it COETIVY for 2024 and YUME for 2025. The reported port of registry changed: Majuro (2024), then Monrovia (2025).
Its 2,150 t of CO₂ for 2025 is 73% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 255.0 kg CO₂, 37% below the type median of 403.2 kg. It logged 748 hours at sea against a median of 2,030 hours for its type that year. 1.5% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Of the 3 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 812 of 1,448 qualifying oil tankers by EEOI, at the 56th percentile. The dashed line is the type median, 7.5; this vessel reported 7.9.
EEOI divides emissions by transport work, which for this vessel and year was 271,401,515 tonne-miles over 8,431 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 50.8% lower than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 50.8% and CO₂ per nautical mile fell 9.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
