DELTA POSEIDON against its type
Built in 2011, it is 1 year newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 81,360 gross tonnage it is larger than 74% of the other 2,841 oil tankers with a recorded tonnage. It is one of 289 oil tankers here under the Malta flag, 8.1% of the 3,548 on the register. The same builder is recorded for 461 other vessels here, 179 of them oil tankers. The reported port of registry changed: Piraeus (2018–2023), then Valletta (2024–2025).
Its 7,890 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 521.6 kg CO₂, 29% above the type median of 403.2 kg. It logged 1,410 hours at sea against a median of 2,030 hours for its type that year. 5.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2024 (15,734 t) and the lowest 2019 (2,257 t). Its efficiency percentile within the type went from 6 in 2019 to 27 in 2025 (lower is more efficient). Of the 2 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 388 of 1,448 qualifying oil tankers by EEOI, at the 27th percentile. The dashed line is the type median, 7.5; this vessel reported 5.7.
EEOI divides emissions by transport work, which for this vessel and year was 1,374,527,875 tonne-miles over 15,125 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 249.6% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 49.9% while distance sailed fell 51.0%and CO₂ per nautical mile rose 2.3%.That points mainly to how much the vessel sailed, rather than the other.
