EXPLORER 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 84,844 gross tonnage it is larger than 84% 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 461 other vessels here, 179 of them oil tankers. The reported port of registry changed: Piraeus (2018–2021), then Monrovia (2022–2025).
Its 14,016 t of CO₂ for 2025 is 1.8 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 463.4 kg CO₂, 15% above the type median of 403.2 kg. It logged 2,609 hours at sea against a median of 2,030 hours for its type that year. 6.4% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2024 (15,554 t) and the lowest 2019 (4,569 t). Its efficiency percentile within the type went from 7 in 2018 to 6 in 2025 (lower is more efficient).

Efficiency against its own type2025
Position 80 of 1,448 qualifying oil tankers by EEOI, at the 6th percentile. The dashed line is the type median, 7.5; this vessel reported 3.9.
EEOI divides emissions by transport work, which for this vessel and year was 3,575,390,306 tonne-miles over 30,245 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 85.6% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 9.9% while distance sailed fell 17.0%and CO₂ per nautical mile rose 8.5%.That points mainly to how much the vessel sailed, rather than the other.
