ETERNAL DILIGENCE 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 40,803 gross tonnage it is smaller than 66% 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 103 other vessels here, 61 of them oil tankers. Its MRV returns name it ETERNAL DILIGENCE for 2018–2019 and REGINA for 2020–2021. The reported port of registry changed: PANAMA (2018–2019), then Monrovia (2020–2021).
Its 2,689 t of CO₂ for 2021 is 65% below the median of 7,717 t among the 1,777 oil tankers on this register that reported for 2021. Per nautical mile it emitted 375.6 kg CO₂, close to the type median of 409.1 kg. It logged 500 hours at sea against a median of 1,921 hours for its type that year. 3.2% of its 2021 emissions were at berth; the median for oil tankers was 8.8%. Across 4 years with reported emissions, the highest was 2020 (8,069 t) and the lowest 2018 (2,280 t). Its efficiency percentile within the type went from 30 in 2019 to 74 in 2021 (lower is more efficient).

Efficiency against its own type2021
Position 1,217 of 1,636 qualifying oil tankers by EEOI, at the 74th percentile. The dashed line is the type median, 8.4; this vessel reported 12.2.
EEOI divides emissions by transport work, which for this vessel and year was 219,896,975 tonne-miles over 7,160 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 17.9% higher than in 2018, for EU/EEA voyages only.
From 2020 to 2021, emissions fell 66.7% while distance sailed fell 61.2%and CO₂ per nautical mile fell 14.2%.That points mainly to how much the vessel sailed, rather than the other.
