DILONG SPIRIT against its type
Built in 2009, it is 1 year older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 85,030 gross tonnage it is larger than 85% of the other 2,841 oil tankers with a recorded tonnage. It is one of 180 oil tankers here under the Bahamas flag, 5.1% of the 3,548 on the register. The returns for 2018–2025 all give Nassau as port of registry.
Its 11,145 t of CO₂ for 2025 is 41% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 435.7 kg CO₂, close to the type median of 403.2 kg. It logged 2,478 hours at sea against a median of 2,030 hours for its type that year. 4.5% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2018 (14,286 t) and the lowest 2024 (2,378 t). Its efficiency percentile within the type went from 12 in 2018 to 14 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 196 of 1,448 qualifying oil tankers by EEOI, at the 14th percentile. The dashed line is the type median, 7.5; this vessel reported 4.7.
EEOI divides emissions by transport work, which for this vessel and year was 2,356,300,211 tonne-miles over 25,581 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 22.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions rose 368.6% while distance sailed rose 422.2%and CO₂ per nautical mile fell 10.3%.That points mainly to how much the vessel sailed, rather than the other.
