SHENLONG 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 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. Its MRV returns name it SHENLONG SPIRIT for 2018–2024 and SHENLONG for 2025. The reported port of registry changed: Nassau (2018–2024), then MONROVIA (2025).
Its 4,530 t of CO₂ for 2025 is 43% 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 469.4 kg CO₂, 16% above the type median of 403.2 kg. It logged 1,025 hours at sea against a median of 2,030 hours for its type that year. 7.4% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2023 (13,886 t) and the lowest 2018 (2,334 t). Its efficiency percentile within the type went from 9 in 2018 to 25 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 369 of 1,448 qualifying oil tankers by EEOI, at the 25th 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 801,778,761 tonne-miles over 9,651 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 94.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.
From 2024 to 2025, emissions fell 24.1% while distance sailed fell 24.7%and CO₂ per nautical mile rose 0.8%.That points mainly to how much the vessel sailed, rather than the other.
