SONANGOL KALANDULA 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 83,753 gross tonnage it is larger than 81% 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 same builder is recorded for 660 other vessels here, 159 of them oil tankers. The returns for 2018–2025 all give NASSAU as port of registry.
Its 17,940 t of CO₂ for 2025 is 2.3 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 543.9 kg CO₂, 35% above the type median of 403.2 kg. It logged 3,177 hours at sea against a median of 2,030 hours for its type that year. 10.6% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2025 (17,940 t) and the lowest 2018 (1,692 t). Its efficiency percentile within the type went from 37 in 2019 to 59 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 856 of 1,448 qualifying oil tankers by EEOI, at the 59th percentile. The dashed line is the type median, 7.5; this vessel reported 8.2.
EEOI divides emissions by transport work, which for this vessel and year was 2,190,434,676 tonne-miles over 32,985 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 960.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2024, so the series has gaps.
From 2023 to 2025, emissions rose 49.2% while distance sailed rose 7.2%and CO₂ per nautical mile rose 39.1%.That points mainly to how efficiently it sailed, rather than the other.
