SIGMA TRIUMPH 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 57,221 gross tonnage it is smaller than 54% 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 761 other vessels here, 193 of them oil tankers. The returns for 2019–2024 all give MONROVIA as port of registry.
Its 8,964 t of CO₂ for 2024 is close to the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 546.2 kg CO₂, 34% above the type median of 408.2 kg. It logged 1,311 hours at sea against a median of 2,020 hours for its type that year. 7.7% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 4 years with reported emissions, the highest was 2019 (14,031 t) and the lowest 2023 (2,568 t). Its efficiency percentile within the type went from 23 in 2019 to 80 in 2024 (lower is more efficient). Of the 3 sister ships listed below with a 2024 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 1,252 of 1,566 qualifying oil tankers by EEOI, at the 80th percentile. The dashed line is the type median, 7.6; this vessel reported 11.6.
EEOI divides emissions by transport work, which for this vessel and year was 774,093,264 tonne-miles over 16,410 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 36.1% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2023 to 2024, emissions rose 249.0% while distance sailed rose 268.4%and CO₂ per nautical mile fell 5.2%.That points mainly to how much the vessel sailed, rather than the other.
