PATROKLOS against its type

Built in 2017, it is 5 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 44,043 gross tonnage it is larger than 76% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,589 bulk carriers here under the Liberia flag, 19.5% of the 8,138 on the register. The returns for 2018–2025 all give Monrovia as port of registry.

Its 5,553 t of CO₂ for 2025 is 1.7 times the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 318.9 kg CO₂, 22% above the type median of 260.7 kg. It logged 1,578 hours at sea against a median of 1,199 hours for its type that year. 3.6% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2020 (15,433 t) and the lowest 2019 (1,533 t). Its efficiency percentile within the type went from 25 in 2018 to 53 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,721 of 3,241 qualifying bulk carriers by EEOI, at the 53rd percentile. The dashed line is the type median, 7.6; this vessel reported 7.8.

EEOI divides emissions by transport work, which for this vessel and year was 710,048,593 tonne-miles over 17,410 nautical miles.

Reported CO₂ by year

2018: 5,603 t20185,6032019: 1,533 t20192020: 15,433 t20202021: 13,798 t20212024: 4,554 t20242025: 5,553 t20255,553

Reported CO₂ in 2025 was 0.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.

From 2024 to 2025, emissions rose 21.9% while distance sailed rose 27.2%and CO₂ per nautical mile fell 4.1%.That points mainly to how much the vessel sailed, rather than the other.
