PROSNA against its type

Built in 2012, it is 5 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 13,579 gross tonnage it is larger than 71% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 216 general cargo ships here under the Liberia flag, 7.0% of the 3,081 on the register. Its MRV returns name it PROSNA for 2018–2021, UNIVENTURE for 2022–2023 and VERACRUZ for 2024–2025. The reported port of registry changed: Monrovia (2018–2021), then ST.JOHN'S (2022), then Saint John's (2023), then MONROVIA (2024–2025).

Its 4,528 t of CO₂ for 2025 is 1.6 times the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 198.4 kg CO₂, 1.6 times the type median of 122.2 kg. It logged 1,901 hours at sea against a median of 3,044 hours for its type that year. 9.3% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2022 (5,418 t) and the lowest 2018 (1,132 t). Its efficiency percentile within the type went from 97 in 2019 to 65 in 2024 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024

Position 210 of 321 qualifying general cargo ships by EEOI, at the 65th percentile. The dashed line is the type median, 23.6; this vessel reported 29.8.

0255075100more efficientless efficientThis vessel: 65th percentile, EEOI 29.8

EEOI divides emissions by transport work, which for this vessel and year was 131,932,550 tonne-miles over 18,706 nautical miles.

Reported CO₂ in 2025 was 300.1% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 15.2% and CO₂ per nautical mile fell 5.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
