JAMNO against its type

Built in 2018, it is 11 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 22,982 gross tonnage it is larger than 86% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 146 general cargo ships here under the Bahamas flag, 4.7% of the 3,081 on the register. The same builder is recorded for 211 other vessels here, 13 of them general cargo ships. Polsteam is linked to 6 vessels on this register. The returns for 2019–2025 all give Nassau as port of registry.

Its 6,905 t of CO₂ for 2025 is 2.4 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 192.7 kg CO₂, 1.6 times the type median of 122.2 kg. It logged 3,510 hours at sea against a median of 3,044 hours for its type that year. 8.3% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2024 (7,677 t) and the lowest 2020 (4,696 t). Of the 7 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2019

Position 2,586 of 3,161 qualifying bulk carriers by EEOI, at the 82nd percentile. The dashed line is the type median, 8.1; this vessel reported 11.6.

0255075100more efficientless efficientThis vessel: 82nd percentile, EEOI 11.6

Across the 6 ranked vessels operated by Polsteam, the median percentile is 79. This vessel is less efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 454,605,512 tonne-miles over 23,602 nautical miles.

Reported CO₂ in 2025 was 30.8% higher than in 2019, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 10.1% and CO₂ per nautical mile fell 10.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
