AAL DALIAN against its type

Built in 2013, it is 6 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 23,930 gross tonnage it is larger than 90% 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. Columbia Shipmanagement Ltd. is linked to 43 vessels on this register. The returns for 2018–2025 all give Monrovia as port of registry.

Its 1,573 t of CO₂ for 2025 is 44% below 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 275.2 kg CO₂, 2.3 times the type median of 122.2 kg. It logged 462 hours at sea against a median of 3,044 hours for its type that year. 8.9% 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 2020 (8,895 t) and the lowest 2018 (369 t). Its efficiency percentile within the type went from 63 in 2022 to 82 in 2024 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024

Position 262 of 321 qualifying general cargo ships by EEOI, at the 82nd percentile. The dashed line is the type median, 23.6; this vessel reported 37.6.

0255075100more efficientless efficientThis vessel: 82nd percentile, EEOI 37.6

Across the 36 ranked vessels operated by Columbia Shipmanagement Ltd., the median percentile is 66. This vessel is less efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 107,452,058 tonne-miles over 15,342 nautical miles.

Reported CO₂ by year

2018: 369 t20183692020: 8,895 t20202021: 1,380 t20212022: 6,942 t20222023: 2,740 t20232024: 4,046 t20242025: 1,573 t20251,573

Reported CO₂ in 2025 was 326.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.

From 2024 to 2025, emissions fell 61.1% and CO₂ per nautical mile rose 4.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
