MANISA BALU against its type
Built in 2008, it is 1 year newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 5,629 gross tonnage it is smaller than 56% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 187 general cargo ships here under the Portugal flag, 6.1% of the 3,081 on the register. The same builder is recorded for 127 other vessels here, 52 of them general cargo ships. The reported port of registry changed: Valletta (2018–2022), then Madeira (2023–2025).
Its 4,868 t of CO₂ for 2025 is 1.7 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 141.0 kg CO₂, 15% above the type median of 122.2 kg. It logged 3,900 hours at sea against a median of 3,044 hours for its type that year. 9.6% 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 2023 (6,619 t) and the lowest 2022 (4,295 t). Its efficiency percentile within the type went from 96 in 2023 to 61 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.
