CHELSEA-4 against its type
Built in 2007, it is the same age as the median general cargo ship on this register (build year 2007, 2,852 vessels with a known build year). At 5,184 gross tonnage it is smaller than 61% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 34 general cargo ships here under the Comoros flag, 1.1% of the 3,081 on the register. The reported port of registry changed: Valletta (2018–2020), then Malakal Harbor (2021–2024), then Moroni (2025).
Its 810 t of CO₂ for 2025 is 71% 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 91.9 kg CO₂, 25% below the type median of 122.2 kg. It logged 1,178 hours at sea against a median of 3,044 hours for its type that year. 5.9% 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 2018 (1,120 t) and the lowest 2024 (30 t). Of the 5 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.
