AK DISCOVERY against its type
Built in 2001, it is 6 years older than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 5,381 gross tonnage it is smaller than 58% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 20 general cargo ships here under the Sierra Leone flag, 0.6% of the 3,081 on the register. The reported port of registry changed: Panama (2021), then bridgetown (2023), then FREETOWN (2024).
Its 2,258 t of CO₂ for 2024 is 44% below the median of 4,046 t among the 1,395 general cargo ships on this register that reported for 2024. Per nautical mile it emitted 101.5 kg CO₂, 46% below the type median of 187.0 kg. It logged 2,312 hours at sea against a median of 2,074 hours for its type that year. 8.5% of its 2024 emissions were at berth; the median for general cargo ships was 3.9%. Across 4 years with reported emissions, the highest was 2023 (2,987 t) and the lowest 2022 (2,088 t). Its efficiency percentile within the type went from 29 in 2021 to 56 in 2024 (lower is more efficient).
