BASIC CHALLENGER against its type
Built in 2014, it is 7 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 22,866 gross tonnage it is larger than 86% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 181 general cargo ships here under the Marshall Islands flag, 5.9% of the 3,081 on the register. Its MRV returns name it BASIC CHALLENGER for 2021–2022 and CETUS SEI for 2024. The reported port of registry changed: PANAMA (2021–2022), then Majuro (2024).
Its 2,376 t of CO₂ for 2024 is 41% 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 211.0 kg CO₂, 13% above the type median of 187.0 kg. It logged 1,136 hours at sea against a median of 2,074 hours for its type that year. 1.3% of its 2024 emissions were at berth; the median for general cargo ships was 3.9%. Across 3 years with reported emissions, the highest was 2021 (2,700 t) and the lowest 2022 (1,309 t). The one comparable vessel listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2024 was 12.0% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2022 to 2024, emissions rose 81.6% and CO₂ per nautical mile fell 37.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
