ARKLOW DALE against its type
Built in 2010, it is 3 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 6,687 gross tonnage it is larger than 53% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 67 general cargo ships here under the Palau flag, 2.2% of the 3,081 on the register. The same builder is recorded for 98 other vessels here, all of them general cargo ships. Its MRV returns name it ARKLOW DALE for 2018–2021, LONGWOLF for 2022–2024 and SEAWOLF for 2025. The reported port of registry changed: Arklow (2018–2019), then Rotterdam (2020–2021), then Groningen (2022–2024), then MALAKAL HARBOR (2025).
Its 3,266 t of CO₂ for 2025 is 16% above 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 172.2 kg CO₂, 41% above the type median of 122.2 kg. It logged 1,959 hours at sea against a median of 3,044 hours for its type that year. 7.3% 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 2021 (7,096 t) and the lowest 2025 (3,266 t). Its efficiency percentile within the type went from 27 in 2018 to 50 in 2021 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2021
Position 165 of 326 qualifying general cargo ships by EEOI, at the 50th percentile. The dashed line is the type median, 22.6; this vessel reported 22.7.
EEOI divides emissions by transport work, which for this vessel and year was 312,736,007 tonne-miles over 47,640 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 46.9% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 48.4% and CO₂ per nautical mile rose 11.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
