ARKLOW DAY against its type
Built in 2011, it is 4 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 128 general cargo ships here under the Cyprus flag, 4.2% 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 DAY for 2018–2021 and HELME for 2023–2025. The reported port of registry changed: Arklow (2018–2019), then Rotterdam (2020–2021), then Limassol (2023–2025).
Its 6,623 t of CO₂ for 2025 is 2.3 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 126.2 kg CO₂, close to the type median of 122.2 kg. It logged 4,378 hours at sea against a median of 3,044 hours for its type that year. 3.0% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2020 (6,632 t) and the lowest 2024 (5,405 t). Its efficiency percentile within the type went from 41 in 2018 to 49 in 2021 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2021
Position 159 of 326 qualifying general cargo ships by EEOI, at the 49th percentile. The dashed line is the type median, 22.6; this vessel reported 22.4.
EEOI divides emissions by transport work, which for this vessel and year was 276,501,340 tonne-miles over 39,885 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 9.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions rose 22.5% and CO₂ per nautical mile rose 3.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
