DARK OCEAN against its type
Built in 2000, it is 8 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 8,737 gross tonnage it is smaller than 95% of the other 3,000 container ships with a recorded tonnage. It is one of 2 container ships here under the Belize flag, 0.1% of the 3,495 on the register. The same builder is recorded for 80 other vessels here, 41 of them container ships. Its MRV returns name it IAPETOS for 2018–2023 and DARK OCEAN for 2024–2025. The reported port of registry changed: Piraeus (2018–2023), then Belize City (2024–2025).
Its 235 t of CO₂ for 2024 is 99% below the median of 17,769 t among the 2,101 container ships on this register that reported for 2024. Per nautical mile it emitted 394.0 kg CO₂, 25% below the type median of 528.5 kg. It logged 89 hours at sea against a median of 3,325 hours for its type that year. 40.8% of its 2024 emissions were at berth; the median for container ships was 2.8%. Across 7 years with reported emissions, the highest was 2020 (8,358 t) and the lowest 2024 (235 t). The one sister ship listed below with a 2024 return reported a lower CO₂ per nautical mile.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Reported CO₂ by year
Reported CO₂ in 2024 was 96.5% lower than in 2018, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 96.3% and CO₂ per nautical mile rose 90.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

This page draws on 8 MRV reporting years, 5 of 5 vessel particulars and a name history. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, a licensed photograph, a sanctions listing and US port state inspections.
Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
