DANOS Z against its type

Built in 2001, it is 11 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 27,011 gross tonnage it is smaller than 74% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,601 bulk carriers here under the Panama flag, 19.7% of the 8,138 on the register. The same builder is recorded for 83 other vessels here, 71 of them bulk carriers. Its MRV returns name it DANOS Z for 2018–2019, VIVA UNITY for 2022–2023 and ONE UNION for 2024. The reported port of registry changed: Monrovia (2018–2019), then PANAMA (2022–2024).

Its 2,754 t of CO₂ for 2024 is 18% below the median of 3,377 t among the 3,676 bulk carriers on this register that reported for 2024. Per nautical mile it emitted 269.9 kg CO₂, close to the type median of 264.0 kg. It logged 955 hours at sea against a median of 1,238 hours for its type that year. 0.9% of its 2024 emissions were at berth; the median for bulk carriers was 2.9%. Across 5 years with reported emissions, the highest was 2024 (2,754 t) and the lowest 2022 (932 t). Its efficiency percentile within the type went from 67 in 2018 to 50 in 2024 (lower is more efficient).

Efficiency against its own type2024

Position 1,440 of 2,858 qualifying bulk carriers by EEOI, at the 50th percentile. The dashed line is the type median, 7.9; this vessel reported 7.9.

EEOI divides emissions by transport work, which for this vessel and year was 346,818,640 tonne-miles over 10,204 nautical miles.

Reported CO₂ in 2024 was 41.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.

From 2023 to 2024, emissions rose 50.0% and CO₂ per nautical mile fell 2.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 5 MRV reporting years, an efficiency ranking, 5 of 5 vessel particulars and a name history. Not found in the sources for this vessel: 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.
