CASPIAN HARMONY against its type

Built in 2016, it is 9 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 22,362 gross tonnage it is larger than 84% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 73 general cargo ships here under the Hong Kong flag, 2.4% of the 3,081 on the register. The returns for 2018–2025 all give Hong Kong as port of registry.

Its 6,971 t of CO₂ for 2025 is 2.5 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 213.0 kg CO₂, 1.7 times the type median of 122.2 kg. It logged 3,349 hours at sea against a median of 3,044 hours for its type that year. 3.4% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 5 years with reported emissions, the highest was 2018 (7,267 t) and the lowest 2024 (1,425 t). Of the 7 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year

Reported CO₂ in 2025 was 4.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2022, 2023, so the series has gaps.

From 2024 to 2025, emissions rose 389.2% and CO₂ per nautical mile fell 18.5%.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 and 4 of 5 vessel particulars. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, a name history, 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.
