ZHEN HUA 23 against its type

Built in 1986, it is 23 years older than the median vessel in the other ship types category on this register, which was built in 2009 (451 vessels with a known build year). At 37,879 gross tonnage it is larger than 90% of the other 436 vessels in the other ship types category with a recorded tonnage. It is one of 15 vessels in the other ship types category here under the Hong Kong flag, 3.0% of the 499 on the register. The same builder is recorded for 79 other vessels here, one of them a vessel in the other ship types category. The returns for 2018–2025 all give Hong Kong as port of registry.

Its 849 t of CO₂ for 2025 is 83% below the median of 5,122 t among the 335 vessels in the other ship types category on this register that reported for 2025. Per nautical mile it emitted 311.2 kg CO₂, 35% above the type median of 231.1 kg. It logged 242 hours at sea against a median of 2,231 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 5 years with reported emissions, the highest was 2018 (20,248 t) and the lowest 2025 (849 t). Its efficiency percentile within the type went from 61 in 2018 to 15 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Reported CO₂ in 2025 was 95.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.

From 2024 to 2025, emissions fell 55.7% and CO₂ per nautical mile fell 14.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
