WEN ZHU HAI against its type

Built in 2008, it is 4 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 40,896 gross tonnage it is larger than 64% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 137 bulk carriers here under the China flag, 1.7% of the 8,138 on the register. The same builder is recorded for 98 other vessels here, 49 of them bulk carriers. The returns for 2019–2025 all give Tianjin as port of registry.

Its 2,785 t of CO₂ for 2025 is 14% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 306.7 kg CO₂, 18% above the type median of 260.7 kg. It logged 805 hours at sea against a median of 1,200 hours for its type that year. 6.3% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 7 years with reported emissions, the highest was 2023 (8,121 t) and the lowest 2019 (2,401 t). Its efficiency percentile within the type went from 35 in 2019 to 72 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 16.0% higher than in 2019, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 45.3% while distance sailed fell 47.8%and CO₂ per nautical mile rose 4.8%.That points mainly to how much the vessel sailed, rather than the other.
