SEA DUCK against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 8,247 gross tonnage it is smaller than 88% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The reported port of registry changed: Valletta (2021–2023), then Monrovia (2024–2025).
Its 2,193 t of CO₂ for 2025 is 60% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 205.6 kg CO₂, 18% below the type median of 250.2 kg. It logged 907 hours at sea against a median of 2,109 hours for its type that year. 8.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2022 (8,701 t) and the lowest 2025 (2,193 t). Its efficiency percentile within the type went from 74 in 2021 to 100 in 2024 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 22.4% lower than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 68.4% and CO₂ per nautical mile fell 5.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
