SAMC SWAN against its type

Built in 2019, it is 9 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 6,052 gross tonnage it is smaller than 94% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 65 chemical tankers here under the Hong Kong flag, 2.8% of the 2,344 on the register. The returns for 2022–2025 all give HONG KONG as port of registry.

Its 1,455 t of CO₂ for 2025 is 74% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 116.4 kg CO₂, 53% below the type median of 250.2 kg. It logged 1,310 hours at sea against a median of 2,106 hours for its type that year. 8.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2022 (4,555 t) and the lowest 2024 (738 t). Its efficiency percentile within the type went from 76 in 2022 to 75 in 2023 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 68.1% lower than in 2022, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 97.2% and CO₂ per nautical mile rose 16.0%.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 4 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.
