MERCURIUS 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 6,957 gross tonnage it is smaller than 91% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 17 chemical tankers here under the Sweden flag, 0.7% of the 2,344 on the register. The returns for 2019–2025 all give DONSÖ as port of registry.

Its 6,763 t of CO₂ for 2025 is 22% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 138.9 kg CO₂, 44% below the type median of 250.2 kg. It logged 4,546 hours at sea against a median of 2,106 hours for its type that year. 15.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2021 (9,421 t) and the lowest 2024 (6,373 t). Its efficiency percentile within the type went from 90 in 2019 to 94 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Sources and how to read this

This page draws on 7 MRV reporting years, an efficiency ranking, 4 of 5 vessel particulars and AIS movements in Norwegian waters. Not found in the sources for this vessel: 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.
