THUN VENERN against its type

Built in 2018, it is 8 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 12,770 gross tonnage it is smaller than 66% 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 same builder is recorded for 40 other vessels here, 32 of them chemical tankers. The returns for 2018–2025 all give Lidköping as port of registry.

Its 9,506 t of CO₂ for 2025 is 1.7 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 148.6 kg CO₂, 41% below the type median of 250.2 kg. It logged 6,082 hours at sea against a median of 2,109 hours for its type that year. 8.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2025 (9,506 t) and the lowest 2018 (2,377 t). Its efficiency percentile within the type went from 49 in 2018 to 65 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.
