TERN ISLAND against its type
Built in 2021, it is 11 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,432 gross tonnage it is smaller than 78% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 93 chemical tankers here under the Denmark flag, 4.0% of the 2,344 on the register. The returns for 2022–2025 all give Skagen as port of registry.
Its 9,010 t of CO₂ for 2025 is 1.6 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 149.2 kg CO₂, 40% below the type median of 250.2 kg. It logged 5,192 hours at sea against a median of 2,109 hours for its type that year. 10.9% 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 (10,076 t) and the lowest 2023 (8,062 t). Its efficiency percentile within the type went from 74 in 2022 to 70 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
