SHANNON STAR against its type
Built in 2010, it is the same age as the median chemical tanker on this register (build year 2010, 1,951 vessels with a known build year). At 8,986 gross tonnage it is smaller than 83% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. The returns for 2018–2025 all give Valletta as port of registry.
Its 6,482 t of CO₂ for 2025 is 17% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 231.7 kg CO₂, close to the type median of 250.2 kg. It logged 2,845 hours at sea against a median of 2,109 hours for its type that year. 12.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2019 (9,186 t) and the lowest 2025 (6,482 t). Its efficiency percentile within the type went from 93 in 2018 to 97 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.
