SEAWAYS STAR against its type
Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,266 gross tonnage it is larger than 69% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. The reported port of registry changed: Hong Kong (2022), then Majuro (2025).
Its 9,949 t of CO₂ for 2025 is 1.8 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 309.8 kg CO₂, 24% above the type median of 250.2 kg. It logged 2,756 hours at sea against a median of 2,106 hours for its type that year. 6.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Of the 3 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
