ESVAGT CASSIOPEIA against its type
Built in 2007, it is 4 years older than the median offshore vessel on this register, which was built in 2011 (410 vessels with a known build year). At 963 gross tonnage it is smaller than 90% of the other 396 offshore vessels with a recorded tonnage. It is one of 62 offshore vessels here under the Denmark flag, 15.0% of the 413 on the register. The same builder is recorded for 8 other vessels here, all of them offshore vessels.
Its 1,519 t of CO₂ for 2025 is 62% below the median of 4,049 t among the 390 offshore vessels on this register that reported for 2025. Per nautical mile it emitted 189.9 kg CO₂, 45% below the type median of 348.3 kg. It logged 7,928 hours at sea against a median of 3,550 hours for its type that year. 2.6% of its 2025 emissions were at berth; the median for offshore vessels was 6.4%. Of the 4 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.
