AURORA SANDEFJORD against its type
Built in 2011, it is the same age as the median offshore vessel on this register (build year 2011, 410 vessels with a known build year). At 8,360 gross tonnage it is larger than 80% of the other 396 offshore vessels with a recorded tonnage. It is one of 70 offshore vessels here under the Norway flag, 16.9% of the 413 on the register. The same builder is recorded for 13 other vessels here, 10 of them offshore vessels. K Line Offshore AS is linked to 3 vessels on this register.
Its 7,145 t of CO₂ for 2025 is 1.8 times the median of 4,049 t among the 390 offshore vessels on this register that reported for 2025. Per nautical mile it emitted 597.0 kg CO₂, 1.7 times the type median of 348.3 kg. It logged 2,834 hours at sea against a median of 3,550 hours for its type that year. 4.2% of its 2025 emissions were at berth; the median for offshore vessels was 6.4%. Of the 6 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.
