At 850 gross tonnage it is smaller than 95% of the other 396 offshore vessels with a recorded tonnage. It is the only offshore vessel on this register under the Sweden flag.
Its 625 t of CO₂ for 2025 is 85% below the median of 4,049 t among the 390 offshore vessels on this register that reported for 2025. Per nautical mile it emitted 71.8 kg CO₂, 79% below the type median of 348.3 kg. It logged 1,800 hours at sea against a median of 3,550 hours for its type that year. 15.9% of its 2025 emissions were at berth; the median for offshore vessels was 6.4%. Of the 8 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.
