WIND ENERGY 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 11,730 gross tonnage it is larger than 85% 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 660 other vessels here, 2 of them offshore vessels.

Its 6,215 t of CO₂ for 2025 is 1.5 times the median of 4,049 t among the 390 offshore vessels on this register that reported for 2025. Per nautical mile it emitted 2,668.8 kg CO₂, 7.7 times the type median of 348.3 kg. It logged 670 hours at sea against a median of 3,550 hours for its type that year. 8.7% of its 2025 emissions were at berth; the median for offshore vessels was 6.4%. The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.
