ENERGY SWAN against its type
Built in 2005, it is 6 years older than the median offshore vessel on this register, which was built in 2011 (410 vessels with a known build year). At 4,200 gross tonnage it is larger than 51% 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 22 other vessels here, 4 of them offshore vessels.
Its 4,845 t of CO₂ for 2025 is 20% above the median of 4,049 t among the 390 offshore vessels on this register that reported for 2025. Per nautical mile it emitted 326.2 kg CO₂, close to the type median of 348.3 kg. It logged 3,702 hours at sea against a median of 3,550 hours for its type that year. 5.6% 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.
