THOR B against its type
Built in 2006, it is 5 years older than the median offshore vessel on this register, which was built in 2011 (410 vessels with a known build year). At 675 gross tonnage it is smaller than 95% of the other 396 offshore vessels with a recorded tonnage. It is one of 8 offshore vessels here under the Portugal flag, 1.9% of the 413 on the register.
Its 1,078 t of CO₂ for 2025 is 73% below the median of 4,049 t among the 390 offshore vessels on this register that reported for 2025. Per nautical mile it emitted 75.6 kg CO₂, 78% below the type median of 348.3 kg. It logged 1,862 hours at sea against a median of 3,550 hours for its type that year. 25.2% 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, 6 reported a lower CO₂ per nautical mile than this vessel.
