At 48,949 gross tonnage it is larger than 98% of the other 396 offshore vessels with a recorded tonnage. It is one of 34 offshore vessels here under the Bahamas flag, 8.2% of the 413 on the register. No other vessel on this register is recorded with the same builder.
Its 35,967 t of CO₂ for 2025 is 8.9 times the median of 4,049 t among the 390 offshore vessels on this register that reported for 2025. Per nautical mile it emitted 2,911.9 kg CO₂, 8.4 times the type median of 348.3 kg. It logged 5,321 hours at sea against a median of 3,550 hours for its type that year. 8.6% of its 2025 emissions were at berth; the median for offshore vessels was 6.4%. Of the 6 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.
