At 4,375 gross tonnage it is larger than 54% of the other 396 offshore vessels with a recorded tonnage. It is one of 5 offshore vessels here under the Liberia flag, 1.2% of the 413 on the register. The same builder is recorded for 23 other vessels here, 15 of them offshore vessels.

Its 7,083 t of CO₂ for 2025 is 1.7 times the median of 4,049 t among the 390 offshore vessels on this register that reported for 2025. Per nautical mile it emitted 957.2 kg CO₂, 2.7 times the type median of 348.3 kg. It logged 4,946 hours at sea against a median of 3,550 hours for its type that year. 7.0% of its 2025 emissions were at berth; the median for offshore vessels was 6.4%.

Sources and how to read this

This page draws on 1 MRV reporting year and 5 of 5 vessel particulars. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, a name history, a licensed photograph, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
