Per nautical mile it emitted 1,284.1 kg CO₂, 3.7 times the type median of 348.3 kg. It logged 1,082 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 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Sources and how to read this

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