Norwegian joint venture USV has ordered its first unmanned ship for offshore wind farm work.

The company, formed in June last year by Solstad Offshore, Ostensjo Rederi and DeepOcean, has picked Astilleros Gondan in Spain to build the unmanned surface vessel.

It is estimated that the ship can cut CO2 output by more than 90% compared with a conventional offshore vessel when conducting subsea inspection, maintenance and repair operations, as well as reducing operating expenses.
