Norwegian offshore operator Reach Subsea has ordered the first two in a series of “game-changing” unmanned survey ships.

Domestic group Kongsberg Maritime will build the vessels as part of the Reach Remote project.

The unmanned offshore surface vessels (USVs) will serve as mobile power banks, data centres and communication modules for underwater remote-operated vessels (ROVs), Reach said.

Both the USVs and ROVs will be operated from an onshore control centre.
