First HAIN subsea system installed on DOF ROTVEquipment & Technology // May 21, 2010
DOF Subsea Norway has installed the first Kongsberg Maritime Hydroacoustic Aided Inertial Navigation (HAIN) subsea system on a MacArtney Focus 2 ROTV (Remotely Operated Towed Vehicle).
The system was installed in Stavanger on the vessel Geosund in preparation for pipeline inspection work for the Danish sector of Maersk. Geosund already has a HAIN subsea installed on its Remotely Operated Vehicle (ROV). This is integrated into the survey Eiva Navipak system along with the Edgetech sidescan on the ROTV.
