Catamaran and AUV Complete Joint Survey

Norwegian and Canadian partners have completed geophysical area survey in Norway using an autonomous underwater vehicle (AUV) and small catamaran concept.In September 2018 DOF Subsea Norway AS was awarded a contract for The Norwegian Public Roads Administration, Statens Vegvesen (SVV), to perform geophysical mapping of a 5km2 area in Bjørnafjord in Norway. The project was executed using the Hugin AUV Chercheur manufactured by Kongsberg Maritime and owned and operated by Canadian company Ocean Floor Geophysics Inc. (OFG) in combination with the small survey catamaran GeoCat owned by DOF Subsea
