Offshore installations

Argeo has a long track record of advanced geo-engineering services for the offshore and infrastructure industry having completed some of Norway’s most complex construction projects in modern times using a combination of advanced data acquisition in combination with high-end 3D geomodelling solutions

Whether our customers are involved in infrastructure construction or offshore installation, the likelihood of Argeo having experience in this field of expertise is high. Using AUV’s for complex bridge construction or Aquaculture project to complete geo-steering based on digital 3D models reduces both project cost and risk.
