Geophysical & Geotechnical Site Surveys

We have a proven track record of innovation in Survey Management Models for our clients. Our goal is not just to provide capacity but to enhance processes and deliver more adaptable and commercially viable solutions.

Since 2017, we have been offering geophysical and geotechnical Survey Management services. From 2018 to 2023, we were the largest provider of these services on the Norwegian Continental Shelf.

Recognising the increasing demand for additional capacity, we are excited to introduce a new and flexible solution designed to meet a substantial portion of the market’s need for geotechnical surveys. Introducing the M/V Ross Eagle, a dynamically positioned geotechnical investigation vessel.
