Here's what some our our clients have to say

“Sonardyne’s seafloor deformation monitoring technology was a complete game-changer for helping Shell to gain insight into their offshore reservoirs, located in very deep water, where direct access to the seafloor by people is obviously not practical.”

Dr. Paul Hatchell, Shell research geophysicist (retired)

“By applying their decades-long experience in innovative engineering and quality production, Sonardyne has expanded geodetic monitoring of the seabed beyond that of a couple of research groups to a much wider international scientific community…”

Dr. C. David Chadwell, Scripps

“UMS operate in challenging environments and they need to be robust against faltering communications and navigation. Partnering with Sonardyne makes it possible for our autonomous systems to…improve the effectiveness of future underwater missions.”
