Length and difficult accessibility have traditionally made pipelines laborious and expensive to inspect. Recognising underwater damage caused by factors such as erosion has been challenging.

With VRT’s sonar technology for underwater pipeline surveys we can inspect pipelines from one end to the other, faster, safer and infinitely more accurately than any other inspection method.

Our easy-to-comprehend images display underwater structures with unrivalled accuracy finding previously inaccessible defects. The entire sonar imaging process is carried out from a boat using the latest 3D technology. This means less need for divers or other underwater equipment, resulting in the fastest, most conclusive inspections – cost efficiently.
