Fields of gold

The Expro Group has developed an ultrasonic processor which causes less damage to the seabed and local sea-life. The processor is also quicker than the conventional method of grinding. The processor has been tested by Agip (UK) and the subsea template does not become clogged with cutting debris. This reduces the overall costs as there is no clean-up required afterwards. ABB Vetco Gray modified a GLL tree so it could be used at record depths in Offshore Brazil. AEA Sonamatic developed Non-Destructive Testing which uses ultrasound to inspect subsea pipelines.
