Savante, global leaders in subsea laser measurement and inspection, are proud to announce the completion of the worlds first underwater laser scan of a subsea wellhead.
Savante were contacted directly by a major oil and gas operator after a general visual inspection (GVI) campaign detected an area of suspected damage on a wellhead sealing face. Video cameras placed within the well at that time using remotely-operated vehicles (ROVS) were unable to confirm the extent of the damage. Significantly, a well re-entry had been scheduled with a semi-submersible rig already en-route.
Dr. Grant Thomson, director of Savante was exceptionally pleased with the project outcome. “Our task was to confirm the extent of any sealing face damage found within the wellhead. We deployed a subsea laser scanner from the UK immediately and were standing-by in-field with our system integrated aboard an “ROV of opportunity” within 24 hours. We entered the wellhead and completed a 3D laser scan of the damaged area in 12 seconds, immediately providing our client with 3D cross section measurements through the damage to microscopic accuracy. This was supported with a close-up confirmation video provided by our onboard camera.”
Provided with an immediate 3D laser-scanned model of the damaged area, the client was able to focus on targeting a specific remedial sealing solution, well in advance of the arrival of the semi-sub.
