Water intake inspection on the Gnioure dam

Ariège, France - 2017

Subsea Tech was entrusted to carry out the water intake inspection on the Gnioure dam in order to identify and localize suspected disorders on the gallery concrete. The entrance of the water intake was found easily in low visibility conditions thanks to a Blueview imaging sonar mounted on a Guardian mini-ROV. Once the entrance was found, the divers just had to follow the ROV umbilical to reach the intake gate and open it so the ROV could enter the tunnel and successfully localize the suspected collapse.

 

Objectives

  • Localize the water intake to guide the divers to the gate
  • Internal inspection of the water intake tunnel to identify and localize the suspected collapse

COVID-19 INFORMATION

Due to the growing coronavirus epidemic, the French government has announced a containment measure for the entire country for a minimum period of 14 days starting March 17, 2020. Therefore, Subsea Tech will partially cease its activity for the duration of the containment. During this period, only commercial and engineering activities (studies in particular) will continue to operate. Production, after-sales service and interventions will be suspended until the containment measures are cancelled.

We would like to take this opportunity to remind you that caution is required and that it is important to respect the basic hygiene instructions, as well as the specific safety instructions put in place by your government.

We thank you for your understanding and look forward to seeing you soon!
