Use case

Structural assessment of the Jean Réveille and d’Estienne d’Orves pier

Saint-Tropez, France - 2016

Subsea Tech carried out the 3D underwater modeling of the pier over a 500m distance, using the CAT-Surveyor USV. The results were correlated with the surface observations to point out the disorders affecting the pier and provide the client with a complete diagnosis. 3D sonar models were completed by mini-ROV video inspections to characterize precisely the disorders.

Objectives

• 3D modeling of the pier using a multibeam echosounder
• Visual inspection of the pier
• 3D modeling of particular disorders
