Veolia hydrographic surveys are performed with the most advanced equipment available, including:

• Multi-beam Sonar
• Shallow Water Array Sonar: The Veolia Array Surveyor is a pontoon-style vessel custom designed to for shallow water survey (less then 2 feet of water).
• Dual-frequency 150/600 Khz Tow-Fish side-scan sonar
• High-resolution Edgetech sub-bottom sonar
• Imagenex 881 sector-scan sonar: The sector-scan sonar is deployed for obstacle avoidance, target location and interior pipeline scans.
• Accurate positioning systems: Veolia teams use commercial-grade DGPS with submeter accuracy as a standard for all survey work and RTK systems capable of reporting positions within +/- 2-3 cm when great accuracy and reliable vertical reference is critical. Total-station survey is used for limited applications.
• Four ocean-going support vessels providing dive support, remotely operated underwater vehicle (ROV) support and multi-purpose support for marine projects—the Kingfisher, the Swordfish, the Viking Poseidon and the Normand Pacific.
• Triton work-class ROVs
• Inspection-class ROVs
