TTSM has the experience to carry out hydrographic surveys to inspect seafloor conditions whether in nearshore locations or in the open ocean, as well as inland waters (rivers, lakes etc.). These surveys are a response to several needs in terms of engineering and environment.

Multiple survey tools are available:

• Single beam echosounder
  
• High resolution multibeam echosounder
  
• Side scan sonar survey   

High resolution charts, imagery and video graphics can be generated for different purposes:

• Site assessments
• Underwater inspections/ design of marine structures and subsea installation
• Submarine cables and pipeline installation    
• Coastal erosion  
• Volume calculation in dredging operations
  
• Morphological studies
  
• Navigational safety
  
• Search, rescue and recovery operations
