Side Scan Sonar Survey

Side Scan Sonar survey is an advanced acoustic imaging technique that produces high-resolution, two-dimensional images of the seafloor. Unlike bathymetric systems that measure depth, side scan sonar creates detailed "acoustic pictures" of the seabed, revealing objects, debris, bottom texture, and geological features. This technology is essential for object detection, pipeline inspection, and seabed characterization.

Technology Overview
• Dual Frequency Operation – Combines low and high frequencies for wide coverage and high detail
• Wide Swath Coverage – Covers large areas efficiently, up to several hundred meters per side
• High-Resolution Imaging – Detects small objects and fine seabed details
• Real-Time Data Display – Immediate visualization of seabed conditions
• Towfish or Hull-Mounted – Flexible deployment based on project requirements

• Integrated Positioning – Combined with GNSS for accurate object location

Key Applications
• Pipeline & Cable Inspection – Detects exposed, buried, or damaged subsea infrastructure
• Shipwreck & Obstruction Detection – Identifies hazards to navigation and construction
• Seabed Characterization – Maps bottom type (sand, rock, mud, gravel) for engineering studies
• Unexploded Ordnance (UXO) Detection – Locates and identifies potential hazards
• Archaeological Surveys – Discovers and documents underwater cultural heritage
• Dredging Support – Identifies hard bottom areas and monitors dredging progress
• Environmental Studies – Maps benthic habitats and marine ecosystems
• Search & Recovery Operations – Locates lost objects and debris
