Introduction

The RSM-SNR(C) Pipeline Motive Sonar Test System (Blue Whale No.1) is designed for efficient inspection of submerged pipelines, detection wells, and underground cavities. Unlike traditional sonar systems, it integrates powerful propulsion thrusters and a 4K ultra-clear camera, eliminating the need for pulling ropes or cables. The system supports 360° all-directional movement—forward, backward, lateral, ascent, descent, and roll—enabling flexible maneuvering in complex environments. It can accurately identify structural and functional defects (cracks, deformation, branch connections, siltation, obstacles, residual walls, dam footings, etc.), calculate deposition volume, and generate longitudinal silt profiles in real time. With intelligent multi-dimensional 3D visualization, the system greatly improves pipeline inspection efficiency and is especially suited for cities with high groundwater levels. As a complement to CCTV systems, it has become an indispensable tool for water-filled pipeline detection and evaluation.

Applications & Use Cases

Structural surveys of water-filled pipelines (>300 mm) without drainage conditions

Full-pipe inspection and condition assessment

Quantitative analysis of silt deposition to guide dredging work

Detection of water-filled shafts and underground cavities
