A regional council client required inspection and condition assessment of a submerged pipeline asset. In response, our team deployed a ROV integrated with multi-beam sonar imaging and a pipeline profiling system to capture structural data. This enabled accurate assessment of the pipeline’s condition without relying on traditional visual inspection methods, supporting informed maintenance and asset management decisions.

The submerged pipeline presented a complex inspection, with extremely low visibility, rendering traditional camera-based inspection methods ineffective. The challenge was to obtain reliable structural data from within the pipeline, requiring a solution capable of generating a clear representation of the asset’s condition without clear visual imaging in a confined underwater space.

Our team deployed an ROV fitted with high-definition front and rear-facing cameras integrated with multi-beam sonar imaging and a pipeline profiling system, to conduct a full internal survey of the asset. The ROV was navigated through the pipeline as the profiler captured continuous acoustic data, which was processed in real time to generate a detailed internal profile. This enabled accurate assessment of structural condition and anomalies without reliance on visual inspection or intrusive methods.

Our operation enabled the client to obtain detailed structural data from their submerged pipeline asset. Traditional visual and personnel-based inspection methods were ineffective in this environment and presented increased safety risks. Following data acquisition, our team processed the pipeline profiler outputs to generate a comprehensive representation of the pipeline’s internal condition, producing a complete structural map of the inspected section.
