Subsea Inspection & Monitoring: Sonar, Cameras, Leak Detection
Overview
Built Around Your Application
Maintaining the integrity of offshore infrastructure requires technologies that can see clearly, detect anomalies early, and deliver reliable data in challenging subsea environments. C.A. Richards represents manufacturers whose inspection and monitoring systems are trusted by operators in the offshore and subsea industry — from acoustic leak detection and multibeam sonar to high-definition underwater cameras and radiometric inspection tools.

Learn MoreCommon Engineering Questions
Answers to the technical questions we hear most often from engineers and project teams.
How can offshore operators detect subsea leaks acoustically?
Acoustic leak detection uses the sound generated by fluid or gas escaping through a defect in a pipeline, valve, or fitting to identify and locate the leak. Tracerco and similar technologies use passive acoustic sensors or active measurement techniques to detect anomalies in subsea pipelines and infrastructure. The advantage over visual inspection is that acoustic methods can detect leaks that are not visible to cameras, including internal leaks and leaks obscured by marine growth or sediment. C.A. Richards represents Tracerco for pipeline inspection and leak detection applications.
What imaging sonar is used for subsea pipeline inspection?
Imaging sonar is used for pipeline inspection in conditions where optical cameras are limited by turbidity, low light, or the need to inspect large areas quickly. Sound Metrics DIDSON and ARIS imaging sonars produce high-resolution acoustic images that can reveal pipeline condition, marine growth, free spans, and structural anomalies. Kongsberg Discovery multibeam sonar systems are used for pipeline route surveys and seabed mapping around subsea infrastructure. The choice of sonar depends on the inspection objective, pipeline diameter, water depth, and required resolution.
What equipment is used for underwater acoustic monitoring?
Underwater acoustic monitoring uses hydrophones to detect, record, and analyze sound in the ocean. Ocean Sonics icListen smart hydrophones are self-contained digital hydrophones used for passive acoustic monitoring of marine mammals, ambient noise, structural acoustics, and subsea machinery. Applications include environmental compliance monitoring, leak detection, structural health monitoring, and ocean science research. C.A. Richards represents Ocean Sonics for acoustic monitoring applications across offshore energy, defense, and ocean science markets.
What is radiometric inspection for subsea pipelines?
Radiometric inspection uses gamma-ray or X-ray sources to measure the density and composition of materials inside a pipeline without requiring physical access to the interior. Tracerco pipeline inspection tools can detect wax, scale, hydrate, and corrosion buildup inside subsea pipelines from the outside, providing operators with information about internal condition that cannot be obtained by visual inspection alone. This technique is particularly valuable for flow assurance monitoring on production pipelines where internal access is not practical.
