ABSTRACT
Aquatic Sciences Inc. began internal ROV inspections of flooded pipelines and tunnels in the early 1990s. Techniques and methods have improved beyond the scope of simple video camera imaging to include sonar, doppler, pressure differential sensors and robotic interface with underwater fairleads. Remote distance capabilities of 10 km are now a proven technique.
This paper will assess remote inspection technologies based on actual project results. Different ROV systems will be examined according to their application to various pipeline and tunnel diameters and lengths and to the respective inspection requirements involved.
