Simultaneous Cable-Less Video Inspection of Pipelines with Integrated Leak Detection

This paper examines the benefits and applications of performing a cable-less multi-sensor measurement survey. Video recordings prove that the battery powered and ballasted Pipe-Inspector remains neutrally buoyant and remains stable while centrally positioned inside the pipe, eliminating spiralling or bouncing data collection inaccuracies. Advancements enabling pinpointing leaks from within the pipe to a distance and clock position are enabling system owners to better understand their pipe’s integrity and risks. CCTV adds a level of understanding to better manage the system’s health, when correlated to pressure and leak survey findings. The cable-less function enables very long lengths of pipe to be surveyed with no impact to surface urban or environmental conditions. This technology advancement is proving financially beneficial to system owners concerned with limited budgets. First line triage of a pipe’s condition is now capable of simultaneously providing many valuable sources of information to better assist engineering decisions for condition assessments.
