Its purpose is to ensure the integrity and proper operation of pipes, valves, joints, and sections of pipeline installed below sea level. Using video inspection systems, probes, ROV cameras, and technical divers, a thorough assessment is carried out to detect leaks, obstructions, deformations, sedimentation, or displacement along the route.

This type of inspection is essential for industrial facilities, water treatment plants, refineries, and marine terminals, where continuity of flow and environmental safety are priorities. The data obtained is analyzed and recorded in technical reports with photographs and location maps, which serve as the basis for predictive maintenance programs, rehabilitation, or verification of compliance with environmental and operational standards.
