Tunnels and pipelines are hidden from sight, have limited access and can be several kilometres long. De-watering tunnels and pipelines for walk-through inspection is not always possible and when attempted, can be dangerous and costly. Leaving the tunnel or pipeline in a watered state eliminates the time required to safely dewater, water back up and eliminates water waste.
In some cases, the inspection of the tunnel or pipeline cannot be accomplished as some facilities were not built with the intent of ever isolating or dewatering them. For these assets, the use of remote systems is an enabling technology that provides an inspection solution where there previously was none. Using submersible remotely operated vehicles (ROVs) eliminates the risks associated with confined space entry by personnel.
ASI understands that time is of the essence when such assets are taken out of service and commits sufficient resources to provide 24-hour continuous operations for as long as the client requires. ROVs are controlled from the surface and all of the data from the vehicle sensors are displayed in real-time and recorded for future review. This unique capability places ASI as the world leader for long tunnel inspection work. For over 30 years ASI Group has solved the world’s toughest underwater challenges. ASI Marine provides clients with experienced personnel, tailored solutions, accurate data and comprehensive reports needed to make critical, timely and cost effective decisions regarding underwater infrastructure remediation, maintenance and repair. ASI Group’s tunnel experience optimizes the combination of equipment and inspection protocols to satisfy project goals efficiently and with consistent quality.
