Tunnel Wall Imaging System (TWIS)
The Tunnel Wall Imaging System (TWIS) operates similarly to the Driver View Imaging System (DVIS), but is directed to produce detailed images of the tunnel walls. Just like the DVIS, it has the unique advantage that it is synchronized with all other inspection systems on the vehicle. This allows it to be a useful source of imagery to provide context to any defective condition identified on other systems, such as tunnel clearance encroachments detected by the Clearance Measurement System (CMS). Additionally, similar to the DVIS, the TWIS is offered with both infrared and visual light options.
Tunnel Water Leaks
When ENSCO’s TWIS is paired with our Thermal Imaging System (THIS), the combination has the unique capability to find locations of tunnel water leaks. The thermal imaging provides a clear indication of where water is present and the detailed images from the TWIS give insight of the specific issue.
