2-D & 3-D Underwater Imaging

Underwater inspection of bridge structures is essential for maintaining long-term structural safety and serviceability. Although hands-on visual and/or tactile inspection by a qualified engineer-diver is the only way to truly determine structural condition with certainty, advancements in underwater imaging technology assist the engineer-diver in this endeavor.

2-D and 3-D underwater acoustic imaging of underwater areas, structures, and objects shows what the divers observed or felt, regardless of water clarity. Acoustic imaging allows Collins to perform quantitative measurements of below water structure configurations, structural deficiencies, and scour depressions. Using this technology increases the efficiency and safety of the diving engineer by identifying potential structural deficiencies and hazards prior to entering the water. It can also be used to document complex features in emergency situations when the use of divers is deemed unsafe.
