Comparison of New Advances in Underwater Bridge Inspection Technology

摘要

Inspection of bridge elements below-water and the channel bottom surrounding these elements is essential for ensuring public safety and promoting long-term serviceability of bridges over waterways. Although underwater technologies have been used to supplement underwater bridge inspection by divers for many years, recent advancements, including newly developed equipment using acoustic principals most often employed in the offshore oil and gas industry, have resulted in new and improved underwater inspection, support, and documentation methods.
