Port visualization survey

This survey is conducted to determine the condition of the vertical plane of the dock and confirm the degree of erosion or subsidence of the structure. In the investigation, the staff used a lightweight handheld frame to hold the sonar head at a fixed distance, keeping it perpendicular to the vertical plane. The system does not use surface support boats and chooses to settle and lower from the dock.

Sonar scanning is performed at intervals of 10 meters. In order to achieve the puzzle, the source of the sonar will be deleted, and Adobe Photoshop will be used at the same time ® Replace with adjacent scanned coverage areas and add text using Microsoft software.
