USV WITH MULTIBEAM ECHOSOUNDER FOR SHANGHAI BRIDGE SURVEY
The Donghai Bridge, located in Shanghai, China, is a key component of the Shanghai International Shipping Center’s deepwater port infrastructure. Conducting underwater surveys of the bridge piers’ conditions for maintenance purposes is an operational challenge. The bottom of the bridge piers is immersed in water and can be eroded by the action of sand and gravel. Hydrodynamic scour caused by rapid water flow can create scour holes and compromise the integrity of the structure. The solution selected for the Donghai Bridge survey project comprises an unmanned survey vessel, the APACHE 6 of CHCNAV, carrying a NORBIT iWBMS STX multibeam echosounder.
