Remote flooded member detection

摘要

Utilizing a sonar system to determine if a structural member of an underwater support structure that is supposed to be filled with air is instead flooded with water. The determination that a supposedly air filled structural member is instead flooded with water provides an indication that the structural member is cracked or damaged, making it easier to find damaged members and effect suitable repair. The sonar system is located a distance from the structural member so that it is spaced from the structural member.
