The granted patent US12073950B2 outlines a sophisticated underwater repairing system designed for applying adhesive to repair locations within containers. Central to this system is a movable and remotely controlled repairing robot, which is modular in construction. The robot features a central repairing module that can connect to various additional modules, including an adhesive applying module and a cleaning module. The adhesive applying module is specifically designed to dispense adhesive at the repair site, utilizing an appliance brush for application. The system also includes driving interfaces that allow the robot to navigate underwater, ensuring effective mobility. Furthermore, the repairing module can be equipped with additional functionalities such as a location finding module, a leakage determination module, and a camera module to enhance operational efficiency.

The patent also describes a method for utilizing this repairing system underwater. This method involves maneuvering the robot to the designated repair location and applying adhesive using the appliance brush. Prior to adhesive application, the method includes a cleaning step to prepare the surface for effective bonding. Additionally, the localization of the repair site can be achieved through techniques such as Alternating Current Field Measurement (ACFM) or by assessing leakage levels. This comprehensive approach not only facilitates the repair process but also ensures that the adhesive is applied accurately and effectively in challenging underwater environments.
