AI Technical Summary

Technical Problem

Existing traditional fenders are prone to displacement and cannot meet the current safety standards for refueling operations, especially when the relative motion between the two vessels is large, increasing the risk of collision.

Method used

The magnetic inflatable fender device for ships uses magnetic components to adhere to the hull. Combined with an elastic shell and an independent inflation chamber design, it achieves stable adhesion and real-time monitoring through controllers and sensors, ensuring the device remains stable in complex sea conditions.

Benefits of technology

It improves the stability and safety of the bumper device, avoids the risk of collision caused by the bumper slipping, enhances the safety and convenience of the filling operation, extends the service life of the device, and promptly alerts the operator through sensors.
