Functioning [Video Lesson]

The anti-healing system or anti-rolling tank system automatically detects the heeling angle of the ship and compensates for the same. This allows the vessels to have continuous loading and unloading cargo operations without stopping in between for list correction.


This saves a considerable amount of time on the port. In this system, ballast tanks are internally connected to each other by means of pipelines, automatic valves, and control systems.


When the ship heels to any of the sides, the heeling sensor sends the signal for a change of ship angle with respect to the ship’s upright position to the master control panel.


This change in heeling angle is compensated by methods of auto-transferring the water from the heeled side to the other side of the ship, making the vessel upright.
