In certain vessel types, Anti-Heeling is a compulsory tool and asset. NORR SYSTEMS is able to deliver the complete solution to these vessel types eg. RoRo, Containers, Barges etc that includes both Tank Management and Anti-Heeling integrated into a

single solution. Not only is the solution cost effective but also highly reliable.

The Anti-Heeling control system is used to detect the heeling angle of the vessel and to rebalance the ship automaticly by pumping ballast water from starboard to port or vice versa. The system can operate with reversible or non reversible pumps, using Remote Controlled Valves to ballast water flow.

The complete system includes:

1. Anti-Heeling Control Panel
2. Pump starter Panel
3. Heeling Pump
4. Heeling Valves
5. Level Transmitters
6. Level Switches

The Anti-Heeling system AH2000 and AH2000i can work in conjunction with the stability control system and the valve remote control system for bilge and ballast valves control, the precision heeling sensor, mounted athwart to the ship's direction and supplies the heeling angle to the master PLC

More complex Anti-Heeling system make use of 4 anti-heeling tanks and inclinometers with 4 axis (port, starboard, forward and aft)

Such system are employed on some vessels which require the vessel to anti-heel itself at 4 axis during operation.

The master CPU is housed in a flush mounting. The fron panel of the anti-heeling includes selected switch for mode selection and lamp test, integrated in a mimic panel.

The ballast pump starts only if it get the signal that the respective valves are opened. This valves will be controlled by means of master PLC.

When pump starter panel in operation mode, signal "SYSTEM READY" will send to master PLC, anti-heeling control system is enabled.
