What is Anti Heeling Control System (AHCS)?

The Anti Heeling Control system is used to detect the healing angle of the vessel and to rebalance the ship automatically 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 derect the ballast water flow. The complete system inclide the master and optional the slave electronic unit, the mounting plate with heeling sensor, the pump starter panel, the pump and two level switches for low tank level. The Anti healing system can work in conjunction with the stability control system and the valve remote control system for bilge and ballast valve congtrol. The precision heeling sensor which is installed on the mounting plate will be placed mid-ship and supplies the heeling angle to the master electronic unit. The master electronic unit with CPU is housed in a flush mounting box. The front panel of the electronic unit includes push buttons for mode selectrion and lamp test, integrated in a mimic panel. The supply of the master electronic unit is made via the mounting plate. The master electronic unit can supply serial data to a optional installed slave electronic unit (e.g. WH Console). Both units have the same control push buttons, indication lamps and a bar graph for heeling angle indication. In general, master and slave can used without any priority by the operator. During pressong of any button at one of the electronics units, the corresponding unit will blocked for a short time interval. The output signal of the master or the slave unit are controlling the heeling valves and the heeling pump via the pump starter panel. http://www.vinamaso.net/marine-engineering/automation-control/what-is-anti-heeling-control-system-ahcs.html < Prev   Next >
