DBMAS® [12" touch screen] controls the loading & discharging of all the dry bulk tanks. It controls all the valves, compressors, dryers of the Van Aalst discharge system. The centre of DBMAS® is a PLC (Programmable Logic Controller). This industrial type of computers is specially designed for the use onboard support vessels. The PLC of the DBMAS® is installed inside an electrical cabinet in the engine room. To control DBMAS® a touch screen display is installed in the wheelhouse panel (flush mounted type). From this touch screen all functions can be controlled and monitored. There is a possibility to extend the number of touch screens.
On the special designed discharge program the advantages are enormous. The DBMAS® discharge program makes it possible to set the required discharge pressure and the discharging sequence. DBMAS® will automatically start the compressors and dryers, after checking with main switchboard (heavy load enquiry function) also for sufficient cooling water supply. After this the bulk tanks will be emptied / discharged onto the offshore platform. Once the discharging is started, the discharge rate will be kept to a maximum.
The DBMAS® is equipped with a special loading program. The operator can identify from which bulk tanks from which side will be loaded. The DBMAS® will open the relevant valves. During the loading it is visible which is loaded and which tank needs to be loaded. If the 1st tank is full, the program will automatically switch over to the next tank. The operator will be notified by an acoustic signal if the filling procedure is completed.
