DBMAS® Dry Bulk Management System

The loading and discharging procedures of the vessel are executed with complete automation, reliability, and safety in mind. Every aspect of filling and emptying the cargo holds is meticulously overseen by a PLC (Programmable Logic Controller). This specialized industrial-grade computer is purposefully engineered for exceptional performance, even in the demanding onboard environment of cargo vessels. 


Programmable Logic Controller

The PLC is securely housed within the deckhouse, ensconced within a dedicated control cabinet. To oversee and manage the vessel’s loading and unloading operations, a monitor has been seamlessly integrated into the control cabinet. This high-resolution display showcases an intuitive program with a user-friendly graphic interface, providing clear visual indicators of valve positions and facilitating efficient supervision and control.


Advantages of our DBMAS®


Because our computer program operates all remote-controlled valves, there is no risk of accidental opening of pressurized lines, ensuring safety and precision. 

Easy to operate

Low skill is required to operate the DBMAS® while still maintaining full discharge capacity and no possibility of human errors.

No blockage in cement line

As the air supply is regulated by the DBMAS®, there is no danger of blockage of the cement line. This is an advantage for operators on a tight time schedule of today’s charters.

Savings on installation for shipyard

The wiring between the E.R. main electrical cabinet and the wheelhouse control screen is limited to one wire instead of 200+ wires from the E.R. to wheelhouse. There are no Victaulic type fast couplings required on the cement line.

Small wheelhouse panel

The Wheelhouse panel is streamlined, featuring only a compact interface comprising an on/off switch, an emergency stop (EM) button, and a display. This minimalist design allows designers to conserve valuable installation space for additional onboard equipment.

Discharging program

The specially crafted discharge program offers substantial advantages. The DBMAS® discharge program empowers users to configure the desired discharge pressure. In this process, the discharging sequence is automatically initiated by DBMAS®, which includes verifying proper operation and the availability of cooling water supply for the compressors. Subsequently, this process pressurizes the tanks. Once the tanks reach the desired pressure, the discharge valve is automatically opened, ensuring the discharging rate is maintained at its maximum capacity, thanks to the automatic regulation of purge air. 


Loading program

The DBMAS® system features a dedicated loading program. The operator has the flexibility to input the choice of the specific hold and the side from which loading will occur. The DBMAS® system responds by automatically opening the relevant valves accordingly. Throughout the loading process, it provides clear visibility regarding which hold is currently receiving cargo. Moreover, when the initial hold is filled to capacity, the program seamlessly transitions to the next designated hold. To alert the operator upon the completion of the filling process, an audible signal is triggered.


The DBMAS® system offers the optional Connectivity Module, providing the capability for remote assistance and servicing of the entire equipment directly from our office via the Internet. This feature can significantly save ship owners both time and money that might otherwise be lost in the event of a vessel breakdown. By establishing a connection with the vessel’s DBMAS®, we can swiftly address any onboard failures.

Communication with the vessel can be established through either a GSM modem (accessible within the GSM range of most ports) or a SATCOM modem (providing worldwide access). This connectivity enables us to deliver prompt and effective online service and assistance. Extensive diagnostics and troubleshooting can be conducted without the necessity of physically traveling to the vessel, thereby mitigating the associated time and financial losses.


It is possible to incorporate the control system at the receiving end of the convey line with the receiving computer system. By connecting with standard cable connection, we can integrate into any system of an import terminal where the vessel is discharging. The terminal can then stop the discharging process in case all of the silos are full or in case a malfunction of some critical valves occurs. 

Clean Up

During the moment that cement is on a very low level in the hold and only limited cement is sucked out of the ship (during clean up) the power (fuel) consumption will be reduced. Due to this optimizing program, the fuel consumption of the equipment is related to the amount of material handled and as such, no fuel is wasted.
