Marshal Systems’ Vessel Monitoring System (VMS) is designed in accordance to marine / offshore standard codes and certified by international class regulatory bodies, to monitor various system alarms and alerts critical conditions of the processes throughout the facilities. We design the VMS as a distributed I/O system which is scalable to meet end-users / operational crew’s demand at any time.

The design philosophy is to achieve high reliability, safety and cost efficiency. Redundant CPU and Servers allow critical applications to continue operating even if there is a single component failure, hence it prevent the risk of downtime. Remote I/O cabinets are connected to the main cabinet via redundant communication (Profibus / Profinet / MODBUS / Controlnet).

Marshal Systems has developed AFMS whose core concept is to monitor and pre-alert the operator about the connected system’s abnormality via alarms to prevent the system failure.

The occurred alarms will be logged in a built-in data logger as a history log; it will support maintenance crews for fault analysis and troubleshooting to minimize down time for a smooth operation.

Marshal Systems supplies Alarm Monitoring systems to notify the operators on alarm and status information of the machinery, in order to maintain safe and efficient operation of the onshore and offshore facilities. We customise the systems according to operation needs and ensure that the system is user–friendly too.

Our user-friendly HMI provides the alarms and other information as text or graphical representation on local and remote operator’s station. Alarms from various systems are received by the Redundant CPU PLC, which will process the alarms and log the events. These alarm events can be printed out by alarm printer.

Marshal systems delivers Tank Gauging system to end-users for their monitoring of various types of tank , in term of tank volume / mass / level, such as ballast, water, draft, bilge, fuel oil, cement and solid matters … in the offshore and onshore facilities. We use different technologies with Electro-Pneumatics transmitters, Contact and Contactless sensors, and field instruments like Radar, Ultrasonic, float switches … etc.

Various inputs, such as bubbling point & signal from the field transmitters and sensors, are received by the PLC modules in the control panel. These inputs are processed and converted as HMI graphical display on the touch screen monitor.

Our system configures various alarm levels and it can also interface to others’ monitoring systems via industrial communication protocols such as HART, Modbus RTU, and Ethernet.

Marshal Systems supplies Control System for HVAC system to provide integration between HVAC and Fire & Gas detection systems, in order to activate fire dampers and relay control logics of the ventilation field equipment in the onshore and offshore industries. Our system design meets specification and requirement from customers, clients and class regulatory bodies.

Marshal systems provides Remote Valve control system (RVCS) for a comprehensive control and motoring all types of remote operated valves, such as Hydraulic, Pneumatic and Electric motorised types, on offshore and marine vessels. Our system compliance to major marine class regulation bodies such as ABS, DNV-GL, BV, Lloyds Register … etc.

The Valves Remote Control is reliable for the management of ballast valves to fill and dump ballast tanks. The system consists of a PLC control cabinet, remote I/O cabinet and a Centralised Solenoid Valve Cabinet. The HMI screen will be customised to meet operators requirement.

Marshal Systems provides Water-tight door and hatch monitoring systems to monitor the status of the water-tight doors and hatch accesses, as a parts of vessel watertight integrity in the marine vessels and floating offshore installations. Our system will be design to compliance to major marine class regulation bodies such as ABS, DNV-GL, BV, Lloyds Register … etc.

The system consists of Sensors like proximity / limit switches, local indication lights, HMI / Mimic display panels and main PLC control cabinet. The system provides open / close status of the watertight doors and Hatch accesses. The system can be interface to other alarm monitoring system or vessel monitoring system via various communication protocol such as Modbus, Profinet, Ethernet.

Marshal Systems provides Bulk Transfer Control system of the Bulk Mud and Cements (such as Barite, Bentonite & Cement) for offshore supply vessel (OSV) and drilling rigs. Our system will be tailor-made to meet operators’ requirement for the safe and hazardous areas.

The system uses PLC and guided microwave level sensor to control the valves and monitor the level of the bulk tanks during bulk transfer process respectively. The bulk transfer process can be displayed in P&ID format using HMI screen or mimic display panel.

Marshal Systems supplies customised Test Panel for electrical equipment testing, for onshore and offshore industry. The panel is installed with type-approved certified test equipment and installed in an orderly manner.

The panel is customised with electrical calibrated testing apparatus according to End-user’s requirement. The panel will be wired according to IEC 61439 codes, using flame retardant cable type and enclosure protection IEC 61892-2.

The typical test panel includes voltage transformer range 0 ~ 300Vac, step-down transformer, electrical power plug & receptacles, circuit breakers, lamp holders, AC & DC Voltmeters / Ampere meters, indicating lamps, selector switches, variable DC Power supply.

Marshal Systems supplies workshop equipment such as test benches with workshop tools and equipment for onshore and offshore industry. Each of our test benches is specially designed, customised and equipped with calibrated type approved measuring & testing instrument. These instrument are grouped and layout in an efficient order for the users. Our test benches are categorised into electrical, electronics, pneumatics and hydraulic test equipment.

We compiled and provide original manuals from manufacturers. These manuals can be translated into different international language, which includes testing devices technical data, drawings , operations, maintenance, spare parts list and trouble-shooting guidelines.

Marshal Systems supplies Hospital Call Alarm system to alert the attending medic when a patient needs immediate attention and assistance from the duty medic in the offshore facilities and marine vessels.

When a patient requires assistance from the medical personnel, he/she activates the call alarm by either pressing a button on the call pendant located near the patient’s bed or pulling the pull-cord located inside the toilet. The hospital call alarm panel located in the medic’s office, will provide visual and audible indications upon activation. This panel will indicate the exact location of the call activation. Another repeater panel which is located in the mess room will provide additional alert to others if there is no response from the duty medic.

Marshal Systems supplies Refrigerated Space Alarm system for crew to alert others in the event of being locked inside the refrigerated chiller / freezer cold rooms in the onshore and offshore Industry. This system is a customised design to meet the operational needs by the crew and based on the general arrangement of the cold rooms.

When the crew was locked inside the refrigeration space, he can easily alert other crew by pressing the call button inside the room, which will provide visual indication and audible sounder outside the rooms. The panel outside the room will indicate the exact location of the call activation. The system can also provide interface to other monitoring system.
