Marine Engine Monitoring

Marine vessels use engines and generators for propulsion, thrusters and power generation. Monico has standard configurations for the most common marine applications, but can also monitor a variety of protocols and auxiliary equipment to provide complete information that our customers can use to reduce the overall cost of ownership. Marine engine monitoring through Monico is a cost-effective way to help improve a vessel’s operations.

Monitoring within Marine Automation Systems

Marine automation systems provide a ship with one central way to control and monitor its equipment and operations. This system requires data acquisition from multiple pieces of equipment on a ship and the integration of that data into the automation system. Doing this effectively can save costs, energy and materials. Monico has worked within many marine automation systems and marine control systems and can collect, convert and provide data as needed.

Monitoring for Propulsion

  • Bow thrusters, fire pumps, z-drives and other auxiliary equipment that can be incorporated into an overall marine control system
  • Provide engine and associated equipment parameters to the ship’s alarm system, the marine automation system, and wheel house
  • Acquired data supports and improves preventive maintenance programs

Monitoring for Power Generation

  • Monitoring and integrating data acquired through the Gateways reduces maintenance costs, improves efficiency and reduces downtime
  • Data collected supports and improves preventive maintenance programs
  • Engine and generator data is provided to the wheel house and integrated into overall marine monitoring systems
  • Engine parameters and alerts and alarms are provided to the ship’s marine automation system as well as the ship's alarm system

Monitoring for Offshore Supply

  • Bow thrusters, z-drives, fire pumps and other auxiliary equipment can be monitored and integrated into a marine monitoring systems
  • Parameters from engines and associated equipment are provided to a ship’s alarm system, automation system and the wheel house 
  • Monitoring helps improve overall maintenance programs which prevent downtime and reduce costs

Specifics on Marine Engine Monitoring Systems

Monico Gateways are used extensively in the marine markets with a heavy installed base on offshore crew and supply boats. Most generators in the marine market are controlled by Woodward controllers, so they do not have EMCP style GSCs. Genset data is brought in via the dedicated port, which leaves (2) RS-232 ports, (1) RS-485 port, and (1) Ethernet port for gathering data from other system components such as switchgear or Woodward controllers. Each serial port can communicate via one protocol independently, either master or slave. The Ethernet port can communicate via four protocols simultaneously.

In marine communication applications, grounding is particularly important. In most cases, the negative of the engine battery is grounded to the hull which is effective. However, there are times when ship builders choose to isolate the engines from the hull, which causes communications issues. In these cases, we use an isolated repeater to isolate our Gateways from the engine and reduce the chance of ground loops. An added benefit of the isolated repeater is the ability to remotely mount the Gateway up to several thousand feet from the engine. Monico commonly installs color touch screen HMI's in the wheelhouse for a single common marine engine monitoring interface which provides space efficiency in crowded environments.

Most of these types of vessels have automated marine control systems with PLC's. So, the Gateway acts as a data concentrator for engines, generators, thrusters, auxiliary engines, switchgear and other controllers. We then provide usable data to the PLC-based control/alarm system and for display on the HMI's in the wheel house. Our Gateways are compatible with Siemens, GE Fanuc, Allen Bradley, and Omron PLCs without need for additional modules or drivers. HMIS are also used as a stand-alone display system. If a PLC-based control/alarm system does not exist, then a Gateway PLUS and HMI can be used to provide a stand-alone monitoring system.
