SiMON is at the core of Palladium’s integrated yacht solutions. SiMON constantly monitors literally thousands of data points from all of the ship’s systems and sensors, generating a wealth of data on status and performance. SiMON controllers harvest the data and send it through an Ethernet data network to workstations where the information is assembled, integrated and presented using advanced graphics user interface technology. SiMON serves as a virtual engineer on duty around the clock, constantly vigilant of all critical functions, allowing the captain to focus on the demands associated with navigating and managing a modern vessel.

SiMON provides:

  • Early warning of potential problems before they become catastrophic
  • Constant vigilance over all monitored systems
  • Trending of data to assist in more efficient operation
  • Fuel flow and pressure analysis to optimize speed and course
  • Historical data capture of equipment failures for analysis
  • Comprehensive and flexible alarm system
  • Capability of long-distance monitoring of all alarms through a secure Internet portal with SiMON Anywhere




Engines are, in most cases, the most expensive single item on a vessel – they can be very expensive to repair or replace. SiMON provides continuous monitoring and alarm generation to assist in:

  • Determining the most efficient, cost-effective operating RPMs by fuel flow rates and fuel pressures.
  • Achieving optimum diesel operation and engine loading by use of exhaust temperatures and boost pressures.
  • Providing warnings concerned with clogged strainers and deteriorating water pump impellers through water temperatures and water flow rates.
  • Helping to prevent costly repairs by monitoring gear box pressures and temperatures, and graphical trending analysis which provides clues to deteriorating conditions.

There are two ways in which SiMON can gather information about your marine engines. With the new electronic engines, SiMON interfaces directly to the engine’s electronic brain that runs these engines reading the sensor information from the electronic module. On mechanical engines, or non-electronic engines, SiMON gathers engine operational data directly from its sensors. These SiMON sensors are installed in tandem on mechanical engines in a non-intrusive way, allowing the original sensors to drive the existing analog gauges as backup.



The navigation module gathers data from the ship’s navigation systems and reports on depth, wind speeds, water temperature and GPS satellite signals. The NMEA data is presented to the SiMON computer via the serial port. The actual data being presented depends on the navigation instruments on the vessel.

The depth screen shows the current depth, the minimum and maximum depths recorded for the passage to this point, and depth plotted over time. Minimum and maximum recorded values are displayed with the date, time, latitude and longitude at which the data was recorded.



Each generator has a separate screen, and there may be as many as four generator screens –depending on the installed options. There are six custom gauges in addition to coolant temperature, oil pressure, exhaust temperature, voltage, kilowatt output, and frequency. These gauges show the status of any items you choose to monitor.

SiMON monitors, reports, and issues alarms on power outputs so that maximum generator engine efficiency can be achieved. SiMON also monitors the generator output critical to safe and efficient operation of electrical motors and other equipment aboard the vessel.



SiMON constantly analyzes inputs from sensors thousands of times each second, watching for abnormal conditions. If SiMON receives data that deviates from the presets or is irregular when compared to normal conditions, visual and audible alarms are triggered at workstations on the bridge, in the captain’s and engineer’s cabins, in the owner’s cabin and other strategic locations around the vessel. SiMON can also immediately auto call or page the captain, owner or other designated individual, so that immediate action can be taken to correct the cause of the alarm.
