Vessel Motion Monitor - VMM
Based on many years of knowledge, experience and development as well as a large number of delivered sensors for attitude determination worldwide, KONGSBERG now offers a software tool to analyse motion and weather data.
The Vessel Motion Monitor (VMM) system interfaces a range of sensors for accurate monitoring of any point on a vessel. Sensors typically interfaced are Motion Reference Units (MRU), meteorological and navigation sensors. Extensive recording functionality is also included.
Motion limit monitoring
The VMM 200 enables the user to monitor the motion of any user defined point of interest on the ship. The system will give alarms and warnings when the motion level exceeds user-defined limits.
The VMM 200 performs statistical analysis of the time series and presents the result to the user in real time. Based on the sensor input over a given time period, statistical values are calculated and presented. Typical values are:
- Average values and periods
- Standard deviation
- Root Mean Square (RMS)
- Maximum and minimum values
The Vessel Motion Monitor includes extensive recording functionality. The amount of data variables recorded and the duration of the recording period is only limited by hard-disk capacity. It records data on a binary format at a selectable data rate (maximum 10 Hz). A tool is available for converting the binary data to ASCII-format for further post-processing of the data in a preferred software package like Excel, Matlab and similar.
- Data input from MRU H & 5 units and Seapath 200
- An unlimited number of user defined monitoring points available
- Recording and playback functionality
- User defined alarm and warning limits
- Statistical analysis
- Time-series plots
- Serial and Ethernet input and output of sensor data
- User configurable Human-Machine-Interface
- A range of sensor protocols are supported
The Vessel Motion Monitor is a two module solution with a Processing and an Operator Unit connected via Ethernet. The Processing Unit runs all critical computations independent from the user interface on the Operator Unit to ensure continuous and reliable operation. Several Operator Units can be connected to the same Processing Unit in a networked architecture. On each operator unit, the operator can select views that fits his operation.
On request the system can be delivered with interface to wave radar. On the Operator Unit 2D wave radar spectrum, significant wave height, wave period, length and direction will be shown in one of the views on the screen. Optionally also weather forecasts can be monitored in the VMM 200 with trend on wave height and direction together
