HMS supplements the experience and knowledge of bridge personnel by quantifying and recording ship responses to environmental conditions.  This data can help officers determine appropriate courses of action that will minimize the possibility of structural damage in the event of extreme environmental conditions. 

​

HMS utilizes a variety of sensors including  pressure gauges, strain gauges, clinometers and accelerometers to quantify ship responses.  Data from the sensors is displayed in real-time on the HMS Computer located in the bridge console.  In addition to real-time displays, the HMS Program displays historical summaries for key sensors.  The data is presented in graphic and statistical formats to facilitate quick interpretation.  The HMS Computer also receives real-time data from integrated bridge systems that contain information such as ship speed, course and GPS coordinates.  All data is continuously recorded. 

​

The recorded data can be used to create ship response reports for individual voyages or analyzed to determine ship responses during severe weather.   It can also be used to identify and quantify critical events such as bow emergences.
