Dyena PRO simplifies long term recording of vessel structural accelerations, providing scientific data without having to trawl through months of spreadsheets. When an event occurs above the programmable threshold, raw data from before and after the event is stored in a single file alongside the daily overview spreadsheet and a Google (GOOGL) Earth 3D map trace.

The Dyena PRO unit constantly monitors the shock and vibrations received by the vessel structure and stores the data to the onboard solid state memory, alongside position, speed, heading and time. Sampling at 1,200 Hz, recording the peak and RMS averages every second and storing individual daily records stored alongside a Google Earth 3D map trace, this provides the user with a concise and easy to interpret overview of vessel operations.

Raw data is continuously buffered and when a significant event is observed Dyena PRO records the accelerations leading up to the event as well as those afterwards at 1,200 Hz providing the user with the complete record of the relevant acceleration data. There is no longer any need to review a mass of spreadsheets, as any data from events that exceed the user configurable threshold are presented in a clear and formatted manner with all the information in a single file along with the daily overview spreadsheet and 3D map trace, meaning the user can build up a complete picture of the vessels use and the cause and effect of any incident.

With prices starting below £1,800, the Dyena unit will store up to 10 years of data, providing the user with a detailed record of any structural events, as well as an indelible log of the vessels' use and operating characteristics. This data can be examined at anytime for the details surrounding any accidents, or simply to provide the owner with a record of operations.

Dyena PRO has recently been fitted to BAE Systems (BAESY) Small Boats new Pacific 24 Mk IV Rigid Inflatable Fast Rescue craft for trials of the vessel and measuring the effectiveness of their shock mitigating seats. With the data from multiple systems synchronised via GPS time, scientific studies of the structural response of the hull and systems can be easily performed without the need for expensive equipment or engineers to be present at every test. With Dyena PRO valuable data can be collected whenever the vessel is used and downloaded later at a convenient time.

Current users of Dyena systems include the U.K. Royal Navy, U.S. Navy, Sunseeker and RNLI.
