The global maritime data tracking and shock measurement specialist, Dyena, has launched a version of their monitoring system aimed at supporting Naval Architects who are involved in running vessel trials.
Dyena OFFSHORE Premium records detailed information on a vessel’s motion, position and performance, through various parameters including pitch, roll, yaw and accelerations in 3 axes. With sampling up to 1000 Hz, all data is recorded alongside GPS data to include SOG, COG, time and position. With upto 2 years memory capacity, the system provides high resolution data for development and long-term trials.

An Autonomous Underwater Vehicle (AUV) operates independently from the ship and has no connecting cables while ROVs are connected to an operator on the surface host ship by a load-carrying umbilical cable which provides communication and control.
