Wireless sensor network for determining boat motions and hydroelastic responses

Record type: Conference or Workshop Item (Paper)

A flexible segmented ship model has been tested in a series of head sea wave conditions including regular, irregular and a rogue wave. The model has a typical frigate form and is constructed using a flexible central spine against which four segments are mounted. A three node wireless sensor system, which currently acquires data at up to 30Hz was also attached to the model. These wireless development sensors were supplied as part of the ESPRIT programme and incorporate 9 degrees of freedom using rotational and translational accelerometers and a 3 component magnetometer. The data acquired was compared to those obtained using the traditional pitch and heave potentiometers and a standard heave accelerometer. Overall, the system, although still requiring further development to improve data acquisition rate, performed well with good correlation observed between the various measurement components. The practical advantages are the low mass and low power requirements of such a wireless sensor network
