Safety at Sea
SeaWise Stability Monitor
The new SeaWise safety device developed by Hook Marine is designed for vessels to warn of loss of stability while at sea.
The biggest loss of life in the fishing industry is due to the sinking of vessels when they lose stability. The new SeaWise safety device developed by Hook Marine is designed for small craft to warn of loss of stability while at sea.
The SeaWise monitor logs the loss of stability through continuous roll period measurement, and sets off an alarm when the metacentric height reaches the threshold of 0.35 m specified by the IMO.
Advanced software, specifically developed for the application, enables SeaWise to discount the motions which interrupt the rolling period.
The current Mk II SeaWise monitor was developed with the assistance of grant funding from Lloyd’s Register Foundation, Trinity House, and the European Maritime & Fisheries Fund, provided by the Marine Management Organisation.
Model tests with the on-board sensors were carried out at the University of Edinburgh using the wave basin at the engineering laboratories, and sea trials which developed from that work have proved successful with different types of fishing vessel.
