Experimental study on tensioned wire maintenance concept for tidal current turbine

Abstract

Even tidal current power can extract electricity from ocean current, it is to be installed and operated in a high current speed regions. Having a limited accessible window, it is very important and critical to minimize the retrieval and installation duration. Also the driverless scheme is very efficient to reduce any hazard to the diver during the maintenance in the limited working hours. The maintenance scheme is to be developed as per the site conditions and also the device configurations and specifications. In this paper, a tensioned wire maintenance concept developed for HAT (Horizontal Axis Turbine) device is introduced with the experimental approaches at various current speeds.
