Wave Powered Navigational Buoy Electrical Power Assessment during Open sea trial

In India, the navigational buoy is a standalone system to guide the ship in the navigational channel of the port. Conventional navigational buoy is usually powered by solar energy and the continuous operation of the buoy may be affected during prolonged rainy weather and cloud cover. The indigenously developed wave powered navigational buoy produces electrical power from ocean wave and the same is utilised to electric power up in situ components as marker lamp, oceanographic sensors and its data logger along with a wireless communication system. Based on the results of experimental studies conducted and results obtained during open sea trials, this paper elaborately describes about power take-off system and power assessment of power module which includes sizing of battery, integrated sensor and power circuit, power mangement etc., In this paper elaborated about energy generated during open sea trials in the year 2019 (June-Novemebr). This buoy generated electricity which is self sutatined for power requirement of the buoy. This standalone wave powered navigational buoy is successfully demonstrated for longer periods at all weather conditions in Kamarajar Port limited, chennai. It may be useful product for ports and harbours in India as a stand alonewave power device.
