The study reveals power production at MPP from a new design of a harvester device which can be a cost effective solution for many offshore marine industries. It is a safe close type structure which can produce electricity internally without taking the water or air from the atmosphere inside this using a wind turbine as power take off device. For achieving maximum power a new, simpler, faster and adaptive MPPT algorithm proposed here that can be applied to wave energy harvesters that use wind turbine for power take off. It is a modified P&O algorithm which uses the ratio of power change to rotor speed change to adapt the converter duty cycle ratio for next perturbation step and needs no prior idea about turbine but can track MPP faster. Comparing to most of the current MPPT algorithms that assume some complex logic, this algorithm is suitable for application in small wave energy converter powering offshore sensor networks that are distant from land.
