Abstract
The shipping transport industry is a leader in the transportation industry. Even if the efficiency of the ships in terms of fuel consumption has increased in the past years, the recent Paris agreements intend to reduce significantly the fuel consumption of the ships. Consequently, new systems has to be designed in order to lower the fuel consumption. This project investigates the feasibility of various technologies for generating electrical energy by exploiting the ship heave motion, which can’t be controlled. It outlines the existing technologies developed in marine renewables for energy harnessing from waves and tidal currents. Two technologies are studied deeper in order to integrate them on board. The first one is a linear generator named SEAKERS, which is proved inefficient as the motions of the ship are damped too much for the device to produce enough energy in order to be interesting. The second system is based on the use of a Wells turbine to create a system like an Oscillating Water Column inside the ship. The first power studies show that it is a promising system, in so far as the energy harvested may represent half of the power of a generator set. Finally, a basic economic study of this system is conducted to have a global approach on this system. Keywords : energy, heave, ship, linear generator, turbine
