Fishing Boat Transformed to Harness Energy from Ocean’s Waves

by Niti Nagar

It might be possible to harness the movement associated with the ocean’s natural waves using docked fishing vessels. Researchers are demonstrating this simple idea is feasible using a demonstration vessel currently docked offshore in Western Norway.

Transforming a vessel into a wave power plant requires installing four large chambers, in the vessel’s bow, each equipped with an air-powered turbine. As the waves strike the vessel, the water levels in the chambers rise leading to an increase in air pressure, which consequently drives the four turbines. The chambers respond to different wave heights, allowing greater wave heights to contribute more air pressure. Each turbine is capable of produced 50kW. Using mathematical models and simulations, the researchers expect the plant to produce 320,000 kW per year. Continue reading
