In 2006, the Portuguese utility supplier EDP launched an international RFT to install in a wave power plant in the new breakwater on the river Douro mouth.

The power plant, of the Oscillating Water Column (OWC) type, would have a capacity of 1 MW (4×250 kW) with Wells-type turbines, 1.8m nominal diameter, equipped with two fixed blade distributors; thrust and counter-thrust bearings; instrumented for monitoring condition, pressure and air flow rate.

The Power take-off unit (PTO) would be protected by a butterfly-type insulation valve; nominal diameter 1.8 m; hydraulically actuated.

Kymaner, in association with EFACEC S.A., was the successful bidder of the Tender but the Portuguese Government decided to cancel the construction of the power plant, due to the risk of generated noise disturbance to the nearby residential area.
