Resumen de: WO2026019313A1

The present invention relates to an underwater pumping device and method capable of moving over the seabed and of converting wave energy into high-pressure seawater pumping action for reverse osmosis desalination. The invention makes it possible to transform wave motion into linear motion by means of surface floats and an underwater float oscillating with the waves. The floats drive pistons that draw in, filter, and compress seawater. The movable pumping device is capable of positioning itself in synchronisation with the period and celerity of the waves by sliding by means of an anchoring system rolling on a conveying pipeline that carries the pumped water directly to a reverse osmosis station. The pipeline is anchored to the seabed by means of a series of deadman anchors. The sliding mechanism makes it possible to retrieve and remove the pumping device from the water for weather-risk prevention and for cleaning and maintenance.
