Ship for recovering ocean waste

Abstract

The present invention relates to a ship for recovering ocean waste. The invention aims to provide a means for recovering waste floating in the sea. Said aim is achieved by a ship ( 1 ) that recovers ocean waste, comprising at least two lateral hulls ( 2 ) which define a basin ( 3 ) therebetween. The ship according to the invention is characterised in that the basin ( 3 ) is open at the two ends thereof ( 6, 7 ) and comprises a plurality of consecutive sections ( 11, 12, 13 ) from the bow ( 6 ) to the stern ( 7 ) of the ship ( 1 ), each of which is provided with at least one collection device ( 21, 22, 23 ), the collection devices ( 21, 22, 23 ) of each section ( 11, 12, 13 ) being capable of collecting objects of different sizes, the sections ( 11, 12, 13 ) being arranged such that a device capable of collecting smaller objects is arranged behind a device capable of collecting larger objects.
