ASSEMBLY AND METHOD FOR TRENCHING UNDERWATER CABLES
An assembly (1) for trenching underwater cables, comprising a cutting and lifting device (7) for cutting and lifting at least one seabed clod (11) from the seabed (4) avoiding this seabed clod (11) from separating from the remaining part of the seabed (4) but freeing up an excavation path (P) adapted to create a trench (6); an excavation device (5) for excavating the seabed (4) where the at least one seabed clod (11) has been cut and lifted to form said trench (6) producing excavated material; a depression device (19), adapted to guide a cable (13) which is to be trenched in said trench (6) for laying it in said trench (4); a suction device (18) for sucking up said excavated material; a diffusion device (20) for distributing said excavated material and filling said trench (6) once said cable (13) has been laid on the bottom; a recirculation device (39) which collects the excavated material from said suction device (18) and sends it to said diffusion device (20) so as to isolate said excavated material inside said trench (6) forming a closed circuit for the excavated material which, having been collected in the formation of the trench (6), returns to the trench (6); a device for restoring the at least one seabed clod (11) in the site thereof by closing said trench (6) at the top and preserving the area above said seabed clod (11) avoiding the dispersion of said excavated material outside said trench (6).
