The cables, pipes or any other constructions (1) follow an axis YY and run along this line on the seabed (5). Piles (7) are inserted in the seabed on either side of the construction at a minimum distance (l) from it, forming two lines (12) running parallel to the axis YY. The piles are regularly spaced and a metal cable with tensile strength (81) is attached between the piles. Cylindrical pipes or tubes being laid by a boat are protected by joining two halves of a casing around the pipe and allowing the casing to drop until it rests against the previous casing. A metal grid is tight between the respective piles in both parallel lines forming a coverage on top of the pipe.
