PCT No. PCT/DK81/00007 Sec. 371 Date Sep. 16, 1981 Sec. 102(e) Date Sep. 16, 1981 PCT Filed Jan. 16, 1981 PCT Pub. No. WO81/02054 PCT Pub. Date Jul. 23, 1981.An apparatus (2 or 3) for jumping a moving object (10) from one place to another. Fields of application include protection of submarine installations such as pipelines (1) and cables, from damage due to dragging anchors (10) and fishing gear. The apparatus comprises a plate-like device (2 or 3) that is unstable with regard to a horizontal force over a certain strength. The deformation of the device (2 or 3) caused by such horizontal force results in a steeper direction of the resultant (14) acting on the edge (6). The frictional resistance combined with the passive soil pressure (7) thereby become able to withstand the horizontal force from the moving object (10). Subsequently the device (2 or 3) carrying the object (10) will turn around the edge (6) and thereby lift the object (10) over the installation (1). Several alternative designs of the device (2 or 3) and a method of installing it are disclosed.
