Abstract
A method and a device for measuring the movement of a subsea pipeline. The measuring device has an accommodating mount anchored in the sea bed to accept the subsea pipeline. The subsea pipeline is liable to be made to move over a determined travel with respect to the accommodating support as the pipelines deforms. The movement has an amplitude that varies according to the deformation of the subsea pipeline. A plurality of frangible elements secured to one of either the deformable subsea pipeline and the accommodating mount. The frangible elements are intended to be broken in succession by the other of either the deformable subsea pipeline and the accommodating mount when the pipeline is caused to move.
