ABSTRACT The invention is concerned with a method of and device for anchoring a line, such as a pipeline, to a support, in particular a sea bed. The method of the invention comprises the steps, at each anchoring point, of drilling anchorage holes in the support on both sides of the line and bedding piles in the holes. A central curved part of at least one saddle clamp having lateral connecting parts is passed around at least a portion of the periphery of the line and an inflatable body is arranged in its deflated state between the line and the curved part of each saddle clamp. The lateral connecting parts of the saddle clamp are secured to the piles, and a filling material is injected into the inflatable body to provide a jacking effect displacing the line, with respect to the support, piles and saddle clamp, to its anchored position. The device for carrying out such a method comprises, for each anchoring point, a pair of piles to be embedded in anchorage holes drilled in the support on both sides of the line, and at least one saddle clamp having a central curved part and lateral connecting parts for securing the saddle clamp to the piles. At least one inflatable body is secured in the concavity of the central curved part of each saddle clamp by securing means, the inflatable body having walls formed of flexible material and being provided with a valve for injecting a filling material into the body. me invention enables one to ensure proper anchorage of a pipeline to the ground, irrespective of the nature of the ground, even if another pipeline has already been laid at one point on the length of the new pipeline.
