ABSTRACT:
A method of anchoring a line, such as a pipeline, to a support, and in particular a sea-bed, comprises the steps, at each anchoring point, of drilling holes in the support on both sides of the line, bedding piles in these holes, passing at least one saddle clamp around the line, securing the ends of the saddle clamp to the piles, and injecting a filling material, which may be a settable material, into an inflatable body arranged between the line and the saddle clamp.
Devices for carrying out the method are also described.
