Abstract
Disclosed herein are novel buoyancy modules for attachment to a cable, pipe, or umbilical. The buoyancy modules include a pair of module bodies adapted to mate with each other. Each module body has a recess adapted to engage a single bolt tensioner and at least one of the module bodies includes a longitudinal channel running the length of the module body. Further, the module bodies include one or more pads positioned within a pad containment channel. A plurality of single bolt tensioners may be positioned within the recesses of the module bodies and tensioned to impart a compressive force such that the module bodies contact each other, generating a predetermined displacement of the pad and thereby imparting a known clamping force that results in a desired clamping pressure being applied by the pad to the cable pipe or umbilical.
