Method and apparatus for mounting distributed buoyancy modules on a rigid pipeline

摘要

An apparatus and method for mounting a buoyancy module onto a rigid pipe having a clamp means. In one embodiment the clamp means includes pads (2) for clamping onto the outer surface or coating of the rigid pipe, the pads (2) having a teeth or serrations (3) formed thereon for gripping the outer surface of the pipe. In a second embodiment, the clamp means comprises one or more coil springs formed from a resilient material adapted to be wound around the outer circumference of the pipe. The method for mounting a buoyancy module onto a rigid pipe comprises the steps of reducing the outer diameter of the pipe at a location of the pipe to which a buoyancy module is to be attached and subsequently mounting a buoyancy module at such location.
