Abstract:
1. A buoyancy module and an apparatus for mounting the buoyancy module onto a rigid pipe configured to transport liquid or gas hydrocarbons, the apparatus comprising: one or more coils together defining a plurality of turns, each turn of the plurality of turns surrounding the rigid pipe, the one or more coils being configured such that the turns of the one or more coils contact and clamp onto an outer surface or coating of the rigid pipe so as to resist slippage of the one or more coils over the rigid pipe; and each coil formed from a resilient material and configured to be wound around an outer circumference of the rigid pipe such that each turn clamps onto the rigid pipe; and the buoyancy module is secured to the apparatus and positioned over the rigid pipe, the buoyancy module configured to provide a buoyant force to the rigid pipe.
