Abstract: An apparatus and method for mounting a buoyancy module onto a rigid pipe having a clamp. In one embodiment the clamp includes pads for clamping onto the outer surface or coating of the rigid pip, the pads having a teeth or serrations formed thereon for gripping the outer surface of the pipe. In a second embodiment, the clamp includes 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 includes 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.

Abstract: A throat formed between jaws of a rigid bifurcate gripper can be moved horizontally to receive an edge portion of sheet structure. The gripper is freely tiltable so that application of a lifting force to it will effect tilting of the gripper relative to the sheet structure to bind such structure between the jaws. Normally the gripper is positioned by a counterweight with its elongated throat horizontal. The lower jaw is of reflex angle shape and is positioned relative to the upper jaw so that downward tilting of the jaws will cause them to bind the sheet structure in the gripper throat.
