Abstract: A piston assembly including a piston body pivotally connected to a connecting rod by a wrist pin. The wrist pin includes a sealed cavity therein partially filled with a heat transfer medium. The heat transfer medium may be composed of a fusible alloy. The sealed cavity may be comprised of discrete compartments. The wrist pin may be integrated with the connecting rod and share a conjoined sealed cavity therewith so that heat transfer medium can draw heat effectively away from the piston body.

Abstract: A subsea line clamp assembly (1) has a body (10) having an axis and a clamp member (50), assembled in segments around a subsea line (3), and tethered to a subsea anchor (5). The clamp member (50) is movably located within the body (10). The inner surface of the body (10) and the outer surface of the clamp member (50) have respective tapered portions as part of teeth (32, 72) arranged to inter-engage. Adjacent teeth (32, 72) may be separated by axis-parallel portions. The clamping force on the subsea line (30) can be maintained at a consistent clamping force throughout the service life of the subsea line (3), despite the actions of creep and compression acting to reduce the outer diameter of the line (3).

Abstract: A piston (20) and connecting rod assembly includes a piston crown (24), a piston skirt (26), a connecting rod (22), and a bearing insert (50). The piston skirt (26) is a component separate from the piston crown (24) and is connected to the piston crown to provide a piston body. The bearing insert (50) is a component separate from the piston crown (24) and the piston skirt (26) and is fixedly disposed within the piston body. A bearing surface of a connecting rod contacts the bearing insert (50) to thereby movably associate the connecting rod (22) and the piston body (20).
