Chinese Finger
Device used during flexible pipe installation that consists of a meshed structure that grips around the flexible pipe outer sheath. NOTE The mesh is configured such that the higher the load applied to it, the tighter its grip.

Chinese Finger
Chinese fingers are typically used when transfer of tension is required from lifting devices to the flexible pipe. The Chinese finger typically consists of a cylindrical mesh of wire rope that wraps around a portion of the flexible pipe length and is connected to lifting equipment. An example of such a configuration is shown in Figure 38. The Chinese finger is designed such that the grip on the flexible pipe increases with increased tension applied to the Chinese finger. The Chinese finger is designed to impart load onto a flexible pipe principally in an axial direction.
