The Tapered Floating Hose is suitable for a variety of applications, it is mainly used in the parts that need to be bent in the pipeline. It can be used to connect the floating pipeline and the underwater pipeline, it can be applied as the hose connecting the pipe at the stern of a Cutter Suction Dredger and a floating pipeline, and it can also be use in the Bow Blow Hose Set of a Trailing Suction Hopper Dredger.

The transition from floating pipeline to underwater pipeline is realized by taking advantage of the good flexibility and moderate stiffness of Tapered Floating Hose and Slope-adapted Hose. The adopted layout scheme is: Floating pipeline + Tapered Floating Hose + Slope-adapted Hose + Steel Pipe + Slope-adapted Hose + Underwater Pipeline. During use, the hose set presents a lazy "s" bending shape, and can adjust its bending state to adapt to the water level difference caused by rising tide and falling tide, while ensuring the piple line is unobstructed. This is a successful layout scheme that has been practiced in China. In dredging projects out of China, there is another pipeline layout scheme for the transition from floating pipeline to underwater pipeline, which is: Floating pipeline + Full Floating Hose (SG 2.1) + Full Floating Hose (SG 1.8) + Full Floating Hose (SG 1.6) + Full Floating Hose (SG 1.2) + Buoyancy-free Hose + Underwater Pipeline, which is also an applicable scheme. Comparatively speaking, in the current competitive market, the layout scheme with Tapered Floating Hose has a much lower cost and is a cost-effective choice.
