The Loading Calculation on Sea Floating Hose-string System with Static Mathematic Model

The stress of sea floating hose-string system is very complicated due to the effect of multidimensional force-field. By adopting the beam column theory, a static mathematic model of hose-string is established, and the deflection of hose-string, tension force, bending moment and shear force are obtained with the model. The analysis and calculation results can provide a theoretical foundation to the dynamic analysis of this system on design.
