Theoretical and experimental analysis on tensile property of offshore floating oil hose

An offshore floating oil hose is a composite tube made of structural layers in different forms and with material properties from inside to outside. The layers are integrated as a whole after sulfidizing so that they are free of cracking and relative sliding during normal use. Based on assumption of layering, bonding, plane section and uniformity for the tube and simplified treatment of rubber materials and reinforcing rubber portion of nylon cords, ABAQUS finite element analysis software is used to conduct an analysis of overall tensile properties for the hose under research and development with the stratified analysis method. Finite element calculation results are compared with static tensile test results. Although relative error between them is about 20%, it reflects tensile properties of the hose structure to a certain extent and is of significant guiding significance for tensile properties estimate and structural optimization during the hose structure design.
