Abstract: The offshore discharge floating hose，the only oil transferring channel of FPSO，is a composite of rubber hose，and
has a complex structure and material diversity. However，there lacks of relevant design specifications and standards，and the
theory system is still not intact. The model of the offshore offloading floating hose for the typical structure was established
with the finite element analysis software；the sensibility of the cord winding angle on the tensile and bending properties was
analysed. And the effect of the structure angle to the tensile and bending on different conditions was obtained. Finally，we
verified the actual floating hose with experiment，and compared it with international OCIMF standard. The results can guide
the future pipeline optimization design and provide a reference for the localization of the discharge floating hose.

Key words: FPSO, offloading discharge hose, structure angle, tensile, bend
