Bending moment analysis of coiling of floating hose
2019, 6 (6):
During non-operational period, floating hose coiled on the drum of oil tanker or FPSO, it is easy to deform or even destroy its function, the coiling analysis of floating hose is an indispensable segment in the process of analysis, calculation, inspection and verification of floating hose. Firstly, the basic assumptions of the model and the calibration criteria suitable for the floating hose are determined, and the floating hose is simplified reasonably. Secondly, the model is built on ABAQUS, and the stress and strain of each layer of the main pipe of the floating hose under the coiling moment are obtained. Finally, according to the principle of checking and approving, the strength of each layer of the main pipe is checked. The results show that the utilization ratio of each layer meets the design requirements, and the reinforced bar meets the strength requirements in use.
