Abstract

Currently, the properties of composites have been harnessed on pipelines in the marine offshore industry. In this study, Marine Bonded Composite Hose (MBCH) has been presented. It is aimed at understanding the stress/strain distribution on marine bonded hoses using local design pressure under burst and collapse cases. This study also investigates on composite material modelling, hose modelling, liner wrinkling, helical spring deformation and two MBCH models- with and without ovalisation. The ovalized model is considered the simplified model in this research. Mesh study was carried out on meshing the hose layers. In this study, local design pressure was considered and not operational pressure. This finite element model was adopted to predict the deformation and mechanical response behaviour of MBCH. From this study, composites could be considered to improve conventional marine hoses. The study findings include identification of buckled sections on the hose, and stressed zones on the helix reinforcement. Highly reinforced hose ends are recommended in ends of the MBCH as they had maximum stress and strain values.
