Dynamics of Flexible Hose Riser Systems

Abstract

The paper describes a highly effective method for computing the dynamics of the catenary-shaped suspension of flexible hose systems. The method accounts for a number of nonlinearities, it is 3-dimensional and it is performed in the time domain. The paper addresses the analysis method and demonstrates its effectiveness on a sample flexible riser analysis.

“…Collapse performances were experimentally and numerically investigated in Caleyron et al (2017) to show the installation effect was positive. FEA turns out to be an effective method (Owen and Qin, 1986;Fyling et al, 1998;Chai et al, 2006) in riser global analysis and rod elements (Chen et al, 2011;Ruan et al, 2017) or beam elements (Guo et al, 2018) have often been adopted for the modelling of risers. In addition to common wave configurations, Amaechi et al, 2019 carried out the dynamic analysis on hoses in the Chinese-lantern configuration attached to a Catenary Anchor Leg Moorings buoys.…”
