For a practical global dynamic analysis procedure, this paper also introduces a partial hysteresis modeling (PHM) method, by which only a small number of local regions are modeled with bending hysteresis curves. W Orcina The OrcaFlex VIV Toolbox User Guide to the Time Domain Models 1. As a result, the interlayer interaction is found to have a considerable impact on the fatigue damage of flexible risers. Based on the proposed method, three comparative studies are performed to investigate the effects of interlayer interaction.

Basic understanding of ORCAFLEX software used in Mooring Analysis of Offshore installation. wind turbine components and OrcaFlex to model the floating vessel forces. 1 OrcaFlex User Group 2003 Slide 1 of 8 OrcaFlex - Modelling Contact Clearance Models Seabed clearance (from line centreline at a node) Line. In this paper, Part II, the proposed analytical model is extended to the global domain of riser configurations that is to say, a Multi-Hysteresis Modeling (MHM) method is proposed The proposed method employs accurate and realistic bending hysteresis curves with consideration of shear deformation and axisymmetric loads. Inspection of FAT of hoses as per GMPHOM 2009 including Minmum Bending Radius Test, Bending Stiffness Test, Torsion Test, Hydro Test, Vaccum Test, Electrical Test etc. bending and torsion effects are omitted in both the FAST and.

#ORCAFLEX TORSION SERIES#
For the precise prediction of the bending behavior of flexible risers, Part I of this series of papers proposed a new analytical model that successfully models the interlayer interaction. Continuous interactions of tensile armor layers and anti-friction tapes trigger the slippage of helical wires and a highly nonlinear hysteric behavior in bending. Flexible risers have been widely utilized for the transfer of oil and gas products from the well to the production unit.
