Capabilities for modelling offshore marine systems1. The strain rate-dependent nonlinear stiffness should be considered for the taut-leg mooring system.Dynamic analysis and control of offshore marine systems using OrcaFlexA presentation to the SUPERGEN 7th Doctoral Training Programme Workshop Control of Wave and Tidal Energy Converters Lancaster University, LUREG, Room A74 Eng & Computer Roomsby Steve Dalton and Sarah Ellwood, Orcina Ltd 26th February 2010Ĭontents1. Considering the nonlinear stiffness in the taut-leg mooring system, the slowly varying responses in the surge motion and mooring tension were observed in the response spectra. When applying the catenary mooring system, the nonlinear stiffness little affects the motion and line tension responses. We analyzed the effect of the nonlinear mooring line stiffness on the platform motion and mooring line tension responses by assuming three mooring materials with the linear, strain-dependent nonlinear, and strain rate-dependent nonlinear stiffnesses.
#ORCAFLEX OC4 SEMI SUBMERSIBLE VERIFICATION#
A very good agreement was drawn from the comparative study for the two verification platforms. We compared the experimental and numerical results of two floating platforms with the results calculated from the code. We introduced theoretical background to develop a new code.
#ORCAFLEX OC4 SEMI SUBMERSIBLE CODE#
Through the development of a floating platform-mooring line coupled simulation code that allows simultaneous consideration of the strain- and strain rate-dependent nonlinear stiffness, this paper aims to examine the effects of the nonlinear stiffnesses on platform motion and mooring tension responses. The synthetic fiber rope is a mooring material that is increasingly used, but few commercial codes are known to reliably implement the nonlinear stiffnesses of this material.
