This paper is referring to performing dynamic analysis for an installation scenario with the bi-linear assumption for the bending moment stiffness, which is the governing component stiffness for the curvature at the touching down point. The dynamic analysis model is set up with SIMLA and both regular and irregular wave loads are applied. The case with linear assumption is also performed to make a comparison with the bi-linear case.A 3-dimensional pipe element with axial stiffness, torsional stiffness and bending stiffness required is applied in SIMLA. For the missing stiffness information, a BFLEX flexible pipeline cross section model is also set up. Both intact case and damaged case are performed and comments are given.Relevant literature studies are also made. Theories are also discussed for the modelling.
