Dynamics analysis of marine riser using different approaches

This paper proposed two methods to analyze marine riser, which is Finite Element Method (FEM) and Extended Kalman Filter (EKF) method. Due to environmental disturbances and ship motion, the occurrence of riser's large deflections will bring fatigue problems and propagation cracks, which will lead to environmental disasters. Compare the two methods to derive structural parameters of riser, such as total mass matrix, stiffness matrix and damping matrix. Simulation results will be carried out using the two methods to validate the effectiveness of the methods.
