Abstract

This paper concerns about the exceed response analysis of slender structure by freak wave. A method for 3-dimensional dynamic analysis of marine slender structures such as risers and pipelines is developed by using Euler parameters. Large deformation of flexible slender structures is described by means of Euler parameters. Euler parameter method is implemented effectively in an incremental-iterative algorithm for 3D dynamic analysis. Newmark numerical integrator is used for time-domain integration.
