A Method for Analysis of a Prototype Articulated Multiline Marine Production Riser System

This paper describes a newly developed nonlinear computer program that predicts internal reaction forces and motions of a multiline marine production riser exposed to wave and current forces. The paper also presents an analytical method that accounts for large geometric displacements and nonlinear wave forces. A simulation of the response of a prototype articulated multiline marine production riser during a mild tropical storm illustrates the program’s capability.
