ABSTRACT

In order to improve the safety of production riser of cylindrical type FDPSO, a riser-tensioner (RT) system is invented. A coupled dynamic model that considering the interaction between riser and tensioner for RT system is developed with micro-element method. The corresponding boundary conditions and difference scheme of the model are derived. ABAQUS software is used to verify the model. With the model, the dynamic behavior of riser system on a float platform in South China Sea is investigated, based on which the value range of riser length, tensioner stiffness coefficient and tensioner damping coefficient are proposed. The results of study can provide effective theoretical support for optimal design of riser and developing new type of tensioner.
