Abstract: A mathematical model for simulation of a flexible marine riser connected to a floating vessel is presented. The model is used for dynamic analysis of marine operations which include a riser and a floating vessel. The riser can be freely hanging from the vessel or fixed at the bottom. The vessel can be freely floating, moored by anchors or dynamically positioned. The performance of the riser model is evaluated by a comparison with results from a simulation study published by the American Petroleum Institute. Finally, a complete three dimensional, irregular sea-state analysis is presented to illustrate some of the capabilities of the simulation concept.
