| Summary: | The reel laying offshore pipeline installation method is known to be easier and cost effective, but the method may induce some plastic deformation into the pipe, thus affecting the strength and ductility of the pipe material. However, the design and modeling ofapplied bending
loads to the pipe during spooling of (initially straight) or laying of (initially bent) pipe has become a
great challenge and are addressed in this study,sifting parametrically pipelines stiffness. It is demonstrated that rigid pipeline requires higher spooling loads, but indeed rigidity improves the laying effort without the need of applying tension, thus making it more tractable during the
straighteningstage. The paper also emphasizes on pipe free-end deformations and offset of bending,which extends the findings of previous works on spooling or laying control. |
