| Summary: | Although installing offshore pipelines by reel-laying method is eases and cost-effective,
still conceal some of plastic deformation into the pipeline which may, in combination with ageing,
affect strength and ductility of the pipe material. Therefore, reeling pipelines that internally
pressurized is addressed in this study sifting parametrically pipelines stiffness to prevent the
ovalization and bifurcation produces during spooling of (initially straight) or laying of (initially bent)
pipe. A combination of composite materials is examined and number of bending cases at the limit of ovalization and bifurcation is investigated. It is demonstrated that composite pipeline exhibit more bending stability than Steel. Results on the strain energy release in the reel lay system are presented,extending the findings of previous works on the methods of spooling and laying mechanism. |
