| Abstract: | The pipe-in-pipe type of ocean pipeline has been widely used in Bohai oil fields on the purpose of heat preservation. It has been proved that the single pipe type of ocean pipeline with the polyurethane foam for heat preservation has the advantages of saving great amount of steel, getting rid of erosion problems, reducing the welding work and etc., especially in the shallow water area. During installation of the single pipe structure, shear stresses will occurred on the inter surfaces between the outer concrete casing and the jacket layer, the jacket layer and the heat preservation layer and in the foam. This shear stress may cause split between surfaces of two layers and failure of the foam. Up to now, how to calculate these shear stresses is still a question. A calculation procedure is proposed for estimating the shear stresses between two connecting layers and the stress in the foam, based on the force equilibrium and the displacement compatibility concepts. An example is given to demonstrate the availability of this approach. |
