“…In recent years, Kuroiwa [10] through combining the indoor shrinkage ratio experimental study and finite element numerical software calculation, has analyzed the contact mechanics characteristic of the pipe-in-pipe system, found that the tension of the riser pipe will decrease under the action of the tube. Simon Falser [11] analyzed the relationship between the transfer efficiency of the axial force and the inclination of riser based on Kuroiwa's research. He found that the riser's inclination has little impact on transfer efficiency of the axial force, riser's axial force and radial clearance of pipe-in-pipe system are independent to each other.…”

Due to its unique character, Coiled tubing technology is widely used in various fields of marine oil and gas operations. But as the stiffness of coiled tubing is small, and the marine environment is complex, it is easy for the coiled tubing to destroy or cause an accident. Therefore we need to study axial load transfer characteristics of coiled tubing in the Marine riser to ensure safety and reliability of the operation. In this paper, through establishing the finite element model of coiled tubing down into of marine riser, axial load transfer law of unfixed boundary and fixed boundary coiled tubing was analyzed. Analysis results show that within fixed boundary condition, coiled tubing axial load transfer efficiency would be higher than that in unfixed boundary when the injection force is greater than the helical buckling critical load.Index Term -Pipe in pipe; Load transfer; Finite element analysis.

The article describes the result of theoretical research aimed at assessing the loads and operating conditions of a Coiled Tubing pipeline injecting water, suspended to the mining platform of Lotos Petrobaltic. For this purpose, appropriate calculation models have been developed using the Finite Element Method (FEM), taking into account the nature of the analyzed object and its loads. The analyzes were carried out for two pipes (previously operated and newly proposed) differing in geometrical and strength parameters. The research was carried out for selected directions of load on the pipeline (originating from sea waves) and various variants of attaching the suspended pipeline to the mining platform.

“…Recently, Kuroiwa et al [19] found that riser's tension would be reduced affected by inner pipe. Simon Falser et al [20] found that tilt angle would affect CT's axial force transfer behavior very few and radial clearance has nothing to do with riser's axial pressure. As all the achievements are based on a 'fixed' outer pipe, it would be difficult to apply these results into marine pipe-in-pipe system, in which CT is injected into a floating riser [21,22] …”
