Based on the previous research results, and taking "Offshore Oil 201" as the analysis object, the hydrodynamic analysis of the hull and stinger structure is carried out. Next, the calculation of roller non-uniform contact force is performed...

... on the flexural behavior of a steel pipe is introduced using nonlinear finite element simulations. Numerical analysis of three roll bending pipe forming process is conducted to consider the residual stresses due to pipe forming. The forming analysis of three roller bending pipe has to consider the material...

... recently, it has also been common to include power phases in the umbilical. The umbilical is then named power umbilical. The task/process that moves the umbilical from a place to another is often referred to as spooling and handling. It is common to guide the umbilical via rollers during this process...

The fatigue limit of roller-worked specimens D2 is 490 MPa, which is higher than that of non- roller-worked specimen MO by 192 %. The above difference would be caused by residual stress and work-hardening due to roller working...
