| Abstract | |
Considering that time domain solutions for the dynamic analysis of a riser are very time-consuming tasks, frequency domain solutions are studied as a possible alternative, mainly in the early stages of a riser design. However, to solve the dynamic riser problem in frequency domain it is necessary to remove the non-linearities, such as, the viscous damping. The aim of this paper is to study and discuss alternatives for the damping linearization and compare the results obtained for a typical lazy-wave configuration with a full nonlinear code results.
