The stinger elements are modeled as points which are held by links/tethers in both vertical and lateral directions. Fortunately the program OrcaFlex is capable to do both analyses. First step is a static analysis and the second is a dynamic analysis. The S-lay pipeline installation method will be taken for the analysis in the 2 case study of this thesis. Then guidelines and constrains for establishing the different installation methods are matters of our concerns.Ĭalculations for two different cases related to documenting installation of steel pipelines and flexible pipelines in sideway current are included. Therefore in the next step we introduce various installation methods for offshore pipelines and what may govern the choice of an installation method / scenario. Installation also plays an important and vital role.
In the literature survey stage we elaborate on basic information about different types of offshore pipelines.
