Dynamic riser analysis - Oil and Gas
Virtual classroom
Available dates:
12-14 July 2022
Specialisation course
About the course
This course provides learners with the key components, loads and interfaces affecting dynamic riser response and how these are simulated within the analysis. In addition to riser configurations and components and their analytical modelling, this course also presents the dynamic loads on risers from vessel motions, waves and vortex shedding and the analytical methods for their assessment. The critical failure modes for rigid and flexible dynamic risers are presented in this course, while also covering analytical methods for prediction of failure. This course also details industry software packages for undertaking dynamic analyses and a detailed break-down of setting up and running a dynamic analysis using a leading industry package, OrcaFlex.
Explaining the interfaces between the riser, the vessel and seabed and their influences on dynamic response, this course is suitable for engineers wishing to undertake or commission analysis of rigid or flexible dynamic risers.
