Engineering of flexibles

About the course

Providing specialist knowledge of flexible risers and flowlines, this course will give design engineers a deeper appreciation of installation and operational conditions, enabling them to design pragmatically. Those operating or installing flexibles will gain an appreciation of associated issues and design limitations, whilst manufacturers will benefit from a greater understanding of how their products are used. 

Covering riser geometry from seabed to surface, the tutor will teach you the skills required to write accurate specifications for flexibles and develop your understanding of how the different wire profiles affect performance. Related equipment and how the effects of installation and operational loads will also be discussed. 

We have gained permission from Orcina to facilitate the use of OrcaFlex, its industry recognised static and dynamic analysis software, during this course. You will have the opportunity to get hands-on with the software and practice simulations and analysis, reinforcing knowledge learned.

Learning outcomes

  • Distinguish and select appropriate materials and equipment
  • Evaluate how FPSO and SPM design affects the choice of riser system
  • Apply theories and lessons learned to projects
  • Compare the different types of software available
