Thesis

Scour and sedimentation around subsea pipelines

Summary

In an effort to help reduce conservatism while maintaining pipeline reliability, my research aims to advance knowledge on the effect of scour and sedimentation on the safety and performance of offshore pipelines.

I am reviewing and summarising data from real offshore pipelines and comparing my observations against existing scour theory (which is almost exclusively based on physical and numerical models).

Why my research is important

At present a lack of detailed knowledge concerning the influence of scour and sedimentation on the embedment of offshore pipelines has restricted efforts to account for these effects in design. This can lead to either overly conservative (and costly) design for stability, or non-conservative design, depending on the approach adopted by the designer. The same lack of understanding can lead to poor pipeline design when accommodating thermal expansion of the pipeline, planning for corrosion prevention, or designing for flow assurance.

Funding
