I am looking for papers on the probabilistic analysis of scour around submarine pipelines.
I have good experience and I work around 24 years in this field in the industry please advise me what can I help you.
Hi Prakash
It seems I did not adequately explained my question. I try again.
Marine pipelines laid on the seabed (i.e. not buried) are subject to current.action. Depending on the soil type and current velocity, the soil beneath the pipeline may be washed away which is known as scour. If such phenomenon takes place around a pipeline, then the pipeline loses some of it support and large span may appear. The newly formed span may be too large such that pipe would collapse under its weight and the weight of its content. It is also possible that vortexes appear around the pipe and pipe to vibrate in sympathy. Such vibration may cause fatigue.
At the design stage such possibility must be investigated and carted for. generally equations for scour is used to determine the long term possibilities. My question is how reliable are such equations. and how one does reliability analysis for scour.
