Pipeline crossing bund wall / containment dike solution?

Pipeline crossing bund wall / containment dike solution?

Pipeline crossing bund wall / containment dike solution?

(OP)
In storage tank farms pipelines to and from the storage tanks cross an earthen bundwall / containment dike mostly simply as is - buried -.
I think that this is an undesirable situation as it makes regular inspection of the buried pipeline very difficult.

I am about to try and design a new type of crossing which would keep the pipeline available for inspection.
However, I don't want to re-invent the wheel and I wonder if any of you have got some examples of solutions that have worked in the past?

Note: The pipeline cannot simply be passed over the bund wall as the installed pumps would not be able to handle that.

Many thanks for your thoughts.

RE: Pipeline crossing bund wall / containment dike solution?

adbla,

I can't give you a proven solution, but as no-one has answered:-

My thoughts were of a precast concrete panel in place of the earth bund. Not the entire bund - just where the pipe passes through the bund. That would leave most of the pipe uncovered. It would need to be designed to have adequate strength of course, and the pipe penetration would have to be sealed somehow.

RE: Pipeline crossing bund wall / containment dike solution?

I would suggest wrapping the pipe with a general tape wrap.  Your local paint company should be able to steer you in the right direction.  I am a pipeline engineer and we are required, by DOT, to install tape wrap approximately 3' below grade up through the transition zone and we usually continue wrapping the pipe 1' above grade (total of 4').  We do this with our interstate pipelines.  If the surface is prepared to the manufacturer's recommendations, this should work fine.  We've been doing this for many, many years with great success.  We also do this in our storage tank farms.  I guess you could always build a tunnel for the pipe to pass through, but that would probably be cost prohibitive.

Good luck !
