This was a lot of help. The chart is very handy. The pipeline contains a hazardous gas. Thank you for your help.

I have done some "risk ranking" on my end. We have approximately over 200 above ground sites and I was able to narrow down 20 potential high-risk sites. I looked at proximity to the roadway, AADT, speed limits, population density around the sites to rank each location. Now I'm trying to figure...

Thank you everyone for the valuable input. I am attaching a drawing that shows the barrier that we placed at one of our sites. The 4in PVC were embedded down into the ground about 8ft and filled with concrete, to anchor the barrier.

Actually, I might have been overestimating the impact load. I am looking at accidents, not intentional. I am posting a design done for one of our previous sites. They did not cast a footing on a gravel bed, but did pour concrete inside 4in pvc pipes. The pvc pipe goes 8ft into the ground. My...

Will definitely look into this.

Yes! Correct! This project resulted after the Houston Are (La Porte) fire on the Energy Transfer site. ETC simple placed 4 jersey barriers around their site now. I wanted to look further into what barriers to use, which would be most cost effective and which would inflict less damage to the...

Ok thanks! I'll check Txdot since we will be looking at our houston area sites first.

Right. I was going to assume a mid to large size SUV so about 6000lbs, travelling at 60mph, and hitting the barrier at a 30 degree angle. Typically.

I believe this is why we anchored the barriers on the valve pen where we deployed them. We anchored barriers with pvc and filled concrete to minimize the deflection. I'll post a sketch to allow for better visualization on the anchoring.

I want to say we have between 5ft and 7ft. In some cases. Thanks I will look into longitudinally linking them.

I had not thought of using a berm. I can try and get a sketch uploaded. I have about 20 sites at the moment we need to "protect". I'll choose one out of those.

I'm still in the process of trying to decide what barriers would be the best option. Jersey barriers were considered because I assumed they would be cheaper than the Armco barrier, but I still have to do some comparisons. We have used the armco barriers, jersey Barriers and bollards in other...

Ok good. Point i will check if any of our high risk sites are within any clear zones.

Accidental.

Thank you. The zipper barrier is very interesting! We have one valve site where we placed 4-10ft barriers and each barrier is anchored into the soil with 2-4" sch40 pipes roughly 8ft into the ground. I'm wondering now, if we need to even take this extra step of placing this "anchoring system"...

If making the barrier stiffer would increase the hazard to the vehicle occupants, why are some of these barries anchored to the ground? At the moment i dont know what that movemwnt would be if a car was to strike one of these barriers.

Good Morning All, I am working on a project to place jersey barriers around our above ground pipeline sites to mitigate any risk of impact due to traffic. Most of our sites are located on the side of roads in easements. I have been doing some research and it appears that to anchor a barrier you...

Could you please post your thoughts on this post? The other was deleted. Thank you

Sorry about that. One will be deleted

The pipeline is at a 14ft depth. I forgot to include that detail and the pipeline is in a casing also. They have also potholed our pipeline so we sre certainit is at 14ft deep and the clearances face to face will be 1.5ft. What they told me is the casing is being installed so that while they...
