BBS and BBS/CCS Bumper for Bundled Road Bores

 BBS and BBS/CCS Bumper for Bundled Road Bores


    JSI's BBS system has reached its 10th year of existence!  That is 10 years of protecting lines that will be a part of a bundled directional drill.  10 years of supporting your CP systems to keep space for the current to reach your pipeline 360 degrees around your line.  

    BBS and BBS/CCS are simple to install, requiring no special tools or training.  All that is really needed is a propane torch with a broad bushy flame and a means to wipe dust and dirt off of the pipeline prior to installation.  

    The BBS includes as its line item:
  • suitable durometer bumper material pre-cut to length
  • main sleeve to hold bumper in place
  • three inch wide sleeve for added front end protection
  • two part epoxy bonding agent

Bundled Bumper Spacing

 Spacing Options for Bundled Bore Bumpers

Nowhere to hide if these bumpers don't work.  In person, the space was clearly visible and the silence of the lines NOT rubbing on one another was deafening.

Here they go.  Bumpers still intact and in the same exact place when they came out of the ground 1500 feet away.

     When selecting your bumper spacing, I've seen a number of different philosophies.  First and foremost - it is important to share this disclaimer:  JSI never recommends bumper spacing.  In the first place, there are numerous factors including the flex in the pipe (which will be impacted by OD and wall thickness) then there is the depth and angles of the bore hole.  Because of those things; it is impossible for me to make a recommendation - that is a decision for the end user to make.

     But when we look at the multitude of jobs that have used our BBS system, I notice there are a few schools of thought out there.

  1. Some folks are conservative.  They want a bumper every 8-10 feet.  They know how expensive directional drilling is - how expensive their pipe and coating are - and they don't want to take any chances with pipe on pipe damage -- or CP failures. 
  2. Some folks seem to choose to put a bumper every 15-20 feet regardless of pipe OD.  
  3. Some folks carefully calculate all the factors involved:  pipe flex, bore radius, number of lines in the bundle, etc and they come up with very specific spacing requirements:  as an example I've seen every 25 feet on a 20" line and every 20 feet on an 8" line.
    So there are many strategies that our clients have used.  What is your strategy going to be?

Bundled Pipe Bumpers Case Study


Pipe Bumpers / Bundled Pipe Bumpers / Road Bore Bumpers / Bundled Directional Drill Spacers - CASE STUDY

“I’ve got a problem and you’re the only company I’ve heard of that might be able to help me.”  In all honesty, we get calls like that pretty often!  It is always great when a customer has a difficult problem and we can offer a fairly simple solution.
In this case, the customer had a bundled directional drilling project in Texas.  Pipe was already being strung up, but they didn’t know how they were going to prevent pipe collisions from causing a bunch of damage during the pull through.  To make matters even more complicated, they were pulling four pipelines at once:  16”, 16”, 12” and 10”.  The customer needed a solution…and he needed it fast. 
After several phone conversations, several emails and a face to face meeting, our customer was sold on the BBS system.  Material was going to be needed in about a week.  We were able to call in some favors with some of our suppliers; call in some extra labor for the manufacturing and hit the ground running the very next day.  Problem solved! 
Like any pipeline project, there were surprises along the way.  Fortunately, there was a great crew in place for this project we had an excellent, quality focused contractor.  We had an inspector who combed through every detail with a fine toothed comb.  We had an active and involved end user.  We had a veteran road bore crew.  And of course, we had us – Joint Specialists – with decades and decades of experience with pipeline construction materials.

The four pipes were strung up side by side and marks were made where the bumpers were to be installed.  The pipe is then preheated to 140F and the bumpers are put in place. 
The two part epoxy is mixed and applied to the warm pipe
 

The heat shrink that acts as the main bumper anchor is shrunk in place.
Pipe Bumpers 
Altogether, each bumper installation took 3-5 minutes.  Once all of the BBS systems were installed, the pipe was bundled up and ready to be dragged through the mud.  This is where we ran into our biggest obstacle.  Just about 400 feet into the hole…the mechanism that grabs the pipe to pull it snapped.  We were told this almost never happens.

Here was the culprit:  the broken piece which caused the pipe and BBS system to travel an extra 800 feet underground (400 of it in the 'wrong” direction!)
As a result, the pipe bundle that had gone 400 feet into the hole….now had to come 400 feet back out of the hole in the opposite direction.  In addition, backing the pipe out was going to be a trickier proposition as it would be done with side booms. 
Wow, this was going to be quite a test for the BBS system.  400 feet into the hole.  400 feet backwards out of the hole.  Then 1700 feet back in and through the hole.  Beyond all of that though, we were going to get a golden opportunity.  Most of the time, a pipeline enters a bore hole and is never seen again.  Here we were going to get to inspect our system first hand after a 400 feet round trip journey into the Earth!  Is our system really as good as we believe it is?  Let’s find out!
The inspectors and end user representatives were excited about this rare opportunity as well.  They were going to get to closely inspect a few dozen BBS systems.  Would any be missing? Were any bumpers left behind in the mud?  Has the pipe been crashing into the other lines, or not?  Every BBS system looked the same.  All perfect.  All exactly as they’d looked pre-bore (well except for the caked on mud!).  Down the line the inspectors went; running their fingers along each side of the bumper to make sure it was still in place, still standing and still functioning.  We had a 100% success rate.

So there you have it.  Does our BBS system work?  Absolutely.  Do you have someone else presenting some kind of solution that they ‘say’ works? If so, please ask them to prove it with documented photographic evidence!  I’m confident that no one else can!
