Saw blade stuck: Why cut the pipe from the bottom?

Reply
I know these guys are smarter than I am so please somebody tell me why you would start cutting the pipe from the bottom? Does it have tension on both ends?

geaux1969, you are 100% correct!! this makes me worry even more about who is in charge of this!!!!!! its like cutting a tree branch. if you cut it from the bottom to much, definetely the blade will get jammed, when the branch, or pipe, starts falling!!! just goes to show you, how intelligent, the so called intelligent people are??????????? we're in big trouble!!!!!!!!! my opinion, these guys are just book smart and ain't got a lick of common sense or logic!!! they sure ain't smarter than you, or me when it counts!!!!!!!!!!

I've cut a few pipes .

The flow of product in a live line causes problems . not to mention the pipe being n a bind .

this crazy idea of cutting this pipe scares me so bad I can't even watch the news!!!!!!

Should have cut from bottom several feet up, then cut from top sveral feet over then make the final cut as I recall when the old man made me cut wood so the saw would not jam.

some the ideas and common since from seem to be to complicated for bp execs to understand .

this looks more like attempts to collect oil rather than stop the spill

these rov tech r very highly trained. the news make it seems so bad and its not. The diamond cutting saw that got stuck on the bop today ,this is a normal thing for this saw to break. Also guys remember their is more then one pipe in this riser. This diamond cutting saw is like a band saw just way bigger. The question to BP should be why this was not done 30 days ago.

\'The shears have just gone back in the water. We have to connect them to the subsea hydraulic power unit (SHPU) and then lower to the bottom. Once there, we\'ll have to reposition other boats and spin our heading around 180 degrees. We\'ll also have to move ROV\'s around. So, it will take some time before we get on the riser.

The diamond wire is off the table for now. The internal pressure and flow, combined with the strength of the riser and drill string inside it, is causing it to get stuck. Personally, I think we can make the cut after the shears are done - but, I don\'t get to make those calls.

The top hat that will be used can handle the jagged edge of the cut. I\'d prefer to take the extra time to do it right - but, someone well above my pay grade has opted to get something done now.\'

The picture above is just a small cutting saw not the saw that was making the cut for the cap.

Cut was being made last night but the cutting wire got in a bind.

to be fair guys that picture is not oriented so you really can't tell whether that is the bottom or topside of the pipe...

okay guys, this is what they did. They cut the riser with shears. Then, they were using the diamond saw to cut it very precisely so that the 'Top Cap' would seal and contain ALL the oil. Since the saw got stuck, they have decided to just cut with the shears the spot the saw got stuck. Now they will use the 'Top Hat' which will not seal as well and some oil may/will escape at the junction of the old riser and the 'Top Hat'.

Hope this clears some things up for you.

Well from my view the saw is stuck just about halfway through the pipe. if you really think about it, the flow is just about restricted to 1/2 of what it was was. It looks like that is the best screw-up they did so far...that is the most restrricted the flow has been since the beginning. It's a shame they couldn't get a few more saws jammed in it to help the cause.

The saw is like a band-saw. It uses a small wire like blade to cut so there is no restriction blocking half the pipe.

Lone Shark, thanks for making me look stupid. I don't need your help...I can do it all by myself. Lol. The saw in the above picture is not a bandsaw-like saw. It is a circular blade like a chop saw , which is solid and it does appear (TO ME) that it is solidly stuck at a point near half-way through the pipe. Sorry about my evaluation of the picture. And Admiral Rabbit, which one are you? Lol. Cheers to you!

I apologize if my comments came across wrong. I was trying to tell you that my no means had the leak slowed. I even attempted to attach a picture of the actual stuck saw but couldn't figure out how to resize it.

It's alright man. I guess the saw posted in the original pic is NOT what was used. I thought it was the actual pic of the stuck saw in the actual pipe being cut, That was what I based my assumption on. I guess the old saying my science teacher in 8th grade taught me still holds true, ' believe 1/2 of what you see and none of what you hear'.
