Where this attaches to the stack, we want to make sure no leaks there. the bigger question, though, and one of the reasons they are increasingly saying they may not use this as a permanent fix is theyre worried about a leak down here along the sea bed floor where the well goes deep underground. nothing they can do at this point. theyre worried as they stop the pressure up here it puts pressure back down and perhaps there was some damage in the explosion down along the sea floor. thats one thing ...

Capacity to be able to accommodate the flow rate which the government estimated and still systems to be 35,000 to 60,000 barrels a day. to that end, the capping stack off the kill and the choke lines, together with the kill and choke lines off the legacy bp deepwater horizon give us four outlets from which to produce and what we intend to do is from the kill and the choke line on the legacy b.o.p. is to produce to the helix producer and the pisces, which are floating production units that will t...

Stack which stopped the flow directly out of the top of the capping stack. we then closed the kill line. it left a choke lin. and the way this is set up, the choke line is going to have a variable valve we can close slowly and be able to assess the pressure readings as tkwoe that. in the process of doing that, we discovered there was a leak on the choke line. at that point, we terminated -- we terminated the test that the point so we could determine the cause of the leak and repair that. overnig...

>> did bp have any quality control on these parts before they installed them on the cap that would allow them to detect a leak, a hole or anything like that? if not, will there be in the future or what were they if there were any? >> im not sure i can tell you exactly on thatpert pop well get that information and get back to you. i do know this. a lot going on here has been designed and engineered for the first time to deal with this particular problem. the capping stack was a custom made stack ...

Not sort of fake projects where youre building stuff for no reason. jon: liz, thank you very much, good talking to you. jenna: were starting with a news briefing here in admiral thad allen with an update of whats going on in the gulf. lets listen in: >> consider outcomes, once that was done i gave the order with slight modifications to include some requirements for seismic testing, akao*sing testing, to go ahead and proceed last night. the sequence on how that test proceed was to take the q4000 ...

And start to slowly close the choke line and take the pressure readings at that time, as we intended to do. just to let you know what happened, this is the choke line. off of the capping stack. as you know, this comes out of the assembly and goes up. if youve seen the video, this is that big yellow device with the curve pipe that goes up with the oil coming out of it. it connects back to the capping stack down here and there is an ass assembly where this meets together. the entire choke assembly...

Range of 60,000 barrels a day based on the new rate we developed years ago. they provided a plan to us. the capping stack that is on right now is actually part of the containment plan that we ordered them to provide. while we had the opportunity to potentially shut in the well, if the readings are correct, what this really does for us is give us four different outlets to go to four different production platforms and the capacity to us low us to cover 60,000 to 80,000 barrels a day, which is abov...

>> dispersance are certainly an issue. they have their own inherent toxicity, much more mild than the oil itself, but the combination of the oil and the dispersant actually has a combined cumulative toxicity thats more than the sum of the individual toxicity. so theres questions about whether to use the dispersant at depth in the first place and on the surface as well, but the other thing i think going on this morning that they installed this brand new capping stack and it sprung a leak within a...

Diameter. theyre very cautious. thats the reason were not coming off the mid-august prediction. its going to be very methodical. in relation to why this wasnt done earlier, im assuming youre talking about the capping stack it had to be designed, tested and brauought to site an as you see, there are, obviously, some leaks were having to fix and things like that. a range of capping devices that have been developed probably over ten, or all developed under different scenarios and we can actually re...

Metphorically put your thumb over the garden hose. in this case it is called a capping stack. three ways for the oil to leave that capping stack and then very slowly close that third choke line down and then do pressure readings. if we have very low pressure readings, it would be the equivalent of putting your thumb over the garden hose and the water is going some place else. if we get high pressure readings that is indication that the wellbore is in tact and that all then relates to how much mu...
