2010 06 05 08:07 updated Sunday morning after watching 3 interviews with the Federal apologist Thad Allen.
This cap was designed with rubbery materials and soft metal to seal against the flange that joins the riser pipe to the preventer stack, but the flange has bolts of different sizes and heights. “It’s all problematic,” the technician said, describing the switch in caps as a scramble.
The technician said that shortly after the cap was successfully placed, Dr. Chu wondered aloud why oil was still spewing from around the bottom. Engineers had to tell him that the leaks were expected, at least initially.
For at least an hour after the cap was in place, the technician said, two remotely operated submersibles pushed on the device from opposite sides, “so it would not move on its own accord” under the pressure of the oil and gas, the technician said.
With regard to the seal, glad these birds don't do my plumbing. If i had a $M i could design and implement a perfect seal. Call Fernco and let them make a custom product in case off-the-shelf options such as the 5631 series cannot meet the challenge. -- john the plumber.
Anticipating the type of pathetic incompetence of those on the job previously explaining why they can't succeed, i can hear high officials like Thad Allen explain, well they can't see the screw head to turn the tighten the noose to close the leak because the escaping oil is blocking our view. Dude -- You will have to devise a means to steadfastly attach the elongated screwdriver head to the screw head to turn -- even in the dark!!
My statement last week was prior to my view of the Blow-Out Preventer cap on the drilled pore at the seabed floor. I do not know, but now presume, the casement/pipe/BOP is well-anchored, obviating need for guy wires. So, it is as simple as mechanically tying the new inverted funnel to the bottom of the BOP, right?
As stated last week,
"casement founded upon said funnel, inverted on the sea bed, aligned by adjustable guy wires suitably anchored."
these words must have been missed by the inadequate experts on the job, pathetically hoping unanchored mass will not rise!
To answer Dr. Chu: when the pressure is less at the bottom opening than inside the funnel, the fluid moves to the lower-pressure area.
Last week's apparently unjustified deference to said experts did not offer this detail:
In order for the gas/oil to rise to the boat, the pressure must be less at the top of the column than at any other point in the column. Chimney science.
While (hopefully) waiting for a larger diameter riser (creating lower top column pressure)
Pump! baby Pump!!
