for those interested, the Skandi Neptune video feed is showing what's happening as BP replaces the cap on the blowout preventer and takes other action - it's pretty interesting some times, boring at others. If you don't have the sites bookmarked, look for 'spillcam" or go here
The page on Rep Markey's site was smaller than normal. I went here to pick a non-embeded web stream.
From what I've read, the BOP had one blind shear that a joint of pipe could foul. It would seem that a second shear would have been plain common sense. My automation systems use dual path circuits to control control power to things that can hurt one. Single point failure in a BOP is idiotic. JMHO.

Every time...no exceptions...every time Ive gone to one of the camera feeds, I get "waiting for video"

Wes has got a good one. You haven't? Doesn't seem like it is coming out so fast to me and never did. Maybe it's the depth... I would think the video would be blurred from the gallons their talking a day. Doesn't seem like they are stomping on the gas so to say as much as I would imagine. There must be unknown problems that makes it look that way.
Bet I could come up with a smoother PTZ camera.

A good what? Black window with "waiting for video" in it isnt good?

Single point
The usual configuration is one set of shear rams, a second section with pipe rams and finally the annular "bag" BOP that is usually the top set. So the congenial setup is three separate BOPs. One set on the top that can close around various diameter tubulars, a second set to close around the drill pipe and finally the shear rams that are capable of shearing off the drill pipe, although usually only between tool joints (at each end of a joint). So there are usually three separate and distinct BOP's installed. Each one with its own closing system.
This is how a land rig is configured. For sub-sea the BOPs may be configured as one large device but I believe that the three separate systems are still incorporated into the device.

Sitting a BOP on top of a piece of pipe topside is fun enough. Under a mile of water with cameras, it must be really fun. Those things are huge and heavy.

Hummm...true indeed.
