Gulf Oil Spill: BP finally connects mile-long pipe (updated)

Sat May 08, 2010 5:06 pm

Update :
BP finally connects mile-long pipe to begin capping oil spill

http://www.mcclatchydc.com/2010/05/16/9 ... z0o7t6RA3v


The tube "is fashioned from a 4-inch pipe and is inserted into the leaking riser, from which the majority of the flow is coming. While not collecting all of the leaking oil, this tool is an important step in reducing the amount of oil being released into Gulf waters," said a statement from the Deepwater Horizon Incident Joint Information Center.

Note the BP graphic that shows barely any oil "spilling". Here is the real video ...

A novel but risky attempt to use a 100-ton steel-and-concrete box to cover a deepwater oil well gushing toxic crude into the Gulf of Mexico was aborted Saturday after ice crystals encased it, an ominous development as thick blobs of tar began washing up on Alabama's white sand beaches.


Here is plan B.

http://www.businessweek.com/news/2010-0 ... -well.html

BP calls its blowout plan “top kill.” The idea would be to block the oil from rising and direct it back into the well, Fryar said. Scientists and engineers working on the project were even considering untried methods such as injecting golf balls and other debris into the blowout preventer to gum it up, he said.

Yes, "gas hydrates" formed in the box, because of the high pressure down at 5,000 feet.
The funny thing is, I've seen a few specials on gas hydrate, many say it's the next form of "energy" if they can only figure out how to "capture" the methane being converted to frozen hydrate.

I guess they found a way, but not when they wanted to :(

US coal mine tragedy...oil rig...San Antonio gas line fire and refinery fire...Russian coal mine explosion...

Just in time for Mothers Day I'm thinking Momma Earth's a tad upset... And if Momma ain't happy.. :(

The idea of inserting a 4" tube into the 21" riser tube has succeeded. BP says they care capturing most of the oil - though they refuse to say how much.

They have connected a mile long tube to a ship that will collect the oil/NG.

Yes - they have a rubber diaphragm that should hold the oil back a bit increasing the capture. Remember, the drill pipe is in that raiser as well (see the graphic I added at the top).

Anyway, they are going to try the top kill (a.k.a. junk shot) next week.

I have to agree, Gary. The spin/marketing is classic. Right up there with using hazardous dispersants under water so that we won't see the real size of the slick or the effects of the damage until well after BP's lawyers can save the company's hide.

Material Safety Data Sheets for the two most-used dispersants:
Corexit_EC9500A
Corexit_EC9527A

EC9500A contains light hydrotreated petroleum distillates and propylene glycol. It's lethal to fish and shrimp in significant concentrations. It has a 'low' hazard to any human that's wearing gloves, a protective suit, a face splash shield and at least a half-face respirator mask... And it's the least toxic of the two. The 9527 can be absorbed thru the skin and will kill rabbits so exposed.

"ENVIRONMENTAL PRECAUTIONS :
Do not contaminate surface water."

The EPA apparently approved use of products that are known to be environmental hazards because the risk is lower than the damage caused by oil on the beaches and wetlands.

"Apart from marine life, has the Unified Command been able to make an assessment on the effects of the dispersant on the environment?
The harm or toxicity of dispersed oil in the environment is generally associated with the oil rather than with the dispersant alone. However, use of dispersants breaks up a slick of oil on the surface into smaller droplets that can go beneath the surface. When applied on the surface before spills reach the coastline, dispersants will potentially decrease exposure for surface-dwelling organisms (such as sea birds) and intertidal species (such as mangroves and salt marshes), while increasing exposure to a smaller population of aquatic life found deeper in the water. It is unknown if dispersed oil has toxic implications to the human population because bioaccumulation through the food chain has not been evaluated."
