Rules of the Road

  • We take volunteers for subsequent diaries in the sub diaries or ROV's as we have playfully coined them.
  • Please rec this mothership diary, not the ROVs.
  • Please be kind to fellow kossacks who may have limited bandwidth and refrain from posting images or videos.

PLEASE visit Pam LaPier's diary to find out how you can help the Gulf now and in the future. We don't have to be idle! And thanks to Crashing Vor and Pam LaPier for working on this!

To repeat: please refrain from commenting in this mothership diary - it only serves to point people in the right direction.

Must see: I received a set of links to the massive video library collected by Josef Gerbils of The Oil Drum.

Deepwater Horizon BlowOut V is new

Deepwater Horizon BlowOut & Oil Spill:
Deepwater Horizon BlowOut II
Deepwater Horizon BlowOut III
Deepwater Horizon BlowOut IV
Those include many videos from our crew and others.

40 page 12mb report on the Macondo well

Deepwater Horizon BP Oil Spill Reference Material - from Whitis is the best source for everything.. The quantitative data diary has also been moved there.

Six Steps that Doomed the Rig is an excellent graphic from the New Orleans Times Picayune.

The motherlode of technical data Kairos brought us was removed, but the 19 mb 48 page BP Accident Investigation Overview and the 12 mb 147 page Confidential TransOcean Assurance Analysis of the BOP with detailed control diagrams starting at page 56, are still available.

Kossak Sillia gives a concise explanation of the mothership and liveblog:

This diary, that is, the mothership, forms the hub from which you can reach the other diaries. Or, think of it as a table of contents in the front page of a book. You use this diary to find a link to the latest discussions. You can also find links here to past discussions (previous diaries) if you wanted to read them.

The actual liveblog diaries (in this case playfully referred to as a 'submersible' or ROV) is where the discussion is--once one of these gets so long that its size is cumbersome, they start a new one. So if you wanted to join in to the most current discussion, you'd click the most recent link. But they leave the links there so that people can still go back and read the older ones if they wish.

The reason for this setup is that it prevents the recommended list from being filled up with many diaries on the same topic. Instead just the mothership will appear on the rec list where everybody can find it, which they can use to navigate to the latest discussion. (That's why we are asked to "rec" the mothership but not the other diaries, just reduces confusion.)

I hope this is sort of what you were wanting to know...

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.

  •  A huge thank you to the Daily Kos community (61+ / 0-)

    for your support of the BP Catastrophe liveblog. The Gulf Watchers greatly appreciate your recs for the Mothership and participation in the ROVs.

    After the ROV activity being nearly nonexistent the day before yesterday things started changing yesterday afternoon. The small seep with white bubbles we were seeing around the wellhead increased slightly yesterday. Also, it is now seeping black stuff (2 minute video), presumably oil.

    Gulfwatcher, rja, caught a 12 second glimpse of an pinkish-purple eel seemingly swimming backwards.

    In Thad Allen's briefing yesterday he said that they are continuing to remove boom where it isn't needed and working with parish presidents in Louisiana to plan for long-term recovery. Also, next week there will be a full briefing on future plans for monitoring subsurface oil.

    According to Allen, they are checking to see if they can move more quickly to the final kill by eliminating the step of cementing the annulus from the top.

    With that, let me give you an update.  When I spoke last, I talked about discussions that were going on with BP regarding our desire to make sure we knew the condition of the annulus before going ahead with the relief well.  And there was extensive discussion between the BP engineers and our science team regarding the ability to perforate the casing above the cement that was put in during the static kill and put cement in at the top to obviate the need to be concerned about any seal problems at the top of the annulus.

    Again, we still need to go in from the bottom, because we're not absolutely sure of the condition of the, what it is between the annulus and the reservoir, if there's communication there.

    In the last 48 to 72 hours, in extensive work and consultation between the science team and the BP engineers, we've come up with an alternate method to ensure us that we won't have a problem with the seal between the annulus and the blowout preventer.

    And in order to speed the process up, but also ensure that we had the right pressure controls on the well, I've signed a directive out to BP earlier this morning, directing them to take a series of measurements on the well head that would allow us to ascertain whether or not the seal in the ring – in the casing hanger were in place and had not lifted and, if that was the case, then to be able to put what we call a sleeve over the top of it that would basically walk that down to the point where it could withstand over one million pounds of pressure and would obviate the need to be able to cement the annulus at the top.

    And subject to BP providing me the plans and the results of those tests, that would allow us to go ahead and proceed more quickly without having to cement the top of the annulus.  And based on a revised schedule from BP, we might be able to accelerate going ahead and finishing out the relief well.

    This remains a work in progress this morning.  I'm giving you what we have as we've got it.  We'll continue to update everybody as we move forward, but just to summarize, we have found a way to be able to measure or assess the condition of the seal and the casing hanger at the top of the wellhead.

    And as a result of those tests, it appears that we can put a device over the top of the wellhead that basically locks it down.  That means that entire casing hanger cannot be lifted up and, therefore, allow any free communication between the annulus and blowout preventer.  That, in effect, would substitute for our need to be able to cement at the top of the cement plug that's already there and the annulus.  It will allow us to proceed with the relief well more quickly.

    I do not have an exact timeline, because I've directed BP to provide that to me.  That is a work that's in progress right now, so I will not be able to give you exact dates for how much this will be accelerated over my previous briefing, but subject to the installation of this sleeve over the top of the well, it would allow us to go ahead and then proceed with the relief well.

    And with that, I'd be glad to take any questions you have any for me.

    Operator:   Your first question comes from Kristen Hays with Reuters.

    Question:   Yes, hi, Admiral.  Good morning.  I just want to be clear on this – what seems to be a change in procedure here.  This would be some sort of a cap that you would put at the top of the well and, therefore, you would not have to inject – go down into the well, perforate the casing, inject more cement, before you resume drilling on the relief well?  So you'll be able to resume drilling on the relief well sooner than you had thought a couple days ago, right?

    Admiral Allen:   That is correct.  In essence, we're going to put a ring or what they call a sleeve around the top that'll lock that casing hanger in place, will not allow it to move.  There is always concern that when we pressurize the annulus, that  casing hanger would lift, allow free communication between the annulus up into the blowout preventer.

    Cement in the annulus will be one way to preclude that from happening.  But after some consultation and looking at various alternatives, the BP engineers and our science team agreed that if we could ascertain that the casing hanger had not been dislodged, in other words, where we need it to be, then we could actually put a sleeve around it and basically lock it down.

    And the order that I issued to BP, I ordered them to take what are called lead impressions.  You go down, you take an impression of the top of the casing hanger.  And then that allows you to take measurements on where its location is.  Based on that measurement that they took, it appears that the casing hanger has not been dislodged to the point where we'd have a problem with the seal, so we just need to lock it in place, and that would substitute for the pressure control that cementing the annulus would have provided.

    Gulfwatcher, Tomtech, got to the heart of the matter and Allen's answer doesn't inspire warm and fuzzy feelings about leaks around the wellhead.

    Question:   Hey, Admiral.  If they're not going to be venting the annulus and they're going to be putting a lockdown sleeve on it, will that put a high stress pressure on the rock and the mud surrounding the annulus?

    Admiral Allen:   They don't believe to the point where it'll jeopardize the ongoing operation.  And, again, we're not going to know exactly the condition of the annulus until we do the intercept.  But any pressure downward is not going to have nearly the effect of excess pressure upward that could not be tolerated by those seals, so this is considered the preferred way ahead.

    There is discussion about the lock down sleeve plan in this thread.

    A horrifying thought, but BP helped develop environmental curriculum for California schools.

    BP, the energy giant responsible for the largest offshore oil spill in history, helped develop California's framework for teaching more than 6 million students about the environment.
    ...
    "I'd hate to see how a section in future textbooks mentioning the BP oil spill will look," said Lisa Graves, executive director for the Wisconsin-based Center for Media and Democracy, a critic of so-called "greenwashing" techniques by corporations to make their products appear eco-friendly.

    "I think it's very worrisome because their fundamental goal is to profit from energy and not to teach children," Graves said.

    BP has been booted from the FTSE4 Good ethical investment index. Given BP's "don't give a dang" track record of killing its employees through lax safety and its repeated attacks on the environment one wonders why in hades BP was on any "ethical" investment list.

    Food & Water Watch, a watchdog group sued to have BP's Atlantis platform shut down until it meets safety standards.

    The environmental group claims BP acquired in excess of $10 billion in oil and gas profits by "falsely certifying’’ to federal regulators that Atlantis was built according to engineer-certified designs. The lawsuit seeks treble damages for the violations, or roughly $30 billion.
    ...
    The U.S. Bureau of Ocean Energy Management, which oversees offshore drilling, will decide after its ongoing investigation is completed whether to shut down Atlantis. Kendra Barkoff, the agency’s spokeswoman, had no comment today on the lawsuit or the investigation, which Salazar said in June might be completed by mid-September.

      JOINT INDUSTRY SUBSEA WELL CONTROL AND CONTAINMENT TASK FORCE oil and gas industry recommendations "to address future needs and requirements in equipment, practices or industry standards to augment oil spill control and containment."

      This task force will review intervention and containment at the seafloor along with processes for conveyance and processing to the ocean surface. The primary focus will be on single wells in deepwater and on operations that can occur after a BOP has failed and ROV shut-in attempts have failed or are not possible. The primary objective of subsea containment is to minimize the total time and volume of hydrocarbons discharged to the environment. Each incident needs to be assessed and the best available response and containment measures employed.

      Consideration will also be given to containment of open casing or casing leaks. Although some technical solutions can be applied to subsea producing wells and templates, these will be focused
      on in future work. The review will not include Blow Out Preventers (BOPs) and control systems such as Emergency Disconnect Systems (EDS), Autoshear Systems, and Deadman Systems all of which are covered in the Offshore Equipment task force. The task force will focus on well control and containment procedures including well shut in, kill methods, subsea capping, and collection & processing methods.

      Included are specific near-term response items designed to mitigate catastrophic subsea oil spills:

             * inventory equipment and capability that has been proven fit for purpose through use in response to the Macondo blowout and acquire all appropriate equipment into a Containment Company;
             * review the services and contractors that are advertising immediate containment capability and contract those best able to deliver near term response to the Containment Company;
             * review available equipment for containment that is available "off the shelf" from manufacturers and acquire appropriate equipment; and
             * review vessels and vessel contracts from the Macondo response and contract for those vessels necessary to provide near term containment response.

      NOTE:  This report is devoted to containment and mitigation of an oil spill event, not the prevention of same, which other investigative panels are addressing.

      A second, related, JOINT INDUSTRY OIL SPILL PREPAREDNESS AND RESPONSE TASK FORCE report includes -- among others -- these recommendations.

      While there are many variables inherent in every spill response, the approach outlined below minimizes the likelihood of oil impacting sensitive shorelines while maintaining responder safety:

      The primary strategy should be to address the spill as close to the source (and as far offshore) as
      possible first controlling the subsea spill, then, applying appropriate quantities of dispersants.

      Oil that surfaces nearest the wellhead should be addressed through surface application of dispersants and, when conditions allow, mechanical recovery and/or in situ burning.  Near the wellhead, these response activities need to be coordinated closely with other spill response and well containment activities.  Beyond the immediate vicinity of the well head, aerial dispersant application should be used to treat oil that escaped the near-field mechanical recovery and in situ burn efforts.

      Further from the wellhead both dispersant application and mechanical recovery using vessels of opportunity should be deployed to combat floating oil. Accurate targeting of oil through visual observation and remote sensing from manned and unmanned aircraft, satellites, and other platforms should form a key part of the response.  Finally, protective booming of priority areas should be conducted as identified through shoreline assessments and cleanup team
