You are in the current BP disaster ROV number 348; number 347 is here.

Please DO NOT Rec this diary, rather REC THE MOTHERSHIP instead. She needs your love to stay afloat.

Please be kind to kossacks with bandwidth issues. Please do not post images or videos. Again, many thanks for this.

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!

For a description of the mothership/ROV liveblogging process, check out this thread.

Must reads:
Lax Oversight Seen in Failure of Oil Rig's Last Line of Defense.  Watch video and interactive graphic page, too.   That has one of the best overviews of how the BOP works, and doesn't work, and the management interference that caused the accident.

We have a new 40 page 12mb report on the Macondo well that is an excellent reference on the well design.

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

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.

Go to the Deepwater Horizon Data Summary for a wealth of actual data from the Department of Energy.

This is what BP DOES NOT WANT YOU TO SEE.  The following images are guaranteed to make you SICK AT HEART.

These images are not for the faint of heart - DO NOT VIEW THEM LIGHTLY.

Really, I mean it. Hold somebody's hand. Grab a tissue.

A brief reference guide to nicknames you may see in the ROV diaries:

  • Gertrude, aka Gerty:  the oil volcano
  • Lizzy:  the diamond saw cutter
  • Clampy:  the cute ROV
  • Crunchy:  30 ft shear. bit the pipe, now a movie star
  • Wanda: the dispersant sprayer
  • laundry basket:  yellow thing that brings things up and down
  • Thingy: those things, you know, those things
  • Shiny Thing: those really neat things
  • Ms. Blanche Flo, aka Blanche, aka Flo: the manifold thingy

Thanks to dov12348 for publishing a diary on Oil Terminology.

Technical Info

Here is a tutorial on the sources of well pressure.

H/T to Pluto for finding this much better well casing configuration diagram (PDF).

Here is the initial BP Spill Investigation (PDF) report from 24 May.


The initial approach above was followed by an open hole and a drill pipe magnetic ranging run. After they got to within 5 feet of the blown out well's lower casing they reamed and encased the bottom of the well in cement. They are prepared to start the final 50 feet of drilling  to intercept the annulus which is just past the rock. They may still proceed with reaming through the blown well's casing if only to ensure there is cement at that level. (Photos from The Oil Drum)

On 28 June, Kent Wells provided a dual audio and slide presentation that has an accompanying transcript.

Video feeds we are watching

Tomtech created a set of playlists for VLC player to partially solve the problem where titles do not identify the ROV.

Information on our community can be found in Phil S 33's diary here. That diary having timed out, bigjacbigjacbigjac next took up the cause and posted a new bio diary here. The latest bio diary was posted by Ursoklevar on 7-25 and includes the bios from the previous diaries in alphabetical order by user name.

If you'd like, feel free to join in by sharing a little about yourself there.

in the dark time we held vigil,
we held vigil against the night,
we raged against the storm,
we moved with the force of nature
to right a great wrong,
to howl like the wind,
to hold the line,
to renew an ancient vow,
a sacred purpose,
to recall to life the human spirit,
to safeguard that which is most holy to us,
to forge and reforge,
this, above all, to be true,
to awaken our greater nature,
to commune from the deepest regions of our soul,
to heal this realm, to heal our people,
to guard all life, to guard life,
for this generation,

and all to come,

this is why we hold vigil ~  ~ ArthurPoet ~

  We Are Here
  We are here.
  We are watching.
  Years from now,
  if anyone asks,
  we will tell them:
  We were there.
 
  Maybe it will not matter.
  Maybe nothing matters.
  But if we throw up our hands now,
  maybe someday,
  years from now,
  we will ask ourselves,
  why did we not at least keep watch,
  why did we not?
 
  Maybe someday, some of us
  will talk with someone younger,
  and tell of the time we watched.
  Maybe that someone younger
  will try harder next time,
  will do more next time,
  remembering
  the time we watched.

We're all stunned and horrified by this disaster. Huddling with good people to calculate the damage and monitor progress, have a laugh when we can, share the sorrow we feel, and learn a lot in the process... That's what I'm really here for.

This is how I best cope. And if it turns out to be a useful thing to others, then that's great.

This is where you want to be for discussion, worrying, tearing up, and caring for each other.  It's also where you're welcome to be angry and scream and curse and cry and rant at the criminal negligence and greed that have brought us all together.  Most importantly, though, it's where we can learn from those kossaks among us (I'll not name names for abject fear of leaving one of you out, but you know who you are.) who bring the light of knowledge - sometimes with heat, sometimes without it - and teach us about what's happening beneath our Gulf of Mexico.  On a personal note, I'll ask you to please be kind to each other in our little boats.  There's enough hurt going on outside without bringing it here. - khowell

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.
