Глубоководный горизонт

National Geographic HD

00:00:03

there is an explosion on a drilling platform in the Gulf of Mexico, the

00:00:08

surviving employees leave the platform,

00:00:11

unable to stop the release of the

00:00:15

dump, I said to myself, and either you will get up

00:00:19

or you will remain lying here and die

00:00:23

two hours earlier, tests showed

00:00:25

that the drilling rig is safe, now it

00:00:30

remains to be investigated how the

00:00:32

drilling platform is worth 560

00:00:35

million dollars could have exploded

00:00:36

leading to the largest oil spill

00:00:39

in the sea

00:00:42

why this happened modern drilling

00:00:45

platforms competent company

00:00:47

exceptionally experienced personnel about this

00:00:50

should not have happened

00:00:57

disasters do not happen just like that they

00:01:01

are the result of a chain of decisive

00:01:03

events we will reveal the fateful decisions and

00:01:05

read the last seconds before the disaster the

00:01:08

oil platform deepwater horizon

00:01:11

events reconstructed in full

00:01:13

accordance with official

00:01:14

eyewitness accounts

00:01:16

Gulf of Mexico sixty-six

00:01:20

kilometers from the coast of Louisiana

00:01:24

drilling platform deepwater horizon

00:01:33

April 20, 2010

00:01:37

five o'clock in the evening

00:01:42

senior drilling foreman Miles Randy and the

00:01:46

head of the drilling department of the

00:01:48

trance company already he is on the platform with exemplary

00:01:50

safety indicators,

00:01:52

we were part of a high-ranking

00:01:55

group of specialists from British Petroleum and the

00:01:57

transaction

00:01:58

owner of the work performed a general walk-through of

00:02:00

the platform, the

00:02:01

last place of the walk-through was the modules to the

00:02:04

work site where the

00:02:06

procedure for pressure testing of well 1753 was already carried out,

00:02:13

your drilling rig is

00:02:17

43 days behind schedule, a specialized

00:02:20

drilling platform is preparing for

00:02:21

disconnection from the finished well,

00:02:25

the work is almost completed, the management of a brave

00:02:30

team, the work of the drilling foreman, Wyman

00:02:32

Aguilera, he needs to make sure that the well will

00:02:35

not give way to the furnace if there is a leak, gas and

00:02:38

oil will be thrown towards the

00:02:40

platform with enormous force, he is not carrying out

00:02:43

plans, there were pressure measurements on the

00:02:45

monitors, unusual pressure readings in

00:02:47

the well,

00:02:52

the pressure continues to rise as the

00:02:59

6-hour shift approaching, the

00:03:01

rig's slope room is filled with

00:03:03

night shift employees, the

00:03:06

subsea supervisor, Crisp Leeson,

00:03:08

is responsible for the subsea system of the drilling

00:03:10

platform, he needs to be aware of

00:03:12

all the problems with the well, one swab,

00:03:15

we run around, he was convinced that something was wrong

00:03:19

8300 kilopascals I just can’t

00:03:21

explain this Wyman villar believes that there is a

00:03:25

leak at the well I’m convinced we have problems and

00:03:28

just branded at the door but his shift

00:03:31

is ending

00:03:36

night shift supervisor Jason Anderson

00:03:41

something is wrong with this well she is

00:03:43

sending us a signal

00:03:50

Anderson is taking measurements again

00:03:53

re-carry out the crimping procedure

00:04:03

you looked, I see Jason said why do

00:04:06

n’t you go get a bite to eat and and answered

00:04:08

and really I’ll have a bite to eat and will be back when he

00:04:11

said not necessarily if I

00:04:13

have any problems with this

00:04:15

test then I called 1858

00:04:25

welcome gentlemen you know which one

00:04:27

occasion we gathered we gathered to

00:04:29

celebrate our operation in the conference room

00:04:32

randy and the room again joined the

00:04:34

dignitaries who

00:04:35

congratulated the management of the rig on its

00:04:37

impeccable

00:04:39

safety record over the past seven years this

00:04:41

drilling platform is never just him

00:04:43

gentlemen

00:04:44

applaud yourselves and the waters of your efforts for

00:04:49

seven years a medal wasted by them or

00:04:51

tomorrow lin staff

00:04:55

and in the meantime Anderson is

00:04:57

measuring the pressure they again released the

00:05:01

pressure in the well and are now waiting for the

00:05:03

results one person is responsible for this

00:05:08

and this man randy and the hall

00:05:11

did a great job in the market we are in the gardens

00:05:16

[applause]

00:05:20

Anderson finished the measurement he is sure

00:05:23

that the Medici wells are his

00:05:27

last shift

00:05:28

at the rig, he is going for a promotion,

00:05:30

plans to be there next morning

00:05:32

[music]

00:05:37

2110

00:05:42

she is there models leaving the work site

00:05:45

on my watch it was nine ten social

00:05:48

said Jason before we

00:05:50

disconnect the platform I need go

00:05:52

work on the crane, he asked, are you sure it’s an

00:05:54

unnecessary task, I answered everything

00:05:57

is fine

00:06:02

[music]

00:06:10

before starting the night shift,

00:06:12

Randy and the hall calls Anderson, results of

00:06:16

pressure testing and sulfur will be there, he said that

00:06:18

everything went well quickly, they

00:06:21

checked the pressure for half an hour, there were no leaks I said

00:06:24

ok, I need my help, he answered no,

00:06:27

as before,

00:06:28

saying I have everything under control, go to sleep,

00:06:31

everything is fine, as he was completely sure

00:06:34

ort that all the grafted muse background were

00:06:37

in order, the poster was

00:06:44

21 hours 31 minutes,

00:06:49

it was worth preparing for disconnection when the

00:06:53

drilling team noticed an unexpected

00:06:56

increase pressure this thing is going

00:07:01

crazy never seen anything like this

00:07:08

21 1:41

00:07:15

below deck Chris's assistant prize then

00:07:18

appears on the screen of the drilling surveillance system

00:07:20

eset said Chris what kind of

00:07:25

water is this assorted about itil maybe

00:07:27

it comes from that hole

00:07:30

on and minutes would get said to the hedgehog dirt,

00:07:37

I grabbed the handset and called the

00:07:39

drilling site, there were no answers,

00:07:41

I called all three lines

00:07:45

when already myself and

00:07:47

[music]

00:07:53

mud burst out of the well from a height of

00:07:56

74 meters and fell on board the

00:08:03

drilling staff know that in order to

00:08:05

avoid a disaster, the well must be

00:08:07

immediately taken under control

00:08:09

they shut off the valves in an attempt to

00:08:12

stop the dirt and flammable gas

00:08:13

escaping from the well

00:08:31

[music] should I

00:08:39

come here randy quickly the team

00:08:43

lost control

00:08:44

the well is gushing out the salon and after

00:08:55

Steve’s words were only we had a

00:08:57

coordinated interruption

00:08:58

I was cut off by you all and but said

00:09:03

randy

00:09:04

is needed your help will now

00:09:12

stand quietly and almost and windlessly, but

00:09:15

highly flammable methane

00:09:17

has condensed on the surface of the drilling rig; just

00:09:20

one spark is enough for it to

00:09:22

ignite

00:09:28

as soon as the gas reaches the engine

00:09:30

room of the diesel engine, they are overloaded and

00:09:32

fail 21 hours 49 minutes,

00:09:59

a fountain of burning oil soars hundreds of

00:10:02

meters into the sky,

00:10:09

street 126 people they rush to the

00:10:12

lifeboats

00:10:18

Randy and the call there is no bus among them

00:10:24

I said to myself either you will get up

00:10:26

or you will stay here lying and died

00:10:29

mom your right leg is stuck about

00:10:33

full left with all my might I freed I

00:10:35

then felt something similar to the

00:10:39

air

00:10:44

America I reached the corridor the city and

00:10:47

everything that I first took for air

00:10:48

was actually methane and I felt

00:10:51

droplets, it was a scandal, so I had a

00:10:53

mad look on my face like your measles, he Abel was

00:10:59

seriously wounded, he took a couple of steps over

00:11:05

my shoulder, he was told

00:11:07

to get down,

00:11:08

walk and save yourself with office

00:11:12

go back when I said no we won’t

00:11:16

leave you here

00:11:27

before leaving the drilling platform

00:11:29

Chris the landing party must try to stop

00:11:31

the fire he runs to the bridge to start the

00:11:34

emergency disconnect system, the so-

00:11:36

called

00:11:37

VAT, to shut off the well

00:11:39

on the ocean floor and

00:11:41

prevent the release of oil and gas,

00:11:43

she disconnect platform from the well

00:11:46

is the only way to stop the fire

00:11:49

the only way to save the world

00:11:54

sos sos

00:11:56

and tagged Ryzen motorboat we have an

00:11:58

uncontrollable fire and in gray I said

00:12:04

launches with came to the [ __ ] said

00:12:06

calm down we will not disconnect

00:12:11

sacre-ker I said I must disconnect

00:12:13

from the well and clicked on button and d.s.

00:12:25

oil and gas continue to come out of the well,

00:12:28

fueling the flames and causing explosions, the

00:12:31

emergency disconnection did not work, the

00:12:35

captain returned and said we can

00:12:37

disconnect, to which I replied already rebir,

00:12:49

most of the workers left the platform,

00:12:53

but in the lifeboats of

00:12:59

Egorov 100 we got out of the residential area, the

00:13:01

first thing I saw was that there were lifeguards in the club

00:13:04

Knightley's boats have already been

00:13:07

launched, that they have already left and the hall takes them

00:13:12

to the griller and with them to the spare

00:13:14

life raft, they are among those who

00:13:17

leave the platform, the last one

00:13:21

here, many people do not jump into the water

00:13:24

to escape the unbearable heat, the last

00:13:27

few people remaining on the

00:13:29

platform thrown into the sea from a height of 18 meters

00:13:37

all 115 people who managed to

00:13:39

leave the rig you lived they are gathering

00:13:42

on a supply ship nearby

00:13:45

Jason Andersen the drilling crew

00:13:47

went missing

00:13:50

presumably they died in an

00:13:52

explosion on the drill deck the

00:13:59

oil platform deepwater horizon

00:14:01

burned for 36 hours and then sank crude

00:14:07

oil poured into the Gulf of Mexico,

00:14:14

the world needs to know how a drilling platform with an

00:14:17

exceptional

00:14:19

safety record could suffer a

00:14:21

disaster of this magnitude during a

00:14:23

routine operation when no reaches

00:14:26

the coast of the United States, President

00:14:28

Obama convenes a commission to investigate the

00:14:30

accident,

00:14:32

the disaster currently unfolding

00:14:35

in the Gulf of Mexico may

00:14:37

be the result mistakes of personnel

00:14:39

or corporations taking risks for the sake of and

00:14:42

speeding up work geophysicist Richard Sears

00:14:46

was appointed scientific consultant to

00:14:48

President Obama's national commission

00:14:51

he worked all his life in the

00:14:53

oil industry and was

00:14:55

vice president of the company show what is

00:14:57

more

00:14:58

modern platform competent

00:15:00

companies direct investment in very experienced

00:15:03

personnel and such should not have happened under

00:15:06

any circumstances, what could have gone wrong,

00:15:11

and now by tracking the series of events that

00:15:14

led to the disaster and conducting a detailed

00:15:16

investigation, we will be able to shed light on

00:15:19

how this most complex drilling platform of the

00:15:22

eye burst, which caused the death of

00:15:24

11 people and the emergence of the largest

00:15:27

oil spill full of departure punishment

00:15:33

for us is the key ethyl drilling platform

00:15:35

it holds the record for the depth of the well of

00:15:38

more than ten and a half kilometers

00:15:43

and was serviced by a trans company its

00:15:46

employees have just finished drilling not

00:15:47

Macondo wells for British Petroleum a

00:15:55

huge steel pipe connects the

00:15:58

well you platform one and a half thousand

00:16:00

meters

00:16:02

the well goes to 4000 meters deep into the

00:16:05

earth's crust

00:16:07

there are oil and gas deposits

00:16:09

that are estimated at 110 million

00:16:11

barrels,

00:16:13

but at the moment oil should not

00:16:15

flow into the systems, the

00:16:18

task of the deputy Risen is simply to drill a

00:16:21

well to extract oil, there will be another

00:16:24

platform,

00:16:27

the well will be blocked and temporarily

00:16:29

mothballed,

00:16:36

investigators are beginning to study the process of

00:16:38

conservation, which would have been a

00:16:40

disaster day this is a standard

00:16:42

operation that the team has carried out

00:16:45

several times to

00:16:48

give the frame temporary conservation; this is

00:16:51

when the well is blocked,

00:16:54

concrete plugs are installed,

00:16:55

the capabilities are checked, they are made sure that the

00:16:58

well is stable,

00:17:01

then after a few days or weeks

00:17:04

of my and sometimes months, a

00:17:06

installation arrives to complete the well and

00:17:09

connects it to the corresponding

00:17:11

production facilities out of the water and

00:17:14

acceleration to pinball the

00:17:18

surviving rig workers claim that

00:17:20

Transaction employees installed a

00:17:22

concrete plug in the well and carried out a pressure

00:17:25

test procedure at the wellhead to

00:17:28

check the tightness to make sure

00:17:30

that oil and gas do not enter the system the

00:17:32

well reduces the pressure so that the

00:17:35

pressure inside is less than outside

00:17:40

if there is a leak

00:17:42

oil and gas hydrocarbons will enter the system and an

00:17:45

increase in pressure in the wells will be visible.

00:17:49

You understand the point is to make sure that the

00:17:51

concrete plug at the wellhead

00:17:54

keeps the hydrocarbons inside the

00:17:56

field and does not let milk into it; you

00:17:59

need to make sure that oil and

00:18:02

gas do not rise to the surface only there

00:18:04

will be no need for this

00:18:09

wyman lily the drilling team

00:18:11

monitors changes in pressure inside

00:18:13

the well these pressure readings are also

00:18:16

received on the monitors and the Estonian office of

00:18:18

British Petroleum

00:18:21

Richard Ser now sees exactly the same thing

00:18:24

that the rig employees saw a

00:18:25

few hours before the disaster

00:18:31

from these data it is clearly visible that the pressure

00:18:33

several times rose to almost 10

00:18:36

megapascals if the well had been

00:18:39

sealed the pressure would have remained

00:18:41

constant the

00:18:43

heart sees only one explanation

00:18:47

there is this means that there is a path along

00:18:51

which oil and gas can get into the

00:18:53

well means a plug at the

00:18:56

wellhead there is not ideal strengthening

00:19:01

workers told investigators that

00:19:03

Jason Anderson interpreted the reading as

00:19:06

9600 kilopascals hey otherwise he sat down the

00:19:11

increase in pressure in the addition

00:19:13

due to instrumentation error caused by the bubble effect

00:19:17

he decided that the weight of the liquid in the pipeline

00:19:21

caused the effect of a full bubble

00:19:23

transferring pressure through the closed valve

00:19:26

which led to an increase in pressure in the

00:19:28

well the

00:19:30

head of the drilling british petroleum accepted

00:19:33

Jason's explanations Anderson about the

00:19:36

bubble effect, making the final decision

00:19:39

as to whether the well passed the

00:19:41

test, he agreed that 9700

00:19:44

kilopascals was an instrument error,

00:19:48

but Richard Cyr believes that they were mistaken

00:19:52

during the investigation, we did not meet

00:19:54

anyone, he agreed that he 9700

00:19:59

kilopascals could be due to

00:20:01

something - something like the maguro bubble effect there are

00:20:06

cases of manifestation of such an effect but

00:20:08

usually they are smaller and it did not

00:20:11

seem to us a plausible explanation

00:20:16

of the file they are definitely mistaken but what

00:20:20

exactly prompted them to

00:20:23

make this mistake I just don’t know

00:20:26

this mistake cost Jason Anderson and 10 of

00:20:29

his colleagues their lives

00:20:46

oil industry veteran Professor Bob

00:20:49

Beat investigated 30 incidents at sea

00:20:51

he is an expert in the field of

00:20:53

human factors in disasters and has

00:20:56

thoroughly studied the circumstances

00:20:57

of the deepwater horizon disaster

00:20:59

his vocal cords were damaged by

00:21:01

toxins while investigating the collapse of a dam

00:21:04

in New Orleans

00:21:05

due to Hurricane Katrina was they did not want

00:21:11

blow up the system they didn't want to die he died

00:21:14

so there must be an explanation for that

00:21:17

remember how they did it forge mine

00:21:23

often we only imagine things not as

00:21:25

they are we believe they should be

00:21:29

fhd if we want everything to be in

00:21:32

order we will look for any adventures of

00:21:35

ours points of view did not find any

00:21:39

plausible explanation for the drop in

00:21:41

pressure of the drill string

00:21:42

because they wanted it to have a

00:21:46

simple and logical explanation knife and

00:21:49

towers and sample points to mind, the

00:21:55

drilling team missed the first chance

00:21:58

to understand that the well could break through

00:22:01

this and so the disaster could have been

00:22:03

prevented there was a serious mistake,

00:22:06

but not fatal, the

00:22:15

investigators know that the drillers decided to

00:22:18

carry out the pressure testing procedure of the well

00:22:20

again, giving themselves a second chance to get rid of

00:22:22

the problems,

00:22:26

this time they assessed the pressure through the well

00:22:28

killing line, a small pipe

00:22:30

connecting the platform to the well,

00:22:35

they opened no no and they

00:22:37

saw 30 minutes

00:22:38

but there was no which allowed us to assume that the

00:22:41

pressure in the well was not increasing. Jason

00:22:46

Anderson was sure that oil and

00:22:48

gas leaks were not

00:22:50

the head of the drilling british petroleum

00:22:52

agreed three hours after the start of the

00:22:55

first test, he gave the go-ahead

00:23:04

to the data showing that the pressure in the

00:23:06

drill column at that time remained

00:23:08

at around 9600 k. they didn’t have time,

00:23:11

by analogy with two straws in the

00:23:14

pressure glass of the drill string and the

00:23:16

kill line, it should have been the same, it’s a

00:23:19

valve in one part of the pipe, we see 9,700

00:23:23

rubles in the other, so I want to be, it shouldn’t be

00:23:30

young from the only explanation from my

00:23:32

point of view can for him what for

00:23:35

what - the reason the line was no longer

00:23:37

clogged drunk Lagos, perhaps a foreign

00:23:39

body from the well or lettuce shape, we don’t

00:23:42

know the staff made a conclusion

00:23:47

based on incorrect

00:23:49

instrument readings and neglecting the correct ones,

00:23:52

they did not find out what caused

00:23:55

the ascent, they missed a second chance to understand

00:23:57

that the well is not airtight, a second chance

00:24:00

to prevent a breakthrough

00:24:09

the well,

00:24:10

only it simply wasn’t plugged

00:24:13

if the transaction staff had correctly

00:24:16

interpreted the results of the pressure

00:24:17

testing procedure, it would have become clear at this

00:24:20

stage, it was still possible to shut off the well

00:24:23

at the bottom level and prevent a breakthrough,

00:24:26

this was not done and people paid

00:24:28

for their lives and this is not a drill

00:24:34

now investigators have to understand

00:24:36

why the well was not plugged

00:24:42

Richard Severs found out that the last

00:24:44

equipment the well was installed

00:24:46

outside the ring of disasters on 19

00:24:50

2010 when drilling wells at the lining

00:24:53

the comfort of steel pipes

00:24:59

as soon as the last piece of pipe is placed in the well,

00:25:01

concrete solution is pumped into it,

00:25:06

it passes through the hole and fills the

00:25:07

space Between the casing pipe and the

00:25:09

walls of the well, the hardening

00:25:12

concrete seals the well and prevents

00:25:14

oil and gas from escaping

00:25:17

such burning radiant moment is

00:25:20

that concrete or your wife fill this

00:25:23

annular space around the end of

00:25:26

the pipe with a length of head and kilometers from the

00:25:30

platform to the bottom of the well, evenly

00:25:32

still need to be pumped solution through the pipe

00:25:35

so that it comes out -

00:25:36

this in itself is very very

00:25:39

unpredictable;

00:25:42

at one of the most critical and

00:25:44

difficult stages of drilling a well, people

00:25:47

have to work blindly;

00:25:51

it is important to make sure that the last steel

00:25:54

pipe, the casing pipe, is located

00:25:57

strictly in the center;

00:25:59

if it moves, the solution around it will

00:26:04

remain unevenly distributed. the channel through which oil and gas

00:26:06

will enter the wellbore

00:26:08

the tip is installed using

00:26:11

centralizers they ensure uniform

00:26:13

distribution of the solution we had the

00:26:16

number of centralizers according to their exact

00:26:19

location is selected individually

00:26:20

for each well freeflow

00:26:25

learned there are no clear instructions as to

00:26:28

how many of them are required and there should be

00:26:32

enough to the

00:26:35

casing was well centered

00:26:38

for richard heart the main question was

00:26:41

whether enough centralizer had been installed

00:26:50

[music]

00:26:57

critical decisions about the well were

00:27:00

sometimes made seven hundred kilometers

00:27:01

from the platform in houston where

00:27:04

british petroleum's engineering team is based, including the

00:27:09

company's concrete mortar specialists and liberton

00:27:12

halliburton engineer jesse Galleana

00:27:14

worked in Beppe's office on April 15, 2010,

00:27:21

three days before installing the tip,

00:27:23

Galliano selected the required number of

00:27:25

centralizers

00:27:30

on the drilling platform, there were 6, but he

00:27:33

comes to the conclusion that this number is

00:27:35

not enough,

00:27:37

he recommends using 21

00:27:42

[music]

00:27:44

in the absence of the boss, the bit worker

team leader british petroleum

00:28:03

jong this overrides his decision the new

00:28:09

centralizers are different in design he

00:28:11

is worried they might get stuck on the

00:28:13

way to one well

00:28:14

this could cause him to be way

00:28:16

behind schedule

00:28:24

richard seus reviews

00:28:26

emails between team members

00:28:28

Beppe engineers it

00:28:31

is important that in the correspondence between the

00:28:33

drilling mainland there were

00:28:35

recommendations for using a certain

00:28:37

number of centralizers up to 21

00:28:40

but in the end only 6 were used

00:28:43

British Petroleum engineers decide how to

00:28:49

arrange 6 centralizers one writes a

00:28:53

straight section of pipe even if

00:28:55

the tension does not take a perfectly

00:28:57

central position without

00:28:58

additional devices,

00:29:03

but what difference does it make, it’s done, everything will most likely

00:29:06

work out and we will have a good

00:29:08

concrete plug,

00:29:13

he says that John Guide’s decision was

00:29:15

correct, that in his opinion, the risk

00:29:17

of having to repair the plug is better than the risk of the

00:29:19

centralizers getting stuck in the well, no one

00:29:25

notes the increased danger of a well breakthrough

00:29:28

[music ]

00:29:34

too few centralizers may

00:29:37

have served as the starting point on the path to

00:29:38

the disaster,

00:29:39

but investigators cannot do this

00:29:42

because if the casing pipe is skewed, the

00:29:45

evidence is forever buried five and a

00:29:47

half kilometers below the surface of the

00:29:49

sea,

00:29:52

but there are a number of other circumstances

00:29:55

that can be investigated by the investigator,

00:29:58

it is necessary to establish whether the use was consistent

00:29:59

with

00:30:01

we

00:30:04

know for sure that the hydrocarbons

00:30:07

from this well reached the surface

00:30:09

were due to unforeseen circumstances,

00:30:11

which convincingly indicates

00:30:13

that the cement plug at the wellhead did

00:30:15

not fulfill its function and did not retain

00:30:19

oil and gas inside

00:30:20

the field as it should have been

00:30:26

For each well, a solution of a

00:30:29

unique composition is created; it is a complex mixture of

00:30:31

cement and chemical additives; its beat; the

00:30:36

key criteria for choosing a

00:30:38

solution are the reliability of the solution itself;

00:30:41

that it hardens properly and

00:30:44

has sufficient strength and

00:30:47

the necessary characteristics to

00:30:49

withstand the

00:30:50

pressure applied to it; investigators

00:30:57

study the one developed by the company or

00:30:59

Burton for the well. concrete recipe how

00:31:02

about easy flo

00:31:03

diploma look at the wellbore

00:31:07

was fragile and the concrete had to be

00:31:09

light and the child on becky came to an

00:31:12

agreement regarding nitriding

00:31:14

introducing dispersed nitrogen bubbles to

00:31:16

form foam concrete a controversial

00:31:19

decision with which the owners of the well of the

00:31:21

transaction company did not agree they

00:31:23

believed that nitriding concrete will not be

00:31:25

stable at such a depth

00:31:30

beppi ignored this objection

00:31:32

to this anti more complex concreting

00:31:35

fido if you do not maintain a stable

00:31:37

foam the bubble is supposed to burst that

00:31:39

in fact you can circle such a

00:31:41

formation of large power or even a

00:31:44

channel 1 class any of these phenomena

00:31:53

will lead to a disaster oil and gas

00:31:54

will break through their way into the well and will be

00:31:57

released uncontrollably to the

00:31:59

surface the

00:32:08

halliburton company has a laboratory

00:32:11

for testing concrete in louisiana

00:32:14

february 2010 pilot

00:32:18

testing of enchanted foam concrete is underway

00:32:21

one of the experiments shows that it is not

00:32:24

stable

00:32:25

nitrogen is released to the test strips bubbles

00:32:28

until investigators discovered that x liberton did

00:32:32

not report urgently about this

00:32:34

result british petroleum

00:32:39

two months later hal burton improves the

00:32:42

formula of the solution and conducts a series of more

00:32:44

tests this time on concrete and additives

00:32:47

obtained from the platform experiments

00:32:51

show that gas is still

00:32:52

released and it is very unstable

00:32:56

no one reports this to british petroleum

00:33:01

definitely not the

00:33:04

day before using the solution

00:33:06

in the well halliburton conducts new

00:33:08

tests this time mixing

00:33:10

the solution for a longer time

00:33:14

they make a statement that it works the

00:33:16

solution is stable by the investigator the necessary

00:33:19

evidence they test the

00:33:21

solutions themselves come to the opposite

00:33:23

revelation it was discovered that at

00:33:26

different heights the density is different if

00:33:30

the fact is that the concrete solution itself is

00:33:32

unstable, that it settles into a sediment, a

00:33:36

solid phase falls out, this indicates

00:33:39

that not everything is in order with the solution and that

00:33:41

it cannot be used in addition,

00:33:47

but this is exactly the recipe that the

00:33:50

companies and liberton used for

00:33:52

wells

00:34:08

36 hours after well the drilling platform began to break through,

00:34:13

the pipe connecting to the well sank and was dented

00:34:16

and transferred

00:34:19

within 86 days, crude oil flowed

00:34:23

directly into the Gulf of Mexico, an

00:34:26

oil spill estimated at 5

00:34:29

million barrels

00:34:30

led to environmental and economic

00:34:32

disaster throughout the US

00:34:34

Gulf Coast

00:34:41

only when relief

00:34:43

wells were drilled. Macondo was able to

00:34:45

finally shut down the flow was

00:34:47

stopped, the researchers were able to

00:34:50

begin to solve the final mystery of

00:34:52

why the emergency disconnection did not work

00:34:58

safety equipment in the most

00:35:00

critical situations is located under the

00:35:03

platform

00:35:04

anti-blowout preventer or pvp

00:35:07

similar to a giant crane over 16 meters

00:35:10

in height under normal conditions while

00:35:13

the well is in during

00:35:14

construction, personnel use

00:35:16

valves to control the flow of

00:35:18

fluid into and out of the well

00:35:20

but pvp can also perform an

00:35:23

emergency function designed

00:35:26

to prevent blowouts it should be

00:35:29

noted that there was an uncontrolled

00:35:31

flow of oil and gas to the surface so

00:35:33

obviously pvp you did not block us

00:35:38

the well ate been there

00:35:41

when the platform's emergency release system is turned on,

00:35:46

special steel

00:35:48

clamps slam inside the blowout preventer, which chop off the drill string

00:35:51

and kill the wells, then

00:35:56

the blowout preventer opens

00:35:59

the clamps, allowing the platform to escape.

00:36:07

Investigators believe that Chris

00:36:09

Pleasant's attempts to activate the emergency

00:36:11

release systems failed due to the fact

00:36:13

that the cables connecting the platforms to the pvp

00:36:15

at that time were already damaged by the

00:36:18

explosion, but the blowout preventer

00:36:22

is designed in such a way that this could not

00:36:25

disable them, but in the event of an accident on the

00:36:28

platform, they have a fail-safe

00:36:30

ghoul mechanism, if the connection

00:36:35

between the platform and the pvp ghoul is lost, they are powered

00:36:37

by a battery and should automatically

00:36:39

close the clamps, but as

00:36:44

investigators discovered one the voltage from the batteries

00:36:47

should not have been 27

00:36:50

volts, but in fact 7.6 is not enough to

00:36:54

power the vertical

00:36:59

trans, and he states that at the time of

00:37:02

the explosion the battery was charged and

00:37:04

only later there was no way

00:37:07

to find out how everything was; in fact, there

00:37:13

were also attempts to lead In the

00:37:15

clamping action from the outside with the help of remotely

00:37:18

controlled devices, oil

00:37:21

continued to flow out despite being operational under

00:37:25

normal conditions, the blowout

00:37:27

preventer was unable to cope with the pressure of the

00:37:29

leaking oil after the well broke out

00:37:32

about the bob. This is not surprising. The

00:37:37

damning evidence in the investigation

00:37:39

carried out by the industry regulator in

00:37:42

2002 was generally ignored by those

00:37:43

working in Gulf of Mexico

00:37:45

companies have it I you conducted a

00:37:48

full-scale test on these vb

00:37:51

including the 2001 model Cameron

00:37:54

used on the deep water horizon

00:37:57

and half of them failed

the assembly of the pipe

00:38:02

center half other countries said

00:38:06

that this is not acceptable but what are we doing

00:38:09

we continue to hope for the fact that the clamp

00:38:12

worked and hope is not the best

00:38:15

survival strategy after a six-month thorough

00:38:22

investigation, the national commission

00:38:24

revealed errors that led to a

00:38:26

catastrophic fish accident on the

00:38:28

deepwater horizon drilling platform, the main

00:38:31

reason was that the concrete plug

00:38:34

did not seal the well,

00:38:37

but there were also many other

00:38:39

shortcomings going back to the management of the

00:38:42

involved companies as well as many

00:38:45

opportunities to prevent a disaster

00:38:50

two days before the disaster

00:38:52

the casing was lowered into the well

00:38:54

with only six centralizers my which is 15 better

00:38:59

than the specialist recommended by them and

00:39:00

liberton

00:39:02

this decision baby made in houston

00:39:05

increased the risk of channel formation from

00:39:07

one day before the disaster or burton

to secure the casing pipe,

00:39:20

not the bit employees, not the drilling rig personnel, do

00:39:23

not know how many unsuccessful tests

00:39:25

this solution has had 3:49 before

00:39:30

the disaster,

00:39:32

the tests show that the pressure in the

00:39:35

well is growing, one of the

00:39:37

drilling rig employees believes that the concreting was

00:39:39

unsuccessful and that the well is leaking another

00:39:44

convinces people that these are incorrect

00:39:46

instrument readings, if the

00:39:50

trans employees had already closed the valves at this

00:39:52

stage before the release began, they

00:39:55

would have still had time to plug the well and

00:39:57

avoid a disaster 1:54 before the disaster,

00:40:01

having repeated the pressure

00:40:02

testing procedure, the bureau employees

00:40:04

decide that the concreting was successful

00:40:06

and the well is sealed

00:40:08

they are not aware of the fact that the

00:40:11

well killing line is noticeable

00:40:13

cannot serve as a source of information about

00:40:15

pressure they are not trying to find the reasons for the

now the team is trying to plug

00:40:37

pressure breaks through the blowout

00:40:40

prevent a

00:40:41

raid here and can no longer be eclipsed by the

00:40:46

highly flammable methane bursting

00:40:48

out of the well and enveloping the platform

00:40:52

when it reaches the engine room,

00:40:55

on its way it meets from

00:41:14

[music]

00:41:26

investigators sums it up, both Bibi and

00:41:29

the caliber transaction made a decision

00:41:32

unilaterally,

00:41:33

which increased the chances of a

00:41:36

Macondo well breaking through to them, each of these decisions

00:41:42

individually is well

00:41:44

justified by Vanya, if we consider them

00:41:48

together, they allowed the

00:41:51

incidents to happen, savored the bar and there was no one

00:41:54

who had a common picture of

00:41:55

what was happening and would have seen the system as a

00:41:58

whole, the people who died that night and a

00:42:01

full understanding of

00:42:03

how complex the entire system is, the

00:42:13

investigators pointed to it as the efficiency of

00:42:15

information transfer between three large

00:42:17

companies as a factor that

00:42:20

contributed to what happened

00:42:22

deep water horizon there was a problem with

00:42:24

communications Every step of the way,

00:42:26

both on the platform and on the motherboard,

00:42:28

communication is the main explanation for what

00:42:30

caused

00:42:32

[music]

00:42:40

they wonder whether the speed and

00:42:43
