For any of you wondering what’s going on, they are simply adjusting the six hydrocoptic marzlevanes to eliminate any possibility of side-fumbling in the lunar waneshaft. Normally you’d just realign the two main sperving bearings with the parametric fan, but as you can clearly see, the non reversible tremmie pipe prevented any movement of the differential girdlespring, so naturally they resorted to putting the grammeters in the “up” position. It’s an obvious solution, really.
Exactly! Once the Spurdinator is disconnected and the abbreviation cams are in articulation sequence, the shafterizor will dehydrolate and the seas will calm.
I’ve seen a-lot of horse-shit posted online over the years, but yours is at the very top sport. You are so full of shit, that a 500-Ton OSSV Could hold it all.
at about 7:50 you see the riser tensioners start to close up, the rucker ring comes out of the water and the heave, essentially no longer visible in relation to the riser. That must have been just after the emergency disconnect of the LMRP.
Because the drill ship is connected to the bottom of the sea bed via 2000 something meters of drill pipe. It is essentially tethered to the bottom. When the EDS disconnected the ship from the riser and activated the bop the ship regained stability.
I'm wondering - what happens to a well after an Emergency Disconnect? From what I understand, the riser pipe is deliberately sheared off, so it would seem that such an event means the well cannot be reopened, right?
+CLipka2373 No, the well is sealed. You would have to get a new bop and then drill in another area. When you seal a well opening doesn't mean you can no longer drill that well. Just need to find another position to drill. Could be just few meters away from this one.
+CLipka2373 Depends on where in the well completion you are. If you are using BOP then you just have to put down a new AX/VX Seal and land the bop the same place or you might have to fish for drill string. They can also split the BOP and leave it down to keep the well closed. It's the same deal there also you "simply" change a seal and land it off, but some BOP's dont have removable hydraulics and or power cables so you need to change them on deck. If you have a XT (Xmas Tree) with BOP on top it's the same thing. But usualy the crews offshore are way more proffesional than theese geesers, and they stop before the storm reaches them or do a Controlled Disconnect by the book, an Emergiency Disconnect should really never happen if you know your job :)
Because there no longer held in place by the piping going to the bop. The rig is able to ride on the swells instead of being held down and in place by being connected to the bop.
It's like showing a person and saying, "His body is fighting infection, watch". NOTHING is happening here. A bit more foam, a bit less foam, that's it.
+Javier J You know when the weather is comming up. So you prepeare for the disconnect. The BOP is made in two parts. The BOP itself, and the LMRP Lower marine riser package. When you see the weather comming up. You pull the pipe from the hole, and displace the riser with saltwather. Mud costs money, and you dont want a spill to the sea, so this with som saltwather goes back in the mud pit. You close a valve in the BOP, and one in the LMRP. And then you are ready to disconnect. You try to stay connected as long as you can. Cuz the weather have to be very calm to connect the LMRP again. In this case the will have to connect again when the weather is calm again. Open the valves dicplase the riser with mud again. And commence drilling. If you dont have time to pull out the pipe, you use the rams in the BOP to hang off the pipe. Then you do the mentiond above. The BOP is left on the seabed and holds the fluids and preassure. The BOP is also pressure tested sevral times a week. After disconneting, you move the rig, or drillship from the template over in a safe zone. So when the weather is realy bad, if something falls of the rig or ship. It will not hit the BOP and damage it.

When the ship is connected it can't bob up and down on top of the waves so the waves come up into the moon pool. When it disconnects it can float and bob on top of the swells.
I can assure you when the ship is connected it does bob up and down. The systems will generally allow for up to 48 feet. However, once the heave gets near 30 feet or the rig is in danger of being forced off location, they will disconnect. I have seen a rig heaving 35 feet before disconnect.
The tensioners looked a little tight/slow. Most likely 5he 5310s. They got replaced by 6400s the reduced shear and response time. Totally preventable by a tension operator with some exp, not the union shills making hemmorhoids.

‘Obviously’. 😏
I'm gonna act as if I understood all that
I mean.... that makes perfect sense
Exactly!

Once the EDS is fired shears rams close , blind rams close and annul close , C&K connector and LMRP connector unlatch an LMRP is lifted away .
At the 7:30 mark you can see steam/vapour/gas/insert here coming out of the top of the riser.
Thats so crazy! kudos to the guys that invented this stuff
Don’t know how I ended up here but everyone in the comments seems to really know their stuff.
Why is the water in the moon pool so damn rough at first (e.g. 4:54) and then so eerily calm later on?? (e.g. 8:20)
Because the drill ship is connected to the bottom of the sea bed via 2000 something meters of drill pipe. It is essentially tethered to the bottom. When the EDS disconnected the ship from the riser and activated the bop the ship regained stability.
That’s an insane amount of movement.
This videos are excellent even thou i have worked offshore more than 10 years still i am learning thank for this videos.

No No the upper marine riser/BOP would be released and rig pulled away from wellhead with anchors
@@co3lh4 Rubbish
im not familiar with offshore drilling but why did the swell suddenly stop once they disconnected?
Because there no longer held in place by the piping going to the bop. The rig is able to ride on the swells instead of being held down and in place by being connected to the bop.
skip to 9:36 save yourself the disappointment
Lol
I can't think of any industry making more than the oil drilling industry yet still we get basic 480p
And no sound lmfao
For security camera footage it's basically HD😄. Compared to usual ones that's black and white in 5 fps
480 but at least it has low light capability
Omg got to get out of here, this place is going to blow!
Must of been scary af. Don't underestimate the sea, it'll be the last thing you do...
Soutwoods city
hello old me
To me that thing looked really scary. I'd hate to fall into it!
ya.
@misatogang Have you ever stepped near to a dam's spill gate? That's some scary stuff too.
@ 7:30 is were the last big wave movements happen
what is eds
nice video, i like it . thank you for upload
Nothing happened. 10 minutes of my life gone, watching nothing happen.
lol looks like a crazy swimming pool
That's the point. The safety triggered and it reduces the sway saving the gear and ship. The less dramatic the better.
I lol so hard on this one for some reason.
@@mostlyjoe Exactly.
arnt ya suppose to be on bubble watch?
at what time exactly did it discontent ?
A little splishy splashy, then peace and tranquility
is this the Chikyu?
I see that the riser is disconnected. I would be interested in seeing the disconnection mechanism. Interesting!
Here you have ua-cam.com/video/QL25WM_5Z80/v-deo.html
So nothing happened?
why is it called moon pool?
This is not really a disconnect as the pinon didn't come loose.
It looks black because there is not as much turbulance in the water. No bubbles in other words. It isn't oil it is just the deep dark ocean.
Thats why Multiplex Subsea Engineers get the big bucks
i remember that hitch, was on chikyu in 2006-2007 fun times :)
Did they get the mantle?
If it was OD21 that was Cameron BOP stack on bottom
It's like showing a person and saying, "His body is fighting infection, watch". NOTHING is happening here. A bit more foam, a bit less foam, that's it.
This video was intended for the people who understands the process.
Does this argument still work in the USSR?
does the fact where I'm from still relevant these days?
I don't know but that's what Soviet people's mindset is - "it's for professionals, you won't understand".
Subsea
what happens to the pipe and well head?
+Javier J Left behind.

I wonder why they then failed to do this at deepwater horizon
They tried. There is a lot of videos about why here on youtube. Explains better than me i think ;)
+beeeneee the pipe was bent in the BOP and the shears couldn't cut it. Like the other guy said, videos explain it better.
Amazing machinery.
I remember when watching paint dry was exciting
Why not disconnect before storm
Cause theres FOOKIN money down there m8
So, what's the score here? Is that ship now bobbing around with 6,000' of pipe hanging from the moon pool? *impressed whistle
Yes
I watched that about 20 times.All in slow mode.lol
10 minutes I'll never get back.

Bad Supervision because the BOP should have been pulled long before an emergency disconnect!
